DAY 1 Q1 of 30 • Scarcity
TSIA2 Revising: Transition Words
(1) In any economic system, productive resources are inherently finite while human wants remain boundless. (2) For instance, societies cannot produce every desirable good, forcing consumers and governments to evaluate opportunity costs.
Which transition word or phrase is most effective to replace the underlined phrase in sentence 2?
A. In contrast
B. Consequently
C. Meanwhile
D. Furthermore
DAY 1 KEY Question 1 Review
TEKS Econ: Scarcity & Opportunity Cost
B
Correct Answer
Consequently
TSIA2 Explanation
Sentence 2 states the direct outcome of the condition described in sentence 1. "Consequently" signals a cause-and-effect link. "For instance" implies sentence 2 is a specific example rather than a logical result.
TSIA2 Strategy • The Relationship Bridge
Identify the logical bond between sentences before looking at options: is it cause/effect, contrast, addition, or example? Here: finite resources (cause) → forced trade-offs (effect).
DAY 1 Q2 of 30 • Factors of Production
TSIA2 Editing: Subject-Verb Agreement
(1) Economists categorize resources into land, labor, capital, and entrepreneurship. (2) The total expenditure on capital equipment, including robotic assembly arms and specialized machinery, are calculated before factory operations commence.
Which correction should be made to sentence 2?
A. Change equipment to equipments
B. Change including to which include
C. Change are calculated to is calculated
D. Change commence to commenced
DAY 1 KEY Question 2 Review
TEKS Econ: Factors of Production (Capital)
C
Correct Answer
Change "are calculated" to "is calculated"
TSIA2 Explanation
The grammatical subject of sentence 2 is the singular noun phrase "The total expenditure." The prepositional phrases and modifier ("on capital equipment, including robotic assembly arms...") are nonessential interruptions. A singular subject requires the singular verb "is calculated."
TSIA2 Strategy • The Interrupter Strip Test
Cross out all prepositional phrases and modifying clauses between the subject and verb: "The total expenditure [...] is calculated." Never let nearby plural nouns mislead your ear.
DAY 2 Q3 of 30 • Production Possibilities
TSIA2 Reading: Central Idea
A Production Possibilities Curve (PPC) illustrates the maximum combinations of two goods an economy can generate given fixed technology and resources. Points along the frontier demonstrate productive efficiency. Conversely, points situated inside the frontier reflect underutilized resources such as idle labor, while points outside the boundary represent unattainable output levels under prevailing economic conditions.
Which statement best expresses the central idea of the passage?
A. The PPC models economic efficiency, resource limits, and trade-offs.
B. Economies should consistently allocate equal resources between two products.
C. Idle factories and unemployed workers prevent PPC curves from shifting outward.
D. New technology always moves an economy inside its production boundary.
DAY 2 KEY Question 3 Review
TEKS Econ: Production Possibilities Frontier
A
Correct Answer
The PPC models economic efficiency, resource limits, and trade-offs.
TSIA2 Explanation
The text explains how the PPC visually summarizes productive efficiency (on the curve), underutilization (inside), and scarcity limits (outside). Option A captures this comprehensive definition without introducing extraneous claims.
TSIA2 Strategy • Scope Verification
Central idea choices must encompass the whole passage. Reject choices that highlight only one detail (like underutilization in C) or make unfounded generalizations not supported by the text (B and D).
DAY 2 Q4 of 30 • Specialization
TSIA2 Revising: Sentence Combining
(1) Workers specialize in repetitive production tasks. (2) They develop advanced technical proficiency. (3) This specialization reduces per-unit manufacturing costs.
Which choice most effectively combines sentences 1, 2, and 3 into a single clear sentence?
A. Specializing in repetitive tasks, workers develop technical proficiency, thereby reducing per-unit manufacturing costs.
B. Workers specialize in repetitive tasks, and they develop proficiency, and it reduces manufacturing costs per-unit.
C. Because manufacturing costs are reduced per unit, workers specialize in repetitive tasks developing proficiency.
D. Although workers specialize in repetitive tasks, technical proficiency reduces per-unit manufacturing costs.
DAY 2 KEY Question 4 Review
TEKS Econ: Division of Labor & Productivity
A
Correct Answer
Option A (Participial Phrase Combination)
TSIA2 Explanation
Option A subordinates the first action with a participial phrase ("Specializing in..."), keeps the active subject ("workers"), and smoothly connects the final outcome ("thereby reducing..."). Option B is a clunky run-on, C reverses cause and effect, and D uses an illogical contrast word ("Although").
TSIA2 Strategy • Conciseness and Logic Check
TSIA2 sentence-combining questions favor concise structures that maintain logical cause-and-effect relationships and avoid repetitive coordinating conjunctions ("and... and...").
DAY 3 Q5 of 30 • Economic Systems
TSIA2 Editing: Punctuation (Semicolons)
(1) In a pure market economy, decentralized price signals allocate scarce resources efficiently, however, in a command system government planners dictate all production quotas.
Which option correctly punctuate the underlined portion of sentence 1?
A. efficiently however in a command system,
B. efficiently; however, in a command system,
C. efficiently: however; in a command system
D. efficiently, however; in a command system,
DAY 3 KEY Question 5 Review
TEKS Econ: Market vs Command Economies
B
Correct Answer
efficiently; however, in a command system,
TSIA2 Explanation
The original sentence commits a comma splice by connecting two independent clauses with only a comma and the conjunctive adverb "however." Two complete thoughts joined by a conjunctive adverb require a semicolon before the transition and a comma after it.
TSIA2 Strategy • The Semicolon + Conjunctive Adverb Formula
Remember the standard punctuation pattern: [Independent Clause] ; [however / therefore / furthermore] , [Independent Clause]. Never join independent clauses with just a comma.
DAY 3 Q6 of 30 • Free Enterprise
TSIA2 Reading: Vocabulary in Context
In Texas and throughout the United States, the free enterprise system enshrines the principle of consumer sovereignty. By exercising their purchasing power, consumers cast monetary "dollar votes" that dictate which goods firms continue to supply and which unprofitable enterprises fail.
As used in the passage, the word "sovereignty" most nearly means:
A. royal lineage or heritage
B. legal immunity from prosecution
C. supreme decision-making power
D. geographic national independence
DAY 3 KEY Question 6 Review
TEKS Econ: Consumer Sovereignty & Free Enterprise
C
Correct Answer
supreme decision-making power
TSIA2 Explanation
The surrounding context explains that consumers "cast monetary dollar votes that dictate which goods firms continue to supply." In this economic context, sovereignty describes the ultimate authority consumers wield over market production.
TSIA2 Strategy • The Context Replacement Test
Substitute each option back into the original sentence: "...the principle of consumer [supreme decision-making power]." Only Choice C aligns with the explanation of consumer dollar votes.
DAY 4 Q7 of 30 • Demand & Elasticity
TSIA2 Revising: Supporting Evidence
(1) The Law of Demand states that as the price of a good rises, quantity demanded falls. (2) However, price elasticity of demand varies significantly across different product categories. (3) [ INSERT SENTENCE ] (4) In contrast, luxury vacation packages experience steep declines in buyer demand following minor price spikes.
Which sentence provides the most relevant supporting evidence for sentence 2 when inserted at position 3?
A. For life-saving medications like insulin, consumers maintain steady purchases regardless of steep price increases.
B. Many economists graduated from universities located throughout the state of Texas.
C. Advertising campaigns frequently persuade shoppers to purchase items they initially did not intend to buy.
D. Production costs for consumer electronics have dropped consistently over the previous decade.
DAY 4 KEY Question 4 Review
TEKS Econ: Price Elasticity of Demand
A
Correct Answer
Option A (Inelastic necessity evidence)
TSIA2 Explanation
Sentence 2 introduces variation in price elasticity. Sentence 4 provides an example of elastic demand (luxury vacations). Position 3 requires the opposing counterpart: an inelastic necessity (insulin) that contrasts directly with sentence 4.
TSIA2 Strategy • Bookend Context Analysis
Read both the sentence before AND the sentence after the insertion point. Notice the transition "In contrast" in sentence 4: sentence 3 must describe a product whose demand does NOT decline when prices rise.
DAY 4 Q8 of 30 • Business Organizations
TSIA2 Editing: Pronoun-Antecedent Agreement
(1) A sole proprietor enjoys complete operational control and retains all business profits. (2) However, if the enterprise defaults on bank obligations, they face unlimited personal liability for every outstanding debt incurred.
Which edit corrects the pronoun error in sentence 2?
A. Change they face to he or she faces
B. Change they face to we face
C. Change they face to it face
D. Change they face to the owners faces
DAY 4 KEY Question 8 Review
TEKS Econ: Sole Proprietorship & Liability
A
Correct Answer
Change "they face" to "he or she faces"
TSIA2 Explanation
The antecedent is "A sole proprietor," which is singular. In formal standardized editing passages on the TSIA2, singular indefinite or gender-neutral singular antecedents require singular pronouns ("he or she faces" or restructuring to the singular owner).
TSIA2 Strategy • Antecedent Tracing
Locate the noun the pronoun replaces. Trace back: who faces liability? "A sole proprietor" (singular). Match singular with singular and plural with plural.
DAY 5 Q9 of 30 • Price Controls
TSIA2 Reading: Author's Purpose
While rent control ordinances are enacted to shield low-income urban families from soaring rental costs, empirical economic data reveals that statutory price ceilings consistently induce persistent housing shortages. When legal rents are capped below market equilibrium, landlords defer maintenance, convert apartments into commercial condos, and reduce new construction. Consequently, the very demographic policymakers intend to assist frequently confronts severe rationing and diminished living conditions.
The primary purpose of the passage is to:
A. Advocate for the complete deregulation of all municipal zoning laws.
B. Explain how artificial price ceilings create unintended market distortions.
C. Praise municipal governments for protecting vulnerable urban tenants.
D. Detail specific tax incentives available to residential real estate developers.
DAY 5 KEY Question 9 Review
TEKS Econ: Price Ceilings & Equilibrium Shortages
B
Correct Answer
Explain how artificial price ceilings create unintended market distortions.
TSIA2 Explanation
The author evaluates the gap between policy intent (helping low-income renters) and economic reality (shortages, deferred maintenance, diminished supply). The passage is an explanatory analysis of unintended consequences.
TSIA2 Strategy • Tone & Verb Scrutiny
Analyze the leading verb in each answer choice: "Advocate," "Explain," "Praise," "Detail." The author's tone is objective and analytical, making "Explain" the exact match.
DAY 5 Q10 of 30 • Law of Supply
TSIA2 Revising: Sentence Placement
(1) According to the Law of Supply, producers offer higher quantities of a good at higher prices. (2) Higher market prices signal opportunities for increased profit margins. (3) Conversely, when market prices collapse, marginal firms curtail output or shutter unviable production facilities. (4) [Sentence to place: Motivated by these potential returns, existing firms expand manufacturing shifts and new competitors enter the market.]
Where should the sentence above be placed to create the most logical progression?
A. Before sentence 1
B. Immediately after sentence 1
C. Immediately after sentence 2
D. Immediately after sentence 3
DAY 5 KEY Question 10 Review
TEKS Econ: Law of Supply & Producer Incentives
C
Correct Answer
Immediately after sentence 2
TSIA2 Explanation
The sentence opens with "Motivated by these potential returns," which directly links to "opportunities for increased profit margins" in sentence 2. Placing it after sentence 2 also preserves the contrast introduced by "Conversely" in sentence 3.
TSIA2 Strategy • Demonstrative Pronoun Clues
Look for demonstrative phrases like "these potential returns." The sentence preceding it MUST mention those specific returns or profits! Sentence 2 explicitly mentions profit margins.
DAY 6 Q11 of 30 • Market Structures
TSIA2 Editing: Parallel Structure
(1) Pure monopolies maintain dominant market share by establishing insurmountable barriers to entry. (2) These structural barriers include securing exclusive patents, to control essential raw materials, and leveraging massive economies of scale.
Which revision of the underlined portion creates correct parallel structure?
A. controlling essential raw materials, and leveraging massive economies
B. to control essential raw materials, and to leverage massive economies
C. controlling essential raw materials, and they leverage massive economies
D. essential raw materials are controlled, and leveraging massive economies
DAY 6 KEY Question 11 Review
TEKS Econ: Monopoly & Barriers to Entry
A
Correct Answer
controlling essential raw materials, and leveraging massive economies
TSIA2 Explanation
The list begins with the gerund "securing exclusive patents." To preserve parallel grammatical structure, every item in the series must follow the same gerund (-ing) pattern: "securing..., controlling..., and leveraging..."
TSIA2 Strategy • The Series Pattern Match
When words appear in a list or series connected by "and" or "or," inspect their verb forms. Match: Gerund + Gerund + Gerund (-ing, -ing, -ing) or Infinitive + Infinitive + Infinitive (to X, to Y, to Z).
DAY 6 Q12 of 30 • Oligopoly
TSIA2 Revising: Deleting Irrelevant Details
(1) In an oligopolistic market structure, a handful of dominant corporations control the vast majority of industry sales. (2) Because firms are interdependent, any price adjustment by one airline or wireless provider triggers retaliatory moves by rivals. (3) To avoid devastating price wars, oligopolies engage in non-price competition such as aggressive branding. (4) Many corporate executives prefer flying in private aircraft when attending shareholder conventions. (5) Consequently, advertising budgets in oligopolies represent substantial operational costs.
Which sentence should be deleted because it introduces irrelevant information?
A. Sentence 2
B. Sentence 3
C. Sentence 4
D. Sentence 5
DAY 6 KEY Question 12 Review
TEKS Econ: Oligopoly & Non-Price Competition
C
Correct Answer
Sentence 4 should be deleted
TSIA2 Explanation
The paragraph develops the economic concept of oligopolistic market interdependence and non-price competition (advertising). Sentence 4 introduces an irrelevant personal detail about executive travel habits that disrupts the analytical focus.
TSIA2 Strategy • The Paragraph Focus Filter
Summarize the main topic in 3 words: "Oligopoly marketing strategy." Test each sentence against that filter. Sentence 4 describes executive perks, which does not belong.
DAY 7 Q13 of 30 • Corporations
TSIA2 Reading: Making Inferences
A corporation is legally chartered as a distinct entity separate from its owners. While sole proprietors and general partners face unlimited liability for enterprise debts, corporate shareholders enjoy limited liability; an investor can lose no more than the capital originally paid for shares. Furthermore, corporations benefit from perpetual existence, meaning ownership can transfer seamlessly across generations through equity markets without dissolving the underlying company.
Based on the passage, it can be reasonably inferred that corporations:
A. Are immune to all commercial taxes and federal regulatory oversight.
B. Present less personal financial risk to passive investors than partnerships do.
C. Must dissolve and reincorporate whenever a major shareholder passes away.
D. Are restricted from issuing public equity shares to raise capital.
DAY 7 KEY Question 13 Review
TEKS Econ: Business Structures & Limited Liability
B
Correct Answer
Present less personal financial risk to passive investors than partnerships do.
TSIA2 Explanation
The passage states that general partners face "unlimited liability" while shareholders "can lose no more than the capital originally paid." Thus, an investor faces far less personal financial risk in a corporate structure.
TSIA2 Strategy • The Text-Evidence Tether
An inference question on the TSIA2 must be directly tethered to explicit facts in the text. Look for the exact contrast: "unlimited liability" (partners) vs. "limited liability" (shareholders).
DAY 7 Q14 of 30 • Business Mergers
TSIA2 Editing: Comma Splice Correction
(1) Horizontal mergers consolidate competing firms operating in the same industry, vertical mergers unite companies at different stages of the production process.
Which choice best corrects the underlined portion of sentence 1?
A. industry, whereas vertical mergers unite companies at different stages
B. industry vertical mergers unite companies at different stages
C. industry, and while vertical mergers unite companies at different stages
D. industry, so vertical mergers unite companies at different stages
DAY 7 KEY Question 14 Review
TEKS Econ: Horizontal & Vertical Mergers
A
Correct Answer
industry, whereas vertical mergers unite companies...
TSIA2 Explanation
The original sentence separates two independent clauses with only a comma, creating a comma splice. Choice A resolves this by introducing the subordinating conjunction "whereas," which clearly signals the conceptual contrast between horizontal and vertical mergers.
TSIA2 Strategy • Comma Splice Remedies
You can fix a comma splice in three ways: 1) Period and capital letter, 2) Semicolon, or 3) Subordinating conjunction (like "whereas" or "although"). Choice A correctly uses subordination.
DAY 8 Q15 of 30 • Functions of Money
TSIA2 Revising: Word Choice & Precision
(1) Money serves three fundamental functions: a medium of exchange, a unit of account, and a store of value. (2) During periods of hyperinflation, fiat currency loses its ability to act as a store of value because its buying power stuff vanishes extremely fast.
Which revision of the underlined phrase provides the most precise and academic economic tone?
A. spending muscle disappears in a hurry
B. purchasing power erodes rapidly
C. cash worth goes downhill immediately
D. dollar abilities drop down right away
DAY 8 KEY Question 15 Review
TEKS Econ: Three Functions of Money
B
Correct Answer
purchasing power erodes rapidly
TSIA2 Explanation
The terms "purchasing power" and "erodes rapidly" represent standard formal economic vocabulary. The other options employ colloquial phrasing ("stuff," "spending muscle," "goes downhill") inappropriate for formal informational writing.
TSIA2 Strategy • The Academic Register Check
TSIA2 revising items test formal academic register. Eliminate slang, idioms, or vague words ("stuff," "things," "a lot"). Choose domain-specific vocabulary that conveys exact meaning.
DAY 8 Q16 of 30 • Banking System
TSIA2 Editing: Verb Tense Consistency
(1) Under fractional reserve banking, financial institutions maintain a mandatory fraction of customer deposits in vault reserves. (2) Commercial banks then loaned out excess reserves to businesses and homebuyers, which expands the nation's broad money supply.
Which change is necessary to ensure consistent verb tense in sentence 2?
A. Change loaned out to loan out
B. Change expands to expanded
C. Change maintain to maintained
D. Change loaned out to had loaned out
DAY 8 KEY Question 16 Review
TEKS Econ: Fractional Reserve Banking
A
Correct Answer
Change "loaned out" to "loan out"
TSIA2 Explanation
The passage describes an ongoing economic process stated in the present tense ("maintain" in sentence 1, "expands" in sentence 2). Changing the past-tense verb "loaned out" to the present-tense "loan out" restores consistency across the sentences.
TSIA2 Strategy • Timeline Consistency
Check the anchor tense of the passage. Explanations of general scientific or economic principles belong in the simple present tense: banks maintain → banks loan out → this expands.
DAY 9 Q17 of 30 • Monetary Policy
TSIA2 Reading: Evaluating Arguments
To combat soaring inflation, the Federal Reserve executes contractionary monetary policy. By selling government securities on the open market, the Fed absorbs bank reserves, compelling commercial institutions to elevate the federal funds rate. Consequently, interest rates for mortgages, commercial loans, and credit cards escalate. While this strategy successfully dampens aggregate consumer spending and cools price growth, it simultaneously risks triggering recessionary contractions and higher unemployment rates.
The author structures the argument primarily by:
A. Contrasting the personal leadership philosophies of past Federal Reserve Chairs.
B. Tracing the operational steps of a policy and weighing its trade-offs.
C. Arguing that inflation is preferable to any increase in nationwide unemployment.
D. Outlining the legislative procedure Congress follows to approve interest rate changes.
DAY 9 KEY Question 17 Review
TEKS Econ: The Federal Reserve & Monetary Policy
B
Correct Answer
Tracing the operational steps of a policy and weighing its trade-offs.
TSIA2 Explanation
The text outlines sequential steps (selling bonds → absorbing reserves → raising interest rates) and then weighs its dual outcomes: the intended benefit (cooling inflation) versus the risk (recession and unemployment).
TSIA2 Strategy • Structural Mapping
Notice transition markers like "By selling...," "Consequently...," and "While this strategy... it simultaneously risks." This progression outlines causal steps followed by trade-offs.
DAY 9 Q18 of 30 • Fed Tools
TSIA2 Revising: Sentence Combining
(1) The Federal Reserve can alter the discount rate. (2) The Federal Reserve can also adjust reserve requirements. (3) Both actions regulate the overall lending capacity of commercial banking institutions.
Which choice combines these sentences into the most concise and coherent statement?
A. The Federal Reserve can alter the discount rate, and they adjust reserve requirements, which regulates commercial banks' capacity.
B. By altering the discount rate and adjusting reserve requirements, the Federal Reserve regulates the lending capacity of commercial banks.
C. Lending capacity of commercial banks is regulated by the Fed who can alter the discount rate while reserve requirements are adjusted.
D. Although the Federal Reserve alters the discount rate, adjusting reserve requirements regulates commercial banks' lending capacity.
DAY 9 KEY Question 18 Review
TEKS Econ: Monetary Policy Tools
B
Correct Answer
Option B (Prepositional clause combining tools)
TSIA2 Explanation
Option B efficiently combines the two actions using parallel gerunds ("altering... and adjusting...") in an introductory prepositional phrase, clearly identifying the Federal Reserve as the active agent performing the regulation.
TSIA2 Strategy • Active Voice Priority
When combining sentences, eliminate repetitive subject mentions ("The Fed can... The Fed can...") and prioritize clear, active voice over awkward passive constructions (such as Option C).
DAY 10 Q19 of 30 • Fiscal Policy
TSIA2 Editing: Dangling Modifiers
(1) Hoping to stimulate consumer demand during an economic downturn, tax rebate checks were mailed by the federal government to millions of working households.
Which revision of sentence 1 properly resolves the dangling modifier?
A. Hoping to stimulate consumer demand during an economic downturn, the federal government mailed tax rebate checks to millions of working households.
B. Hoping to stimulate consumer demand during an economic downturn, mailing tax rebate checks was completed by the federal government.
C. Tax rebate checks were mailed by the federal government to millions of working households hoping to stimulate consumer demand.
D. During an economic downturn hoping to stimulate consumer demand, tax rebate checks were mailed by the federal government.
DAY 10 KEY Question 19 Review
TEKS Econ: Fiscal Policy & Government Stimulus
A
Correct Answer
Option A (Placing "the federal government" right after the modifier)
TSIA2 Explanation
The introductory participial phrase "Hoping to stimulate consumer demand..." describes the entity doing the hoping. Paper checks cannot hope; "the federal government" must immediately follow the comma as the subject.
TSIA2 Strategy • The Modifier Snap Rule
Whenever a sentence begins with an "-ing" introductory phrase, ask: "WHO is doing this action?" That specific actor MUST be placed immediately after the comma.
DAY 10 Q20 of 30 • Taxation Systems
TSIA2 Revising: Transition Words
(1) A progressive income tax assesses higher percentage rates on upper-income earners than on low-income citizens. (2) Similarly, a regressive sales tax imposes a disproportionately greater financial burden on low-wage workers relative to their total earnings.
Which transition word or phrase is most effective to replace the underlined word in sentence 2?
A. For example
B. In contrast
C. Consequently
D. As a result
DAY 10 KEY Question 20 Review
TEKS Econ: Progressive vs Regressive Taxation
B
Correct Answer
In contrast
TSIA2 Explanation
Sentence 1 describes a progressive tax that burdens high earners, while sentence 2 describes a regressive tax that burdens low earners. These two tax structures represent opposing economic concepts, requiring the contrast transition "In contrast."
TSIA2 Strategy • Directional Comparison
Compare the directional polarity of both sentences: sentence 1 (wealthy pay higher share) vs. sentence 2 (poor pay higher share of income). Opposing directions require contrast transitions.
DAY 11 Q21 of 30 • Economic Indicators
TSIA2 Reading: Text Structure
Macroeconomists quantify national production through Gross Domestic Product (GDP), which aggregates four discrete expenditure categories: personal consumption expenditures (C), gross private domestic investment (I), government consumption expenditures (G), and net exports of goods and services (Xn). Each category reflects the spending decisions of distinct economic sectors—households, businesses, public entities, and international trading partners.
The primary organizational structure of the passage is:
A. Chronological narrative
B. Classification and division
C. Problem and solution
D. Cause and effect
DAY 11 KEY Question 11 Review
TEKS Econ: GDP Components (C + I + G + Xn)
B
Correct Answer
Classification and division
TSIA2 Explanation
The author breaks down a single macro concept (GDP) into four discrete categories (consumption, investment, government, net exports) and explains the role of each sector. This is the definition of classification and division.
TSIA2 Strategy • Pattern Identification
Look for signaling words: "aggregates four discrete categories," "Each category reflects..." Dividing a broad subject into functional subsets signals a classification structure.
DAY 11 Q22 of 30 • Inflation & CPI
TSIA2 Editing: Apostrophes & Possessives
(1) The Consumer Price Index measures price fluctuations across a typical urban consumers market basket of retail goods and services. (2) When the index climbs steeply, household purchasing power deteriorates.
Which revision correctly represents the possessive noun in sentence 1?
A. consumer's market basket
B. consumers's market basket
C. consumers market basket's
D. consumer market basket's
DAY 11 KEY Question 22 Review
TEKS Econ: Consumer Price Index & Inflation
A
Correct Answer
consumer's market basket
TSIA2 Explanation
The market basket belongs to "a typical urban consumer" (singular). Singular nouns show possession by adding an apostrophe followed by "s": consumer's market basket.
TSIA2 Strategy • The "Of" Inversion Test
Invert the phrase using "of": "the market basket of a typical urban consumer." Because "consumer" is preceded by "a," it is singular. Add 's to form singular possession.
DAY 12 Q23 of 30 • Unemployment Types
TSIA2 Revising: Topic Sentences
(1) [ TOPIC SENTENCE ] (2) In industrial manufacturing, automated robotic welding units have permanently eliminated thousands of manual assembly line roles. (3) Displaced workers cannot readily transition to software programming positions without extensive retraining. (4) Unlike short-term frictional unemployment, this structural skills mismatch can endure for years.
Which topic sentence most effectively introduces the paragraph?
A. Structural unemployment emerges when technological innovations render specific vocational skills obsolete.
B. Seasonal unemployment occurs routinely in agricultural regions following autumn harvests.
C. Many college graduates spend several months interviewing before accepting an entry-level position.
D. The natural rate of unemployment in Texas usually hovers between four and five percent.
DAY 12 KEY Question 23 Review
TEKS Econ: Structural vs Frictional Unemployment
A
Correct Answer
Option A (Introducing structural unemployment via technology)
TSIA2 Explanation
Sentences 2, 3, and 4 specifically detail robotic automation eliminating factory jobs and creating a lasting "structural skills mismatch." Option A establishes the exact topic and controlling idea.
TSIA2 Strategy • Paragraph Synthesis
Read the supporting details first (robotics displacing workers, need for retraining, structural mismatch). An effective topic sentence must provide an overarching umbrella for all of those specific details.
DAY 12 Q24 of 30 • Business Cycles
TSIA2 Editing: Run-on Sentences
(1) During the expansionary phase of the business cycle gross domestic product climbs and unemployment drops at the peak the economy operates at maximum capacity then a contraction begins.
Which revision resolves the run-on sentence most effectively?
A. drops. At the peak, the economy operates at maximum capacity; then, a contraction begins.
B. drops, at the peak the economy operates at maximum capacity, then a contraction begins.
C. drops at the peak, the economy operates at maximum capacity and then a contraction begins.
D. drops, but at the peak the economy operates at maximum capacity so then a contraction begins.
DAY 12 KEY Question 24 Review
TEKS Econ: Business Cycle Phases
A
Correct Answer
Option A (Separating independent clauses with period and semicolon)
TSIA2 Explanation
The original sentence fuses multiple independent clauses without punctuation (a fused run-on). Option A uses a period to complete the first clause and a semicolon with an introductory adverb ("then") to correctly punctuate the subsequent clauses.
TSIA2 Strategy • Independent Clause Isolation
Count the independent subjects and predicates: 1) "gross domestic product climbs," 2) "the economy operates," 3) "a contraction begins." Each requires deliberate punctuation or conjunctions.
DAY 13 Q25 of 30 • Comparative Advantage
TSIA2 Reading: Drawing Conclusions
Economist David Ricardo demonstrated that absolute advantage—producing more units of a good than a rival using identical inputs—does not govern mutually beneficial trade. Instead, trade patterns should reflect comparative advantage: producing a good at a lower relative opportunity cost. Even if Nation A holds an absolute advantage across every commodity, both nations maximize consumption by specializing in items with the lowest opportunity cost and trading for the remainder.
Which conclusion is most logically supported by the passage?
A. Nations should avoid international trade if they lag behind in manufacturing technology.
B. Comparative advantage allows less efficient producers to benefit from global commerce.
C. A country with an absolute advantage in all goods has no economic incentive to trade.
D. Specialization leads to decreased overall consumption across trading partners.
DAY 13 KEY Question 25 Review
TEKS Econ: Comparative Advantage (David Ricardo)
B
Correct Answer
Comparative advantage allows less efficient producers to benefit from global commerce.
TSIA2 Explanation
The passage notes that even when one nation holds an absolute advantage in every commodity, "both nations maximize consumption by specializing in items with the lowest opportunity cost." Thus, even less efficient nations gain from trade.
TSIA2 Strategy • Extreme Language Elimination
Eliminate choices containing absolute or contradicted words: "avoid... trade" (A), "no economic incentive" (C), "decreased... consumption" (D). Choice B is measured, logical, and supported.
DAY 13 Q26 of 30 • Trade Benefits
TSIA2 Revising: Eliminating Redundancy
(1) Expanding international commerce enables domestic consumers to access an unprecedented diversity of foreign goods. (2) Furthermore, competition from abroad compels local manufacturers to eliminate unnecessary waste that is completely unneeded and superfluous in their supply chains.
Which revision of the underlined portion is most concise and eliminates repetitive phrasing?
A. unnecessary waste and unneeded excess
B. wasteful excesses that are not necessary
C. unnecessary waste
D. superfluous waste that is extra
DAY 13 KEY Question 26 Review
TEKS Econ: Benefits of Global Commerce
C
Correct Answer
unnecessary waste
TSIA2 Explanation
The original sentence uses three synonyms in a row: "unnecessary," "completely unneeded," and "superfluous." The phrase "unnecessary waste" conveys the full meaning clearly without clutter.
TSIA2 Strategy • The Redundancy Razor
On TSIA2 conciseness items, the shortest grammatically correct choice that preserves meaning is almost always the correct answer. Strip repetitive adjectives that repeat the same idea.
DAY 14 Q27 of 30 • Trade Barriers
TSIA2 Editing: Colon Usage
(1) Protectionist trade policies deploy three primary statutory mechanisms tariffs on imports, quotas limiting specific foreign commodities, and absolute embargoes.
Which revision correctly uses a colon to introduce the list in sentence 1?
A. mechanisms: tariffs on imports, quotas
B. mechanisms tariffs on: imports, quotas
C. mechanisms, tariffs on imports: quotas
D. mechanisms; tariffs on imports: quotas
DAY 14 KEY Question 27 Review
TEKS Econ: Tariffs, Quotas & Embargoes
A
Correct Answer
mechanisms: tariffs on imports, quotas
TSIA2 Explanation
A colon must be preceded by a complete independent clause ("Protectionist trade policies deploy three primary statutory mechanisms"). A colon introduces a list that directly explains or illustrates the preceding clause.
TSIA2 Strategy • The Independent Pre-Colon Check
Test the words before the colon: can they stand alone as a complete sentence? "Protectionist trade policies deploy three primary statutory mechanisms." Yes! Follow it with a colon to introduce the items.
DAY 14 Q28 of 30 • Free Trade Pacts
TSIA2 Revising: Sentence Placement
(1) The United States-Mexico-Canada Agreement (USMCA) established modernized trade frameworks across North America. (2) Cross-border industrial supply chains depend on predictable zero-tariff schedules. (3) Texas border ports, especially in Laredo and El Paso, facilitate billions in bilateral trade weekly. (4) [Sentence to insert: By dismantling regional barriers, this trilateral treaty dramatically accelerated logistics between Texas logistics hubs and Mexican factories.]
Where should the sentence above be placed to maximize coherence?
A. Before sentence 1
B. Immediately after sentence 1
C. Immediately after sentence 2
D. Immediately after sentence 3
DAY 14 KEY Question 28 Review
TEKS Econ: Free Trade Treaties & USMCA in Texas
B
Correct Answer
Immediately after sentence 1
TSIA2 Explanation
The phrase "this trilateral treaty" refers directly to the "United States-Mexico-Canada Agreement" named in sentence 1. It bridges the national treaty (sentence 1) to the supply chains and Texas border ports discussed in sentences 2 and 3.
TSIA2 Strategy • The Noun-Reference Anchor
Identify the noun anchor: "this trilateral treaty." A treaty between three nations was just introduced in sentence 1 (US, Mexico, Canada). Anchor the sentence directly after its referent.
DAY 15 Q29 of 30 • Financial Literacy
TSIA2 Reading: Vocabulary in Context
Financial advisors emphasize the exponential wealth-building power of compound interest. In contrast to simple interest, which yields returns solely on the initial principal, compound interest calculates dividends on both the accumulated interest and the original deposit, allowing personal savings portfolios to accelerate dramatically over time.
As used in the passage, the word "principal" most nearly refers to:
A. an administrative official supervising an educational institution
B. the chief ethical standard governing business transactions
C. the initial capital sum invested prior to accrued interest
D. the annual percentage rate assessed on credit obligations
DAY 15 KEY Question 29 Review
TEKS Personal Financial Literacy: Compound Interest
C
Correct Answer
the initial capital sum invested prior to accrued interest
TSIA2 Explanation
The text contrasts simple interest (calculated on the initial principal) with compound interest (calculated on accumulated interest AND "the original deposit"). This context clarifies that "principal" means the original starting investment.
TSIA2 Strategy • The Synonym Mirror
Look for parallel expressions later in the sentence. The phrase "the original deposit" mirrors and defines "the initial principal." Also watch for homophone traps (school principal vs. financial principal).

C. to pay your monthly balances on time promptly
D. monthly balances must be paid on time
DAY 15 KEY Question 30 Review
TEKS Personal Financial Literacy: Credit Scores
A
Correct Answer
paying monthly balances on time
TSIA2 Explanation
The sentence features a three-item compound gerund object following the verb "requires": 1) "reviewing credit reports," 2) "keeping credit utilization," and 3) "paying monthly balances." Option A maintains parallel grammatical structure.
TSIA2 Strategy • The Parallelism Rhythm Check
Read the list aloud focusing on verb endings: "reviewing..., keeping..., paying..." Any shift to an infinitive ("to pay") or full clause ("you should pay") breaks grammatical harmony.
