DAY 1 • Q1 East Texas Piney Woods
"The Texas Piney Woods, who cover the eastern border of the state, are home to dense forests of longleaf pines and historic cypress swamps."
What is the correct way to write the underlined word?
A who
B whom
C which
D whose
Skill: Relative Pronoun Usage Next slide reveals key
DAY 1 • Q1 KEY Verified Answer
C
Use relative pronoun "which"
"The Texas Piney Woods, which cover the eastern border..."
Explanation
The Piney Woods is a geographic location and non-human entity. The relative pronoun who is reserved strictly for people. Use which for places, ecosystems, or non-restrictive objects.
Geographic Clue & Rule
Rule: Person = *Who/Whom*. Non-Person = *Which/That*. Since the Piney Woods is a swampy forest region, "which" is the correct connector.
Ensure this rule is transcribed in your Student Tracker!
DAY 1 • Q2 Trans-Pecos Mountains
"The Trans-Pecos region is the most arid part of Texas; therefore, it contains the stunning, rugged peaks of the Chisos Mountains."
Which transition word should replace the underlined word to fix the logical error?
A consequently
B however
C furthermore
D similarly
Skill: Conjunctive Adverbs (Transition Words) Next slide reveals key
DAY 1 • Q2 KEY Verified Answer
B
Use contrast transition "however"
"...most arid part of Texas; however, it contains..."
Explanation
"Therefore" indicates a direct cause-and-effect relationship, which is incorrect. An arid climate does not cause mountains to exist. Instead, the word however introduces an unexpected contrast—a dry desert that nevertheless boasts magnificent high-elevation peaks.
Geographic Clue & Rule
Rule: Evaluate the relationship between independent clauses before selecting transitions. Use contrast markers like *however* when ideas contradict expectations.
Log your correct answer and the contrast transition rule on Page 1!
DAY 2 • Q1 Edwards Aquifer Basin
"The Edwards Aquifer, along with several surrounding limestone river basins, provide fresh drinking water to millions of Texans."
What change, if any, should be made to the underlined verb?
A change provide to provides
B change provide to providing
C change provide to has provided
D Make no change
Skill: Subject-Verb Agreement with Intervening Phrases Next slide reveals key
DAY 2 • Q1 KEY Verified Answer
A
Change "provide" to "provides"
"The Edwards Aquifer... provides fresh drinking water..."
Explanation
The grammatical subject is The Edwards Aquifer, which is singular. The intervening parenthetical phrase "along with several surrounding limestone river basins" does not change the subject to plural. Therefore, we must use the singular verb "provides."
Geographic Clue & Rule
Rule: To find the subject, temporarily cross out words starting with *along with*, *as well as*, or *together with*. What's left dictates if the verb is singular or plural.
Write down the intervening phrase trick in your Tracker.
DAY 2 • Q2 Karst Topography
"Because karst topography is highly porous, surface water quickly sinks into the underground cave system, carrying their pollutants directly into the aquifer."
What change, if any, should be made to the underlined possessive pronoun?
A change their to its
B change their to there
C change their to it's
D Make no change
Skill: Pronoun-Antecedent Agreement Next slide reveals key
DAY 2 • Q2 KEY Verified Answer
A
Change plural "their" to singular "its"
"...surface water quickly sinks... carrying its pollutants..."
Explanation
The pronoun refers back to the antecedent surface water, which is a singular mass noun. Therefore, the possessive pronoun must also be singular. Since the water is non-human, the singular possessive its is required.
Geographic Clue & Rule
Rule: Pronouns must agree in number with their antecedents. Watch out for mass nouns like *water*, *runoff*, or *vegetation*—they are singular and require "its."
Record your Day 2 findings on your tracker. Let's move to Day 3!
DAY 3 • Q1 Spindletop Boom
"In 1901, a massive geyser of oil was struck by drilling crews at Spindletop Hill near Beaumont, which initiated the modern petroleum age."
What is the most effective way to revise this sentence to use the strong active voice?
A In 1901, drilling crews at Spindletop Hill near Beaumont struck a massive geyser of oil, initiating the modern petroleum age.
B A massive geyser of oil near Beaumont at Spindletop Hill was struck in 1901, and the modern petroleum age was initiated.
C Initiating the modern petroleum age, in 1901 drilling crews near Beaumont at Spindletop Hill were striking oil.
D Struck by drilling crews in 1901, a massive geyser of oil near Beaumont at Spindletop Hill initiated the petroleum age.
Skill: Sentence Revision for Active Voice & Clarity Next slide reveals key
DAY 3 • Q1 KEY Verified Answer
A
Revise to highlight active subjects first
"...drilling crews... struck a massive geyser of oil, initiating..."
Explanation
The original sentence is written in the passive voice ("was struck by..."). Option A corrects this by making drilling crews (the active subject) perform the action (struck) on the object (oil). This structure is much punchier and more direct.
Geographic Clue & Rule
Rule: Active voice is always preferred on the English I EOC. Ensure the actor (subject) is placed immediately before the action (verb) to drive the sentence forward.
Ensure the difference between passive and active voice is noted on your worksheet!
DAY 3 • Q2 Boomtown Boom
"Spindletop transformed the regional economy overnight, thousands of workers flooded into the tiny town in search of wealth."
What is the correct way to rewrite this run-on sentence and fix the comma splice?
A ...overnight, and thousands...
B ...overnight thousands...
C ...overnight; and thousands...
D ...overnight, because thousands...
Skill: Eliminating Comma Splices Next slide reveals key
DAY 3 • Q2 KEY Verified Answer
A
Fix comma splice with a coordinating conjunction
"...economy overnight, and thousands of workers..."
Explanation
A comma splice occurs when two independent clauses (complete sentences) are joined with only a comma. Adding the coordinating conjunction and after the comma establishes a compound sentence and corrects the run-on.
Geographic Clue & Rule
Rule: Connect independent clauses using a semicolon, or a comma plus one of the seven FANBOYS coordinating conjunctions (*for, and, nor, but, or, yet, so*).
Log your correct answers. Let's move on to Day 4!
DAY 4 • Q1 Galveston Hurricane 1900
"After the devastating hurricane of 1900 destroyed much of Galveston the city constructed a massive concrete seawall to protect residents from future storm surges."
What punctuation change should be made to this sentence?
A Insert a comma after Galveston
B Insert a comma after seawall
C Insert a semicolon after Galveston
D Make no change
Skill: Commas after Introductory Dependent Clauses Next slide reveals key
DAY 4 • Q1 KEY Verified Answer
A
Insert a comma after introductory clause
"After... destroyed much of Galveston, the city..."
Explanation
The sentence begins with an adverbial dependent clause introduced by the subordinating conjunction "After." When a dependent clause is placed at the start of a sentence, a comma must separate it from the independent clause that follows.
Geographic Clue & Rule
Rule: *Dependent, Independent.* Put a comma after an introductory phrase/clause if it tells when, where, why, or how the main action occurs.
Keep your tracker fully populated with this introductory comma rule.
DAY 4 • Q2 City Elevating Projects
"The 17-foot seawall successfully mitigated storm surges during subsequent hurricanes. As a result, developers raised the elevation of the entire city by pumping in sand from the gulf."
Which transition should replace the underlined phrase to show the correct logical addition?
A On the other hand
B In addition to this defense
C To illustrate this point
D Nevertheless
Skill: Improving Sentences with Logical Transitions Next slide reveals key
DAY 4 • Q2 KEY Verified Answer
B
Select transitional addition marker
"...subsequent hurricanes. In addition to this defense, developers..."
Explanation
"As a result" implies raising the city's elevation was caused directly by the success of the seawall, which is logically flawed. Rather, raising the city was a secondary, distinct engineering initiative. Option B beautifully connects the two measures as additive defenses.
Geographic Clue & Rule
Rule: Ensure transitions accurately represent relationships: contrast, cause-and-effect, sequence, or addition. Avoid assuming consecutive events always have a causal link.

DAY 5 • Q1 Borderlands Cultural Hybrid
Sentence 1: The Texas-Mexico border region represents a unique cultural hybrid.
Sentence 2: This region blends food, language, and architectural styles from both nations.
What is the most effective way to combine these two sentences?
A Representing a unique cultural hybrid, the Texas-Mexico border region blends food, language, and architectural styles from both nations.
B The Texas-Mexico border region represents a unique cultural hybrid, but it blends food, language, and architectural styles from both nations.
C Because it blends food, language, and architectural styles from both nations, the Texas-Mexico border region is represented as a hybrid.
D The Texas-Mexico border region represents a unique cultural hybrid; although it blends food, language, and architectural styles.
Skill: Sentence Combining with Participial Phrases Next slide reveals key
DAY 5 • Q1 KEY Verified Answer
A
Combine sentences using a participial modifier
"Representing a unique cultural hybrid, the Texas-Mexico border..."
Explanation
Option A is the most concise and elegant combination. It converts Sentence 1 into an introductory participial phrase ("Representing a unique cultural hybrid") that naturally modifies the subject of the main clause, avoiding redundant nouns or awkward clunky subordinations.
Geographic Clue & Rule
Rule: Eliminate repetition by condensing secondary descriptions into dynamic "-ing" or "-ed" opening phrases. Place the main actor right after the comma.
Log this advanced combination trick on your tracker!
DAY 5 • Q2 Rio Grande Trade Co-ops
"International bridges support the two country's shared trade agreements and daily border crossings."
What is the correct way to write the underlined possessive noun?
A countries
B countries'
C countrys
D Make no change
Skill: Plural Possessive Apostrophe Rules Next slide reveals key
DAY 5 • Q2 KEY Verified Answer
B
Change to plural possessive "countries'"
"...support the two countries' shared trade..."
Explanation
The sentence specifies "two" nations. Therefore, the noun must be plural (countries). Because the trade agreements belong to both countries, it must also be possessive. For regular plural nouns, establish possession by placing an apostrophe after the *s* (countries').
Geographic Clue & Rule
Rule: Singular possessive: *country's* (one country). Plural possessive: *countries'* (multiple countries). Since the bridge links the USA and Mexico, use the plural possessive.
Log your correct choices. Halfway through Week 1!
DAY 6 • Q1 Caprock Escarpment
"The Caprock Escarpment is a dramatic transition zone, it separates the flat Llano Estacado from the lower rolling plains."
What is the correct way to write this sentence to eliminate the comma splice?
A ...dramatic transition zone that separates the flat Llano Estacado...
B ...dramatic transition zone, separates the flat Llano Estacado...
C ...dramatic transition zone; separating the flat Llano Estacado...
D ...dramatic transition zone, and which separates the flat Llano Estacado...
Skill: Comma Splice Correction with Relative Clauses Next slide reveals key
DAY 6 • Q1 KEY Verified Answer
A
Use a relative pronoun "that"
"...a dramatic transition zone that separates..."
Explanation
The comma splice in the original sentence occurred by joining two independent clauses with only a comma. By introducing the relative pronoun that, we convert the second clause into a subordinate clause, seamlessly correcting the run-on.
Geographic Clue & Rule
Rule: Eliminate comma splices by subordinating one of the sentences with relative pronouns like *which, who, that, where, whose*. This creates a fluid complex sentence.
Log your results. Let's look at Day 6, Question 2.
DAY 6 • Q2 High Plains Climate
"Severe winds blow continual across the High Plains, carving deep canyons into the layered sedimentary rock."
What change should be made to the underlined word?
A change continual to continually
B change continual to continuous
C change continual to more continual
D Make no change
Skill: Adjective vs. Adverb Modifier Usage Next slide reveals key
DAY 6 • Q2 KEY Verified Answer
A
Change to adverb form "continually"
"Severe winds blow continually across..."
Explanation
The word "continual" is an adjective, but it is modifying the action verb blow. To modify a verb, you must use an adverb rather than an adjective. Adding the "-ly" suffix converts it to the adverb "continually."
Geographic Clue & Rule
Rule: Adjectives modify nouns (e.g., *continual wind*); adverbs modify verbs, adjectives, or other adverbs (e.g., *blow continually*).
Log your results. Let's move to Day 7!
DAY 7 • Q1 Texas Triangle Megalopolis
"The highly urbanized region known as the texas triangle contains the metropolitan areas of Houston, Dallas, Austin, and San Antonio."
What is the correct way to write the underlined geographic name?
A Texas triangle
B texas Triangle
C Texas Triangle
D Make no change
Skill: Capitalizing Proper Geographic Nouns Next slide reveals key
DAY 7 • Q1 KEY Verified Answer
C
Capitalize "Texas Triangle"
"...region known as the Texas Triangle contains..."
Explanation
The "Texas Triangle" is a specific named geographical region, making it a proper noun. Proper nouns, including all major words within official region names, must be capitalized.
Geographic Clue & Rule
Rule: Official geographical terms and regional designations (such as the *Great Plains*, *Texas Triangle*, or *West Coast*) are capitalized, while general directions are not.
Log your correct answers. Let's check Day 7, Question 2.
DAY 7 • Q2 Megacity Growth
"Rapid population growth in the region will inevitably effect water reserves and transportation infrastructure over the next decade."
What change, if any, should be made to the underlined word?
A change effect to affect
B change effect to affects
C change effect to effective
D Make no change
Skill: Homophones (Affect vs. Effect) Next slide reveals key
DAY 7 • Q2 KEY Verified Answer
A
Change "effect" to "affect"
"...will inevitably affect water reserves..."
Explanation
In this sentence, the context demands an action verb meaning "to influence or act upon." The word affect is almost always a verb, whereas effect is almost always a noun meaning "a result."
Geographic Clue & Rule
Rule: **A**ffect is an **A**ction (Verb). **E**ffect is the **E**nd result (Noun). Use *affect* as the verb after helper words like "will," "would," or "should."
Log your correct answers. Let's move to Day 8!
DAY 8 • Q1 West Texas Wind Farms
"West Texas is ideal for wind power generation, because it features wide open spaces and flat, elevated plateaus."
What change, if any, should be made to the punctuation of this sentence?
A Delete the comma before because
B Change the comma to a semicolon
C Insert a comma after generation
D Make no change
Skill: Eliminating Unnecessary Commas with Dependent Clauses Next slide reveals key
DAY 8 • Q1 KEY Verified Answer
A
Delete the comma before "because"
"West Texas is ideal for wind power generation because it features..."
Explanation
When a dependent adverbial clause starting with a subordinating conjunction like "because" follows an independent clause, a comma should not be used to separate them.
Geographic Clue & Rule
Rule: *Independent + Dependent* requires no comma (e.g., *I slept because I was tired*). Only *Dependent + Independent* requires a comma.
Verify this rule is in your Student Tracker!
DAY 8 • Q2 Power Grid Expansion
"Standing hundreds of feet tall, engineers construct wind turbines to capture strong, high-altitude breezes."
What is the best way to revise this sentence to correct a misplaced modifier?
A Engineers construct wind turbines, standing hundreds of feet tall, to capture strong, high-altitude breezes.
B Standing hundreds of feet tall, wind turbines are constructed by engineers to capture strong breezes.
C To capture strong, high-altitude breezes, engineers standing hundreds of feet tall construct wind turbines.
D Engineers construct wind turbines standing hundreds of feet tall to capture strong breezes.
Skill: Correcting Misplaced and Dangling Modifiers Next slide reveals key
DAY 8 • Q2 KEY Verified Answer
B
Align the introductory modifier to "wind turbines"
"Standing hundreds of feet tall, wind turbines are..."
Explanation
In the original sentence, the introductory phrase "Standing hundreds of feet tall" incorrectly modified "engineers," implying the engineers themselves are giant towers. Option B places the actual object being described (wind turbines) directly after the introductory modifier.
Geographic Clue & Rule
Rule: Keep introductory describing phrases directly next to the noun they are intended to describe, or restructure the sentence completely to restore logic.
End of Week 1! Log your final answers on Page 1.
DAY 9 • Q1 Dust Bowl Dust Storms
"Blown by relentless winds, the 1930s saw massive clouds of black dust lift the topsoil of the Texas Panhandle."
What is the correct way to write this sentence to correct the dangling modifier?
A Blown by relentless winds, the topsoil of the Texas Panhandle was lifted into massive clouds of black dust during the 1930s.
B Blown by relentless winds, massive clouds of black dust lifted the 1930s topsoil of the Texas Panhandle.
C Standing in relentless winds, the topsoil was blown into massive clouds of black dust during the 1930s.
D Make no change
Skill: Resolving Dangling Modifiers Next slide reveals key
DAY 9 • Q1 KEY Verified Answer
A
Align the introductory modifier to "the topsoil"
"Blown by relentless winds, the topsoil of..."
Explanation
In the original sentence, the introductory phrase "Blown by relentless winds" incorrectly modified "the 1930s," which is a decade and cannot be physically blown. Option A corrects this by placing the actual noun modified (the topsoil) immediately after the comma.
Geographic Clue & Rule
Rule: Dangling modifiers occur when the subject being described is missing or displaced. The noun right after the introductory comma must be the target of the describing phrase.
Log your correct answers on Page 2.
DAY 9 • Q2 Soil Conservation Practices
"To combat soil erosion, farmers learned to plant windbreaks, practice contour plowing, and they rotated crops."
What change should be made to the underlined phrase to ensure parallel structure?
A change they rotated to rotating
B change they rotated to rotate
C change they rotated to to rotate
D Make no change
Skill: Maintaining Parallel Structure in Lists Next slide reveals key
DAY 9 • Q2 KEY Verified Answer
B
Change to base verb "rotate"
"...to plant windbreaks, practice contour plowing, and rotate crops."
Explanation
The sentence contains a series of actions following the helping infinitive "to": "to [plant] windbreaks, [practice] contour plowing, and [rotate] crops." Changing "they rotated" to the base verb "rotate" aligns perfectly with the list's parallel structure.
Geographic Clue & Rule
Rule: Items linked in a list must use the identical grammatical form: all base verbs, all gerunds (-ing), or all complete independent clauses.
Log your correct answers. Let's move to Day 10!
DAY 10 • Q1 Port of Houston Trade
"The Port of Houston handles billions of dollars of international commodities every year, such as: petroleum, grain, and heavy machinery."
What change should be made to the underlined colon in this sentence?
A Delete the colon after such as
B Move the colon to after commodities
C Change the colon to a semicolon
D Make no change
Skill: Rules of Colon Usage in Sentences Next slide reveals key
DAY 10 • Q1 KEY Verified Answer
A
Delete the colon after "such as"
"...international commodities every year, such as petroleum, grain..."
Explanation
Colons must only follow a complete independent clause. Inserting a colon directly after introductory phrases like "such as" or "including" disrupts sentence flow and is grammatically incorrect.
Geographic Clue & Rule
Rule: Never put a colon directly after a verb, a preposition, or transition phrases like *such as*.
Log your correct answers. Let's look at Day 10, Question 2.
DAY 10 • Q2 Petrochemical Channels
"The wide, dredged channel allows large container ships to navigate safely and without danger into the inland port."
What is the most effective way to revise the underlined phrase to eliminate redundancy?
A safely
B safely and in a non-dangerous manner
C safe and free from any hazardous danger
D Make no change
Skill: Eliminating Redundant and Repetitive Phrasing Next slide reveals key
DAY 10 • Q2 KEY Verified Answer
A
Select concise adverb "safely"
"...ships to navigate safely into the inland port."
Explanation
The phrase "safely and without danger" is redundant because "safely" inherently means without danger. Option A is the most direct and effective choice, communicating the complete meaning using fewer words.
Geographic Clue & Rule
Rule: Avoid combining words that mean the same thing (e.g., *safely* and *without danger*). Conciseness is key to earning top revising scores.
Log your correct answers. Let's move to Day 11!
DAY 11 • Q1 Hill Country Settlements
"In the mid-19th century, European immigrants settled the Texas Hill Country, built stone cottages, and establish unique cultural enclaves that persist today."
What change should be made to the underlined word?
A change establish to established
B change establish to will establish
C change establish to establishing
D Make no change
Skill: Maintaining Verb Tense Consistency Next slide reveals key
DAY 11 • Q1 KEY Verified Answer
A
Change to past tense "established"
"...built stone cottages, and established unique..."
Explanation
The sentence lists historical events that occurred in the "mid-19th century." The first two verbs in the parallel sequence are in the simple past tense (settled and built). The third verb must also be past tense (established).
Geographic Clue & Rule
Rule: Maintain consistent verb tenses within sentences describing historical periods. Avoid random transitions between past and present.
Track your answer and verb consistency rule. Onward!
DAY 11 • Q2 Tejano Cultural Blends
"The mixing together of German and Mexican music styles led to the creation of traditional Tejano accordion music."
Which word is the most precise and academic replacement for the underlined phrase?
A collision
B fusion
C gathering
D compilation
Skill: Selecting Precise Academic Vocabulary Next slide reveals key
DAY 11 • Q2 KEY Verified Answer
B
Select precise noun "fusion"
"The fusion of German and Mexican music..."
Explanation
"Mixing together" is informal and wordy. While "collision" implies conflict and "compilation" implies a simple collection, fusion precisely describes the seamless, creative blending of different cultural elements into a brand-new hybrid.
Geographic Clue & Rule
Rule: Swap out multi-word informal descriptions for singular, sophisticated academic vocabulary when revising text for formal publication.
Log your correct answers. Let's move to Day 12!
DAY 12 • Q1 Rio Grande Valley Agriculture
"A large fleet of agricultural trucks is scheduled to transport fresh citrus fruits from the Rio Grande Valley to northern markets."
What change, if any, should be made to the underlined verb?
A change is to are
B change is to were
C change is to being
D Make no change
Skill: Subject-Verb Agreement with Collective Nouns Next slide reveals key
DAY 12 • Q1 KEY Verified Answer
D
No change is needed
"A large fleet... is scheduled to..."
Explanation
The grammatical subject is fleet, which is a collective noun. Because the fleet acts as a single unified entity scheduling a task, it takes a singular verb (is). Do not be misled by the plural prepositional object "trucks."
Geographic Clue & Rule
Rule: Collective nouns (e.g., *fleet*, *group*, *herd*, *committee*) take singular verbs when acting as a single unit. Always verify the true noun subject!
Log your correct answers. Let's look at Day 12, Question 2.
DAY 12 • Q2 Valley Irrigation Needs
"The region has rich agricultural potential but receives low annual rainfall. Similarly, farmers rely heavily on irrigation systems fed by the Rio Grande."
Which transition should replace the underlined word to show the correct logical relationship?
A Consequently
B Nevertheless
C In contrast
D Make no change
Skill: Selecting Cause-and-Effect Transitions Next slide reveals key
DAY 12 • Q2 KEY Verified Answer
A
Use causal marker "Consequently"
"...low annual rainfall. Consequently, farmers rely heavily..."
Explanation
The relationship is direct cause-and-effect: low rainfall (cause) forces farmers to rely heavily on irrigation systems (effect). "Similarly" implies comparison, which is incorrect. Consequently is the logical connector.
Geographic Clue & Rule
Rule: Connect a problem and its physical solution using cause-and-effect transitional markers such as *consequently, therefore, thus, as a result,* or *hence*.
Log your correct answers. Let's move to Day 13!
DAY 13 • Q1 Silicon Hills Tech Sector
"Tech companies recruit skilled software engineers whom design cutting-edge semiconductor chips in the Austin metro area."
What change should be made to the underlined relative pronoun?
A change whom to who
B change whom to which
C change whom to whose
D Make no change
Skill: Case of Relative Pronouns (Who vs. Whom) Next slide reveals key
DAY 13 • Q1 KEY Verified Answer
A
Change "whom" to subject relative "who"
"...software engineers who design cutting-edge..."
Explanation
The relative pronoun acts as the grammatical subject performing the action of the verb design in the relative clause. Thus, we must use the subjective case pronoun who rather than the objective case "whom."
Geographic Clue & Rule
Rule: Test with *he* and *him*. If you can replace it with "he" (e.g., *he designs*), use *who*. If you would say "him," use *whom*.
Log your correct answers. Let's check Day 13, Question 2.
DAY 13 • Q2 Austin Demographics
"Lured by the vibrant music scene and the thriving economy. Thousands of young professionals move to Austin each month."
What is the correct way to rewrite this fragment and complete sentence?
A Lured by the vibrant music scene and the thriving economy, thousands of young professionals...
B Lured by the vibrant music scene and the thriving economy; thousands of young professionals...
C Lured by the vibrant music scene and the thriving economy thousands of young professionals...
D Make no change
Skill: Correcting Sentence Fragments Next slide reveals key
DAY 13 • Q2 KEY Verified Answer
A
Combine fragment using a comma separator
"Lured by... economy, thousands of young..."
Explanation
The first group of words is a dependent participial phrase that lacks a subject and a conjugated verb, making it a sentence fragment. Option A corrects this by attaching the fragment to the main clause using a comma.
Geographic Clue & Rule
Rule: Do not let descriptive phrases stand alone with a period. Attach them with a comma to the independent sentence they describe.
Log your correct answers. Let's move to Day 14!
DAY 14 • Q1 Severe Weather & Northerns
"A sudden temperature drop—known as a Blue Northern, can plunge parts of Texas from shirt-sleeve weather into freezing conditions."
What change should be made to correct the punctuation in this sentence?
A Change the comma after Northern to an em dash (—)
B Change the dash after drop to a comma
C Delete the dash after drop
D Make no change
Skill: Unifying Punctuation for Parenthetical Interruptions Next slide reveals key
DAY 14 • Q1 KEY Verified Answer
A
Pair the em dashes correctly
"...drop**—known as a Blue Northern—**can plunge..."
Explanation
The sentence contains a parenthetical interrupter ("known as a Blue Northern"). When setting off non-essential elements using dashes, you must use them as a matching pair (one to open, one to close). Mixing a dash with a comma is incorrect.
Geographic Clue & Rule
Rule: Dashes are like brackets or parentheses. If you open an interruption with an em dash (—), you must close it with an em dash (—) before resuming the main sentence.
Log your correct answers. Let's check Day 14, Question 2.
DAY 14 • Q2 Tornado Alleys
"Because the flat plains offer no barriers to block cold arctic air, residents don't have no protection against sudden temperature drops."
What change should be made to correct this sentence?
A change don't have no to don't have any
B change don't have no to haven't got no
C change don't have no to don't got no
D Make no change
Skill: Eliminating Double Negatives Next slide reveals key
DAY 14 • Q2 KEY Verified Answer
A
Change "no" to "any" to fix the double negative
"...residents don't have any protection..."
Explanation
The sentence contains a double negative: "don't" (contraction for do not) and "no." Using two negatives in the same clause is non-standard because they cancel each other out. Option A corrects this by changing "no" to "any."
Geographic Clue & Rule
Rule: Avoid double negative structures. Pair negative contraction verbs with positive adjectives like *any* or *some* rather than negative terms like *no*, *none*, or *nothing*.

DAY 15 • Q1 Houston Space Economy
"The Johnson Space Center, which was built and constructed in the city of Houston, is responsible for training astronauts who fly into space."
What is the most concise and effective way to revise this sentence to remove wordiness?
A Located in Houston, the Johnson Space Center trains astronauts for space missions.
B Built and constructed in Houston, the Johnson Space Center is where astronauts are trained for space missions by trainers.
C The Johnson Space Center is in Houston, and it trains astronauts who fly into space.
D Make no change

DAY 15 • Q1 KEY Verified Answer
A
Select clean, concise revision A
"Located in Houston, the Johnson Space Center trains..."
Explanation
The original sentence is heavily cluttered. "Built and constructed" is repetitive, and "city of Houston" and "astronauts who fly into space" are unnecessarily wordy. Option A says everything in a single, crisp, clear clause of just eleven words.
Geographic Clue & Rule
Rule: Wordiness is a massive EOC target. When choosing the best revision, the shortest answer that retains the correct original meaning and grammar is almost always correct.

DAY 15 • Q2 NASA Global Alliances
"NASA continues to expand it's international collaborations to prepare for human missions to Mars."
What change, if any, should be made to the underlined word?
A change it's to its
B change it's to its'
C change it's to itses
D Make no change
Skill: Possessive Pronoun Homophones (Its vs. It's) Next slide reveals key
DAY 15 • Q2 KEY Verified Answer
A
Change contraction "it's" to possessive "its"
"NASA continues to expand its international collaborations..."
Explanation
The sentence requires a singular neuter possessive pronoun to show that the collaborations belong to NASA. The word it's is a contraction meaning "it is" or "it has." The correct possessive pronoun is its, which has no apostrophe.
Geographic Clue & Rule
Rule: Possessive pronouns (*its, hers, his, ours, yours, theirs*) never contain apostrophes. If you can't substitute "it is" in the sentence, use *its*.
Congratulations! You have completed the 15-Day GeoGrammar EOC curriculum!
