REFERENCE TEXT (1 OF 3)
Latin America - Economic Activity
Paragraphs 1 – 2
[Paragraph 1: Overview & Economic Shift]
[1] Latin America has a wealth of natural resources. [2] Those resources support a broad range of economic activities. [3] In the past, the economies of most Latin American countries were based largely on agriculture. [4] While agriculture is still crucial, today the region is working towards developing more manufacturing and service industries throughout the area.
[Paragraph 2: Subsistence Farming & Livestock]
[5] The most widespread economic activities of Latin America are livestock raising and subsistence farming. [6] Subsistence farmers usually only grow enough food to feed their families. [7] Good weather may sometimes allow them to produce a crop surplus. [8] They can then sell or barter their extra food for other things they need. [9] But surpluses are rare. [10] As a result, subsistence farmers are generally poor. [11] The most important crops grown by subsistence farmers are usually corn, potatoes, and beans.
Numbers [1]–[11] identify sentences for TSIA2 revising and editing items.
REFERENCE TEXT (2 OF 3)
Latin America - Economic Activity
Paragraphs 3 – 4
[Paragraph 3: Minerals & Energy Resources]
[12] The Europeans who first came to Latin America wanted its mineral wealth. [13] They were interested mainly in mining silver and gold. [14] Later, people mined copper, uranium, and other minerals as well. [15] Most of these metals are found in the Andes Mountains. [16] Today Latin America is better known for its energy resources. [17] This region has about 12 percent of the world’s petroleum, or oil supply. [18] Large oil deposits have been found in Mexico and Venezuela. [19] Latin American rivers are another source of energy. [20] Dams on rivers in Brazil and Paraguay produce large amounts of hydroelectric power.
[Paragraph 4: Commercial Farming & Ranching]
[21] Farming and ranching are important all across Latin America. [22] One of the most important commercial farming crops is coffee. [23] Coffee beans are grown on large plantations in Brazil, Colombia, and across Central America. [24] Other important crops from the region include bananas and sugarcane. [25] Ranchers raise mostly sheep and cattle. [26] The largest cattle ranches can be found on the Pampas of Argentina.
Numbers [12]–[26] denote sentences on mineral, energy, and commercial agriculture.
REFERENCE TEXT (3 OF 3)
Latin America - Economic Activity
Paragraphs 5 – 6
[Paragraph 5: Forestry]
[27] Forestry is another major industry. [28] Many types of trees are harvested from Latin American forests. [29] This wood is used for building materials and fuel. [30] It is also used to make products such as furniture and musical instruments.
[Paragraph 6: Services, Manufacturing & Barriers]
[31] Service industries and manufacturing have grown rapidly in Latin America. [32] The most important industry in the Caribbean islands is tourism, while Venezuela, Mexico, and Brazil are among the industrial leaders of the region. [33] Workers in the industrial areas of Latin America produce iron and steel, cars, textiles, cement, chemicals, and electrical goods. [34] Many countries in the region do not have industrial economies though. [35] They lack the money, skilled labor, and the transportation systems to build industries. [36] Rugged mountains and thick tropical vegetation create physical barriers to movement of both people and resources.

READING COMPREHENSION Question 1 of 10
Skill: Central Idea & Purpose
Which of the following statements best expresses the main idea of the entire passage?
A. Latin America’s economy relies almost exclusively on mineral deposits such as silver, gold, and uranium found in the Andes Mountains.
B. While agriculture remains widespread, Latin America possesses diverse natural resources and is working toward expanded industrial development.
C. Geographic obstacles have entirely halted commercial agriculture and factory growth across every country in South America.
D. Tourism in the Caribbean islands is the single largest generator of wealth across the entire Latin American region.
Consider the overarching focus of all six paragraphs. Advance to view Answer & Strategy →
ANSWER & STRATEGY Question 1 Review
Correct Answer: B
Detailed Rationale
Paragraph 1 establishes the thesis: Latin America has vast natural resources supporting diverse activities, shifting from agriculture toward manufacturing and services. The succeeding paragraphs catalog agriculture, minerals, energy, forestry, and modern industries.
Why Other Choices Fail:
A & D: Narrow isolated details (minerals or tourism).
C: Makes an extreme claim ("entirely halted") contradicted by text.
TSIA2 STRATEGY
The "Umbrella Rule"
On TSIA2 Central Idea items, incorrect choices are usually too narrow (one paragraph only) or too extreme (words like "always," "never," or "exclusively").
Action Step: Choose the option that functions as an "umbrella"—broad enough to cover every paragraph without adding extreme claims.

READING COMPREHENSION Question 2 of 10
Skill: Words in Context
Context (Sentences 7–8): "Good weather may sometimes allow them to produce a crop surplus. They can then sell or barter their extra food for other things they need."
As used in sentence 7, the word "surplus" most nearly means:
A. A rare variety of seed bred for harsh weather conditions
B. An amount or quantity greater than what is strictly needed
C. A financial tax imposed by governing authorities on harvested crops
D. A severe shortage caused by unexpected weather patterns
Notice the clue in sentence 8: "extra food." Advance to view Answer & Strategy →
ANSWER & STRATEGY Question 2 Review
Correct Answer: B
Detailed Rationale
The sentence immediately following provides direct context: "They can then sell or barter their extra food for other things they need." The phrase "extra food" defines "surplus" as an amount exceeding family survival needs.
Why Other Choices Fail:
A & C: Neither seeds nor taxes fit the context of barter or food.
D: Represents the opposite meaning (shortage instead of extra).
TSIA2 STRATEGY
The Substitution Method
Never rely strictly on dictionary definitions. TSIA2 tests how words function inside the sentence's surrounding architecture.
Action Step: Cross out the tested word, insert each answer choice in its place, and check whether the following sentence confirms the substituted meaning.

Question 2 of 10 Complete Next: Paired Comparison & Inference →
READING COMPREHENSION Question 3 of 10
Skill: Comparative Analysis
Based on paragraphs 2 and 4, how does commercial farming primarily differ from subsistence farming in Latin America?
A. Commercial farming takes place on large plantations to produce cash crops for trade, while subsistence farming focuses on feeding a single family.
B. Commercial farming occurs exclusively in the Andes Mountains, whereas subsistence farming is confined to coastal Caribbean islands.
C. Subsistence farmers focus solely on livestock like cattle and sheep, whereas commercial farmers grow only potatoes and beans.
D. Subsistence farming generates major export profits for countries like Brazil, whereas commercial farming yields chronic poverty.
Compare Sentence 6 with Sentences 22–24. Advance to view Answer & Strategy →
ANSWER & STRATEGY Question 3 Review
Correct Answer: A
Detailed Rationale
Paragraph 2 explicitly states that subsistence farmers "only grow enough food to feed their families" and are generally poor. In contrast, Paragraph 4 describes commercial crops (coffee, bananas, sugarcane) grown on "large plantations" for broad trade.
Why Other Choices Fail:
B: Geography is wrong (minerals are in Andes; coffee in Brazil/Colombia).
C & D: Directly reverses crop and economic relationships in the text.
TSIA2 STRATEGY
Parallel Contrast Checks
When TSIA2 asks you to distinguish between two concepts, construct a 2-column mental chart using exact textual details.
Action Step: Check both halves of each option. Test makers often make the first half true and the second half subtly incorrect to lure hasty readers.

Question 3 of 10 Complete Next: Text Evidence Analysis →
READING COMPREHENSION Question 4 of 10
Skill: Supporting Evidence
According to paragraph 6, which combination of factors creates a significant barrier to industrialization for several Latin American countries?
A. A shortage of natural rivers for hydroelectric energy and an overabundance of timber
B. Lack of capital, shortage of skilled workers, inadequate transport, and rugged physical terrain
C. Strict international bans on oil extraction in Mexico and Venezuela
D. Severe declines in international tourist visits to Caribbean island destinations
Look specifically at Sentences 35 and 36. Advance to view Answer & Strategy →
ANSWER & STRATEGY Question 4 Review
Correct Answer: B
Detailed Rationale
Sentence 35 explicitly lists three socio-economic obstacles: "They lack the money, skilled labor, and the transportation systems to build industries." Sentence 36 adds physical obstacles: "Rugged mountains and thick tropical vegetation create physical barriers." Choice B synthesizes both sentences accurately.
Why Other Choices Fail:
A, C, D: These options invent facts not in the passage or contradict text confirming abundant rivers and oil reserves.
TSIA2 STRATEGY
Direct Textual Anchoring
TSIA2 informational reading questions test explicit recall and synthesis. Avoid outside knowledge or speculative reasoning.
Action Step: Locate the exact sentence in the passage and match keywords (e.g., "lack," "barriers," "mountains"). The correct answer will be a faithful paraphrase.

REVISING: ESSAY REVISION Question 5 of 10
Skill: Sentence Combining & Conciseness
Original Sentences 1 & 2: "[1] Latin America has a wealth of natural resources. [2] Those resources support a broad range of economic activities."
Which choice is the most effective and concise way to combine sentences 1 and 2?
A. Latin America has a wealth of natural resources, and those resources support a broad range of economic activities.
B. Latin America has a wealth of natural resources that support a broad range of economic activities.
C. Because Latin America has a wealth of natural resources, so they support a broad range of economic activities.
D. Supporting a broad range of economic activities, a wealth of natural resources is possessed by Latin America.
Look for the choice eliminating repetitive nouns without adding awkward passive voice. Advance to view Answer & Strategy →
ANSWER & STRATEGY Question 5 Review
Correct Answer: B
Detailed Rationale
Choice B uses the relative pronoun "that" to smoothly connect the two independent clauses, eliminating the clumsy repetition of "those resources." It preserves the active voice and maintains clear, direct syntax.
Why Other Choices Fail:
A: Repetitive and wordy (keeps "those resources").
C: Unacceptable double-conjunction ("Because... so...").
D: Weak passive voice and misplaced modifier structure.
TSIA2 STRATEGY
Economy of Language
On TSIA2 Revising questions, when multiple answer choices are grammatically correct, the most concise option that preserves clarity is almost always the intended answer.
Action Step: Beware of redundant phrases, awkward passive constructions ("is possessed by"), and double cause-and-effect connectors.

REVISING: ESSAY REVISION Question 6 of 10
Skill: Transitional Logic
Original Sentence 34: "Many countries in the region do not have industrial economies though."
Which revision of sentence 34 best improves the academic tone and transition between paragraphs?
A. In conclusion, many countries in the region do not have industrial economies though.
B. However, many countries in the region still lack industrial economies.
C. Furthermore, many countries in the region do not have industrial economies though.
D. For example, industrial economies are not had by many countries in the region.
Notice the contrast with Sentence 33's description of successful manufacturing. Advance to view Answer & Strategy →
ANSWER & STRATEGY Question 6 Review
Correct Answer: B
Detailed Rationale
Sentence 33 highlights industrial leaders (Mexico, Brazil, Venezuela producing steel and cars). Sentence 34 introduces a contrast: many other nations cannot industrialize. Ending with informal "though" is colloquial; opening with "However" establishes formal academic transition.
Why Other Choices Fail:
A & C: Incorrect transitional logic and retains awkward trailing "though."
D: Misuses "For example" and creates clumsy passive voice ("are not had").
TSIA2 STRATEGY
Transition Function Test
Identify the relationship between ideas before looking at the choices:
• Contrast: However, Nevertheless, In contrast
• Addition: Furthermore, In addition, Moreover
• Cause/Effect: Therefore, Consequently, As a result

REVISING: ESSAY REVISION Question 7 of 10
Skill: Relevant Supporting Evidence
Context: "[20] Dams on rivers in Brazil and Paraguay produce large amounts of hydroelectric power."
The author wants to add a relevant example immediately after sentence 20. Which choice best accomplishes this goal?
A. For example, the Itaipu Dam on the Paraná River between Brazil and Paraguay is one of the world's largest clean electricity producers.
B. In fact, commercial tourists frequently travel down South American rivers on luxury cruise liners during summer months.
C. Similarly, coal was widely mined in European nations to power locomotive train engines during the Industrial Revolution.
D. Therefore, ranchers in Argentina require hundreds of square miles of open pasture to graze herds of cattle.
Which choice provides concrete evidence supporting hydroelectric power in Brazil/Paraguay? Advance to view Answer & Strategy →
ANSWER & STRATEGY Question 7 Review
Correct Answer: A
Detailed Rationale
Sentence 20 specifically discusses dams on rivers in Brazil and Paraguay producing hydroelectricity. Choice A provides a precise, factual, real-world example (the Itaipu Dam) that directly substantiates that exact claim without introducing off-topic tangents.
Why Other Choices Fail:
B: River tourism diverts attention away from electricity generation.
C: Mentions European coal history, outside the passage's geographic focus.
D: Belongs in paragraph 4 with ranching, not paragraph 3 with energy.
TSIA2 STRATEGY
Targeted Content Relevance
When asked where to add a sentence, TSIA2 tests your ability to maintain topical coherence.
Action Step: Check the immediate preceding sentence. The inserted detail must act as a direct extension, naming specific entities or data aligned with that sentence.

Skill: Comma Splices & Run-on Sentences
Draft Sentence: "Large oil deposits have been found in Venezuela, these reserves supply roughly 12 percent of world petroleum."
Which revision best corrects the punctuation error in the underlined portion?
A. NO CHANGE
B. Large oil deposits have been found in Venezuela, these reserves, supplying roughly 12 percent of world petroleum.
C. Large oil deposits have been found in Venezuela; and these reserves supply roughly 12 percent of world petroleum.
D. Large oil deposits have been found in Venezuela, and these reserves supply roughly 12 percent of world petroleum.
Check the clause boundaries: are there two independent clauses joined only by a comma? Advance to view Answer & Strategy →
ANSWER & STRATEGY Question 8 Review
Correct Answer: D
Detailed Rationale
The original draft contains two complete independent clauses joined only by a comma—a textbook comma splice. Choice D correctly repairs this error by pairing the comma with the coordinating conjunction "and" (Comma + FANBOYS rule).
Why Other Choices Fail:
A: Retains the illegal comma splice.
B: Creates a sentence fragment in the second clause.
C: Redundant punctuation (never use a semicolon AND a conjunction).
TSIA2 STRATEGY
The Three Fixes for Splices
When you see two complete independent thoughts, TSIA2 accepts three standard structural fixes:
1. Period: [Clause 1]. [Clause 2].
2. Semicolon: [Clause 1]; [Clause 2].
3. Comma + FANBOYS: [Clause 1], and [Clause 2].

Test Sentence: "The collection of mineral deposits found along the peaks of the Andes Mountains were valued by European explorers for centuries."
Which choice correctly edits the underlined verb phrase to maintain proper agreement?
A. NO CHANGE
B. was valued
C. are valued
D. were being valued
Locate the true head subject: What was valued? Advance to view Answer & Strategy →
ANSWER & STRATEGY Question 9 Review
Correct Answer: B
Detailed Rationale
The grammatical subject is the singular noun "collection." The prepositional phrases "of mineral deposits" and "along the peaks of the Andes Mountains" are intervening modifiers that do not alter the singular subject. A singular past-tense subject requires "was valued."
Why Other Choices Fail:
A & D: Use plural verb "were," mistakenly agreeing with "deposits" or "Mountains."
C: Present tense "are" contradicts the past time-frame ("for centuries").
TSIA2 STRATEGY
Ignore the "Intervening Fluff"
TSIA2 test questions deliberately place long prepositional phrases with plural nouns directly before the verb to deceive the ear.
Action Step: Cross out every prepositional phrase between the lead noun and the verb. Read the bare subject directly with the verb: "The collection... was valued."

Question 9 of 10 Complete Next: Parallel Structure →
EDITING: CONVENTIONS Question 10 of 10
Skill: Parallel Structure in Series
Draft Sentence (adapted from Sentence 33): "Workers in industrial areas manufacture automobiles, refine crude petroleum, and the production of textiles is conducted."
Which choice produces the most grammatically parallel list of actions?
A. NO CHANGE
B. to produce textiles
C. produce textiles
D. producing textiles on a daily basis
Compare verb forms: "manufacture...", "refine...", and "______..." Advance to view Answer & Strategy →
ANSWER & STRATEGY Question 10 Review
Correct Answer: C
Detailed Rationale
Items in a grammatical series governed by the subject "Workers" must share identical syntactic structure:
[Verb 1: manufacture] automobiles,
[Verb 2: refine] crude petroleum, and
[Verb 3: produce] textiles. Choice C maintains active base-form verbs in strict parallel alignment.
Why Other Choices Fail:
A: Shifts abruptly to an independent passive clause.
B: Shifts to an infinitive phrase ("to produce").
D: Shifts to a participle ("producing").
TSIA2 STRATEGY
The Pattern Match Test
Parallel structure items always feature a coordinate conjunction (and, or, but) joining two or more elements.
Action Step: Underline the verbs leading up to the conjunction. Whatever grammatical pattern items 1 and 2 establish, item 3 must mirror exactly.
