All questions
Question 1
Select the most precise replacement for the underlined words.
"The scientist kept looking at the data many times before drawing a conclusion."
- again and again
- over and over again repeatedly
- on multiple occasions afterward
- numerous times (correct answer)
Explanation: When you encounter questions about word precision, you're being tested on your ability to choose the most concise and effective expression while maintaining the original meaning.
The phrase "many times" needs a replacement that conveys repeated examination of data without unnecessary wordiness or redundancy. Option D, "numerous times," accomplishes this perfectly. It maintains the exact meaning while using more sophisticated vocabulary that's appropriate for scientific writing. "Numerous" is more precise than "many" and creates a cleaner, more professional tone.
Let's examine why the other options fall short. Option A, "again and again," is overly casual and repetitive for scientific writing. While it conveys repetition, it lacks the precision expected in formal contexts. Option B, "over and over again repeatedly," contains obvious redundancy—"over and over again" and "repeatedly" mean the same thing, making this choice wordy and awkward. Option C, "on multiple occasions afterward," changes the original meaning by adding "afterward," which suggests the looking happened only after something else occurred, rather than throughout the process.
Remember that precision in writing means choosing words that are exact, concise, and appropriate for the context. Avoid redundant phrases and overly casual language in formal writing. When replacing words or phrases, ensure your choice maintains the original meaning while improving clarity and sophistication. The best replacements are often shorter and use more precise vocabulary rather than multiple words that say the same thing.
Question 2
Cameras flashed as the astronaut stepped onto the stage. The crowd cheered wildly, eager to hear about the mission to Mars. Maria, a budding engineer, listened closely, hoping to learn more about space exploration.
Which sentence added after the passage would improve its clarity by explicitly connecting Maria's interest to the event?
- Maria had arrived early to get a good seat near the front row.
- Maria had followed every detail of the mission and dreamed of designing spacecraft herself one day. (correct answer)
- The auditorium was filled to capacity, and security guards stood at each exit.
- Mars, the fourth planet from the sun, has long intrigued scientists and writers alike.
Explanation: This question tests your ability to identify sentences that create clear connections between different elements in a passage. When you see a question asking about "improving clarity by connecting" ideas, look for the answer choice that explicitly links the concepts mentioned.
The passage introduces Maria as "a budding engineer" who "listened closely, hoping to learn more about space exploration," but it doesn't clearly explain why this particular astronaut's presentation would be especially meaningful to her. Answer choice B bridges this gap perfectly by stating "Maria had followed every detail of the mission and dreamed of designing spacecraft herself one day." This sentence explicitly connects her engineering aspirations to the specific Mars mission being discussed, showing why she's so invested in this particular event.
Let's examine why the other choices don't work. Choice A mentions Maria arriving early for a good seat, but this doesn't explain the connection between her engineering interests and the Mars mission—it's just about her physical placement. Choice C describes the crowded auditorium and security, which shifts focus away from Maria entirely and doesn't clarify her personal connection to the event. Choice D provides general information about Mars, but again fails to link Maria's specific engineering dreams to this astronaut's mission.
When tackling clarity questions on the TACHS, always ask yourself: "What gap in understanding does this passage have, and which answer choice fills that specific gap?" Look for choices that create logical bridges between ideas rather than simply adding more details.
Question 3
The town council considered three proposals for the vacant lot downtown: a parking garage, a community garden, and a small shopping center. After lengthy debate, members voted in favor of the community garden.
Which transition sentence would best begin the next paragraph to clearly signal the result of the council's decision?
- Historically, the town has valued green spaces over commercial ventures.
- Meanwhile, various other issues were still on the council's crowded agenda.
- As a consequence of the vote, plans for the garden moved forward immediately. (correct answer)
- In contrast, some residents argued earlier for more parking downtown.
Explanation: Transition sentences serve as bridges between paragraphs, guiding readers smoothly from one idea to the next. When you encounter questions about transitions, focus on the logical relationship between what came before and what should follow.
The passage establishes a clear cause-and-effect sequence: the council debated three options and voted for the community garden. The next paragraph should logically show what happened as a result of that decision. Choice C provides exactly this connection with "As a consequence of the vote, plans for the garden moved forward immediately." This transition clearly signals that we're moving from the decision itself to its immediate effects.
Choice A shifts focus to historical context about the town's preferences, which doesn't follow logically from the specific vote just described. Choice B uses "Meanwhile" to introduce unrelated council business, completely abandoning the garden topic when the reader expects to learn about the vote's impact. Choice D looks backward with "In contrast" to revisit earlier arguments about parking, rather than moving forward to show what the garden vote accomplished.
Notice how wrong transitions either jump to unrelated topics (A and B) or move in the wrong direction chronologically (D). The correct transition maintains focus on the main topic while advancing the narrative logically forward.
When tackling transition questions, always ask yourself: "What logical relationship should connect these paragraphs?" Look for transitions that maintain topic focus while clearly signaling the appropriate relationship—whether it's cause-and-effect, contrast, sequence, or elaboration.
Question 4
During the field trip, students visited the historical museum, toured the capitol building, and ate lunch at a local park.
Which concluding sentence best maintains the paragraph's clarity and parallel structure?
- At the end of the day, a trip back to school happened so students could share moments that were favorites.
- The day ended with a return to school, sharing favorite moments being what everyone did.
- They ended the day by returning to school, where everyone shared favorite moments. (correct answer)
- Concluding the day, the bus drove back to school and favorite moments were shared by students.
Explanation: When you encounter questions about parallel structure and clarity, you're being tested on your ability to maintain consistent grammatical patterns and clear, direct expression. This passage describes three activities using a parallel structure: "visited," "toured," and "ate" - all past tense verbs in active voice.
Choice C maintains this clarity and parallel structure perfectly. "They ended the day by returning to school, where everyone shared favorite moments" uses clear, active language with a logical flow. The sentence structure mirrors the passage's direct, straightforward style, and the pronoun "they" clearly refers to the students.
Choice A fails because it uses awkward passive construction ("a trip back to school happened") and places the object awkwardly at the end ("moments that were favorites" instead of "favorite moments"). Choice B creates confusion with a dangling modifier - "sharing favorite moments being what everyone did" is unnecessarily wordy and unclear about who performed the action. Choice D shifts between active and passive voice inconsistently ("the bus drove" is active, but "favorite moments were shared by students" is passive), breaking the paragraph's established pattern.
For TACHS written expression questions, always look for the answer that maintains the same grammatical patterns established in the passage. When you see parallel structure in the original text (like the three verbs here), choose the option that continues that pattern with clear, direct language rather than passive or overly complex constructions.
Question 5
The art teacher explained the project carefully. Some students, however, still seemed confused about the required materials.
Which sentence added next would clarify the teacher's response to the confusion?
- Art projects often require many different tools for completion.
- A few minutes later, the bell rang, ending the period.
- The required materials included paintbrushes, paper, and palettes.
- She provided a detailed checklist of supplies and posted it on the classroom wall. (correct answer)
Explanation: This question tests your ability to identify which sentence would best address a specific problem mentioned in the passage. When you see questions asking what sentence would "clarify" or "respond to" something, look for the option that directly solves the stated issue.
The passage tells us that students were confused about the required materials despite the teacher's careful explanation. The next sentence should logically show how the teacher addressed this specific confusion about materials.
Option D is correct because it shows the teacher taking concrete action to resolve the confusion: "She provided a detailed checklist of supplies and posted it on the classroom wall." This directly responds to the students' confusion by giving them a clear, visible reference for the required materials.
Option A is wrong because it makes a general statement about art projects but doesn't show the teacher doing anything to help the confused students. Option B is incorrect because the bell ringing is unrelated to addressing the confusion—it actually suggests the problem went unresolved. Option C lists some materials but doesn't indicate that the teacher provided this information to help the students, so it doesn't show her response to their confusion.
When you encounter "what happens next" questions on the TACHS, always look for the option that logically follows from the situation described and addresses any problems mentioned. The correct answer should feel like a natural continuation that resolves tensions or issues raised in the passage.
Question 6
Scientists often rely on precise measurements. Even a small error can lead to incorrect conclusions.
Which connecting word would best replace the period between the two sentences to emphasize the relationship?
- However,
- Therefore, (correct answer)
- Otherwise,
- Meanwhile,
Explanation: This question tests your understanding of logical connectors and how they signal relationships between ideas. When you encounter questions about connecting sentences, focus on the cause-and-effect or logical flow between the two statements.
Let's analyze the relationship: The first sentence establishes that scientists need precise measurements, and the second sentence explains what happens when measurements aren't precise - incorrect conclusions result. This creates a cause-and-effect relationship where the second sentence provides the logical consequence of the first.
Choice B) "Therefore," is correct because it signals this cause-and-effect relationship. It shows that incorrect conclusions are the direct result of imprecise measurements, emphasizing why precision is so crucial in scientific work.
Choice A) "However," is wrong because it indicates contrast or opposition. These sentences don't contradict each other - they actually support the same point about the importance of precision.
Choice C) "Otherwise," suggests an alternative scenario or what would happen if conditions weren't met. While this might seem plausible, it doesn't capture the direct causal relationship as effectively as "therefore."
Choice D) "Meanwhile," indicates something happening at the same time, which doesn't fit the logical flow. The sentences aren't describing simultaneous events but rather a cause and its consequence.
Strategy tip: When choosing connecting words, identify whether sentences show cause-and-effect (therefore, consequently), contrast (however, nevertheless), alternatives (otherwise), or time relationships (meanwhile, subsequently). The TACHS frequently tests these logical relationships, so practice recognizing the underlying connection between ideas before selecting your connector.
Question 7
Choose the sentence that presents the idea most clearly.
- Carla postponed the meeting because the required documents, which she forgot at home, were missing.
- Carla postponed the meeting because she forgot the required documents at home. (correct answer)
- Carla postponed the meeting, at home the required documents were forgotten by her.
- Because the required documents were missing, they were forgotten at home by Carla, so the meeting was postponed.
Explanation: When you encounter clarity questions on the TACHS, you're being tested on your ability to identify the most direct and efficient way to express an idea. Clear writing eliminates unnecessary words and avoids confusing sentence structures.
Choice B presents the idea most effectively because it follows a simple, logical structure: subject + action + reason. "Carla postponed the meeting because she forgot the required documents at home." This sentence is direct, concise, and immediately clear about the cause-and-effect relationship.
Choice A is unnecessarily wordy and awkward. The phrase "which she forgot at home, were missing" creates a confusing double explanation – the documents were missing because she forgot them, but this version makes it sound like two separate problems. The relative clause "which she forgot at home" interrupts the flow and makes the sentence harder to follow.
Choice C has serious structural problems. The comma splice creates two incomplete thoughts awkwardly joined together. "At home the required documents were forgotten by her" uses passive voice unnecessarily and creates an unnatural word order that confuses the meaning.
Choice D is the worst option, containing redundant information and illogical sequencing. It says the documents "were missing" and "were forgotten" as if these are separate issues, then adds "so the meeting was postponed" unnecessarily. The sentence is wordy and confusing.
For TACHS clarity questions, always choose the version that expresses the complete thought in the fewest words while maintaining proper grammar. Avoid passive voice, redundancy, and unnecessary clauses that interrupt the main idea.
Question 8
Which option best clarifies the meaning of this sentence?
"While reading the novel, the plot twist upset Jamal."
- While reading, the plot twist of the novel upset Jamal.
- Reading the novel, the plot twist was upsetting to Jamal.
- The plot twist upset Jamal while reading the novel.
- While reading the novel, Jamal was upset by the plot twist. (correct answer)
Explanation: This question tests your ability to recognize and fix dangling modifiers, which occur when the introductory phrase doesn't clearly connect to the right subject in the sentence.
The original sentence "While reading the novel, the plot twist upset Jamal" contains a dangling modifier. The phrase "While reading the novel" should logically modify whoever is doing the reading (Jamal), but grammatically it appears to modify "the plot twist" - suggesting the plot twist itself was reading the novel, which is nonsensical.
Option D correctly fixes this error by making Jamal the clear subject immediately after the modifying phrase: "While reading the novel, Jamal was upset by the plot twist." Now the sentence logically indicates that Jamal was reading and Jamal was upset.
Option A still has the dangling modifier problem - "While reading" doesn't clearly connect to Jamal as the reader. Option B creates the same issue with "Reading the novel" appearing to modify "the plot twist" rather than Jamal. Option C avoids the dangling modifier but creates awkward phrasing that's less clear than option D, and the timing relationship between the reading and the upset feeling isn't as precisely expressed.
When you encounter sentences with introductory phrases (especially those starting with "while," "after," "before," or "-ing" words), always check that the phrase logically modifies the subject that immediately follows it. The person or thing doing the action in the introductory phrase should be the same as the subject of the main clause.
Question 9
Which revision most clearly expresses the comparison?
"Our soccer team practiced harder than any school in the district."
- Our soccer team practiced with more effort than any district school.
- Our soccer team practiced harder than any school team in the district had practiced.
- Our soccer team practiced harder than any other school's team in the district. (correct answer)
- In the district, our soccer team practiced harder than all schools.
Explanation: When you encounter comparison questions, you need to ensure that you're comparing like things to like things. The original sentence has a logical error: it compares "our soccer team" (people) to "any school" (buildings/institutions), which creates an illogical comparison.
The correct answer is C because it fixes this comparison error by comparing "our soccer team" to "any other school's team" - now you're comparing teams to teams, which makes logical sense. The word "other" is crucial here because it excludes your own team from the group you're comparing against. Without "other," the sentence would illogically suggest your team practiced harder than itself.
Let's examine why the other options fail: A) still compares your "team" to "district school" (institution), maintaining the logical error. B) is grammatically awkward and unnecessarily wordy with "had practiced," and while it attempts to compare teams, the phrasing is clunky. D) returns to the original error by comparing your "team" to "all schools" (institutions).
Notice that comparison errors often involve mismatched categories - people vs. institutions, things vs. qualities, etc. The test writers frequently create these traps because they sound almost right at first glance.
Strategy tip: When you see comparison questions, immediately identify what's being compared to what. Draw a mental line: "X compared to Y." Then check that X and Y are the same type of thing. If they're not, look for the answer choice that makes them match while maintaining the intended meaning.
Question 10
Choose the option that improves clarity by eliminating a dangling modifier.
"After finishing the experiment, the report was written and submitted."
- Having finished, the report after the experiment was written and submitted.
- The report was written and submitted, after finishing the experiment.
- After finishing the experiment, writing and submitting the report was completed.
- After finishing the experiment, we wrote and submitted the report. (correct answer)
Explanation: When you encounter questions about dangling modifiers, you need to identify who or what is performing the action described in the introductory phrase. A dangling modifier occurs when the subject performing the action isn't clearly stated or is misplaced.
In the original sentence "After finishing the experiment, the report was written and submitted," the phrase "after finishing the experiment" suggests that someone finished the experiment, but the sentence makes it sound like the report itself finished the experiment. Reports can't finish experiments—people do.
Option D correctly fixes this by providing a clear subject: "After finishing the experiment, we wrote and submitted the report." Now it's clear that "we" (the people) finished the experiment and then wrote the report.
Option A rearranges the words awkwardly but still fails to identify who finished the experiment. The phrase "Having finished" still dangles without a proper subject. Option B simply moves the modifier to the end but doesn't solve the fundamental problem—we still don't know who finished the experiment. Option C attempts to fix the issue but creates new problems by making "writing and submitting the report" the subject that apparently finished the experiment, which doesn't make logical sense.
To spot dangling modifiers, always ask: "Who is doing the action in the introductory phrase?" If that person or thing isn't the subject of the main clause, you've found a dangling modifier that needs fixing by adding the appropriate subject.
Question 11
Which version most effectively combines the ideas without losing clarity?
"Hannah likes painting. She also enjoys photography."
- Hannah likes painting and enjoys photography as well.
- Hannah, enjoying photography, likes painting.
- Hannah enjoys photography and likes painting too.
- Hannah likes painting in addition to enjoying photography. (correct answer)
Explanation: When combining sentences, you want to create a smooth, natural flow while preserving the equal importance of both ideas. The key is choosing connecting words that clearly show the relationship between the concepts without making one idea seem secondary.
Option D is most effective because "in addition to" explicitly signals that both activities—painting and photography—are equally important hobbies. This phrase creates a balanced structure that maintains the original meaning while combining the sentences elegantly. The construction flows naturally and leaves no ambiguity about Hannah's interests.
Let's examine why the other options fall short. Choice A uses "and...as well," which creates redundancy—both words serve the same function, making the sentence wordy and less polished. Choice B restructures the sentence with "enjoying photography" as a participial phrase, which subordinates photography to painting, suggesting painting is her primary interest. This changes the meaning from the original equal relationship. Choice C uses "and...too," which, like option A, is redundant and less sophisticated than necessary.
The best sentence combinations use precise connecting words that match the intended relationship between ideas. When combining sentences about equal concepts, look for connectors like "in addition to," "as well as," or simple "and"—but avoid doubling up on these connecting elements, which creates wordiness and reduces clarity.
Question 12
Which sentence conveys the meaning most precisely?
"The dog was kind of sick after eating the leftovers."
- The dog was a little bit sick after eating leftovers.
- After eating the leftovers, the dog felt ill. (correct answer)
- The dog became some sort of sick from the leftovers it ate.
- Having eaten the leftovers, sickness was felt by the dog.
Explanation: When tackling precision in writing, you're looking for the sentence that eliminates vague language and conveys the meaning most clearly and directly.
The correct answer is B because it replaces the imprecise phrase "kind of sick" with the specific word "ill." This version is clean, direct, and uses precise vocabulary. The sentence structure is also clear and active, making the cause-and-effect relationship between eating leftovers and becoming sick immediately apparent.
Let's examine why the other options fall short: Choice A simply substitutes one vague expression ("kind of") with another equally imprecise phrase ("a little bit"), so it doesn't improve precision at all. Choice C introduces unnecessary wordiness with "some sort of sick," which is even more awkward and imprecise than the original. Additionally, the phrase "from the leftovers it ate" creates redundancy since we already know the dog ate the leftovers. Choice D uses passive voice ("sickness was felt"), which makes the sentence unnecessarily wordy and less direct than the active voice alternative.
When you encounter questions about precise writing on the TACHS, focus on eliminating vague qualifiers like "kind of," "sort of," and "a little bit." These phrases weaken your writing and make it less precise. Look for the option that uses specific vocabulary, active voice when possible, and eliminates unnecessary words while maintaining the original meaning.
Question 13
Choose the most concise and clear revision.
"There are many students who believe that shorter lunch periods would not be a good idea."
- Many students have a belief that shorter lunch periods are not a good idea.
- A lot of the students have the belief that shorter lunch periods would not be a good idea.
- Many students believe that shorter lunch periods would not be a good idea. (correct answer)
- There are many students believing that shorter lunch periods are not a good idea.
Explanation: This question tests your ability to identify concise, clear writing by eliminating unnecessary words and awkward constructions. When revising sentences, you should always look for ways to remove redundancy while maintaining the original meaning.
The correct answer is C because it eliminates the wordy "There are..." construction from the original sentence. By starting directly with "Many students believe," the sentence becomes more direct and active. This revision removes unnecessary words without changing the meaning or clarity.
Let's examine why the other options are problematic. Option A replaces the simple verb "believe" with the wordy phrase "have a belief that," which adds unnecessary words without improving clarity. Option B compounds this problem by using both "A lot of the students" (wordier than "Many students") and "have the belief that" (wordier than "believe"). Option D creates an awkward construction with "students believing" instead of "students believe," making the sentence grammatically weaker and less natural.
Notice that all incorrect options either add unnecessary words or create awkward phrasing. Option A uses five words ("have a belief that") where one word ("believe") would suffice. Option B is the wordiest of all choices. Option D changes the verb form in a way that makes the sentence sound incomplete.
When tackling conciseness questions on the TACHS, remember this strategy: choose the option that expresses the same idea with the fewest words while maintaining proper grammar and clarity. Always prefer simple, direct constructions over wordy phrases.
Question 14
Identify the option that removes wordiness without sacrificing meaning.
"In spite of the fact that the forecast predicted rain, we decided to go hiking anyway."
- We decided to go hiking anyway, even though the forecast predicted rain.
- Despite the forecast that predicted rain, we decided anyway to go hiking.
- The forecast predicted rain; nevertheless, we decided to go hiking anyway.
- Although the forecast predicted rain, we decided to go hiking anyway. (correct answer)
Explanation: When you encounter questions about removing wordiness, focus on eliminating unnecessary words while preserving the original meaning and maintaining natural sentence flow.
The original sentence contains the wordy phrase "in spite of the fact that," which can be streamlined using more concise alternatives. Let's examine how each option handles this reduction.
Option D successfully replaces the wordy opening with "Although," which conveys the same contrasting meaning in just one word. The sentence flows naturally and eliminates unnecessary words without changing the meaning or creating awkward phrasing.
Option A reduces some wordiness but creates redundancy by using both "anyway" and "even though," which express similar ideas. The double emphasis on contrast makes the sentence less efficient than it could be.
Option B attempts to condense the opening but creates an awkward construction with "Despite the forecast that predicted rain." The word placement also feels unnatural with "decided anyway to go hiking" instead of the more flowing "decided to go hiking anyway."
Option C replaces the wordy opening but introduces a semicolon and "nevertheless," which actually adds formality and length rather than reducing it. While grammatically correct, it doesn't achieve the goal of removing wordiness.
Remember that effective revision eliminates redundant phrases and unnecessary words while maintaining clarity and natural flow. Look for opportunities to replace wordy constructions like "in spite of the fact that" with single, precise words like "although," "though," or "despite."
Question 15
Choose the revision that improves clarity by fixing the unnecessary shift in voice.
"The volunteers sorted the donations, and then the items were loaded onto the truck by the driver."
- After the volunteers sorted the donations, onto the truck the items were loaded by the driver.
- The donations were sorted by the volunteers, and then the driver loaded the items onto the truck.
- Sorting the donations, the volunteers then had the items loaded onto the truck by the driver.
- The volunteers sorted the donations, and then the driver loaded the items onto the truck. (correct answer)
Explanation: When you encounter questions about voice shifts, you're looking for consistency between active and passive voice within a sentence or paragraph. Voice shifts occur when writers unnecessarily switch between having the subject perform the action (active voice) and having the action performed on the subject (passive voice).
The original sentence demonstrates this problem: "The volunteers sorted the donations" uses active voice (volunteers perform the action), while "the items were loaded onto the truck by the driver" uses passive voice (items receive the action). This shift creates awkward, unclear writing.
Choice D fixes this by maintaining active voice throughout: "The volunteers sorted the donations, and then the driver loaded the items onto the truck." Both clauses now have clear subjects performing clear actions, making the sentence flow naturally and improving readability.
Choice A simply rearranges words while keeping the problematic passive construction "were loaded by the driver." The awkward word order "onto the truck the items were loaded" actually makes clarity worse.
Choice B creates the opposite problem by shifting from passive to active voice: "were sorted by" (passive) followed by "driver loaded" (active). While this eliminates one passive construction, it still contains an unnecessary voice shift.
Choice C uses a participial phrase "Sorting the donations" but maintains the passive voice "had the items loaded...by the driver," failing to address the core issue while adding unnecessary complexity.
Remember: consistency in voice creates clearer, more direct writing. When you spot voice shifts, look for the answer choice that uses active voice throughout both clauses.
Question 16
Which sentence best removes an unnecessary intensifier while maintaining emphasis?
"The presentation was extremely informative and interesting."
- The presentation was highly informative and interesting.
- The presentation was informative and interesting. (correct answer)
- The presentation was very informative and interesting indeed.
- The presentation was so informative and interesting.
Explanation: When you encounter questions about removing unnecessary intensifiers, you're being tested on concise writing that maintains impact without relying on weak modifiers.
The goal here is to eliminate redundant emphasis while preserving the sentence's meaning. The original sentence uses "extremely," which is an intensifier that doesn't add meaningful information. Strong adjectives like "informative" and "interesting" already convey positive qualities effectively on their own.
Option B correctly removes "extremely" while keeping the sentence clean and direct. The adjectives "informative" and "interesting" carry sufficient weight without additional modification, creating a more confident and precise statement.
Option A simply replaces one weak intensifier ("extremely") with another ("highly"). This doesn't solve the underlying problem of unnecessary modification and still creates wordy, less impactful writing.
Option C makes the problem worse by adding both "very" and "indeed." This doubles down on unnecessary intensifiers, creating an even more cluttered sentence that weakens rather than strengthens the emphasis.
Option D creates an incomplete construction with "so informative and interesting." The word "so" sets up an expectation for a result or comparison ("so interesting that..."), but the sentence doesn't deliver on this promise, leaving it grammatically incomplete.
Remember this pattern: strong adjectives and verbs rarely need intensifiers. When you see words like "extremely," "very," "highly," or "really," ask yourself if removing them would make the writing more direct and powerful. Often, less is more in effective writing.
Question 17
Select the clearest revision.
"To prepare for exams, notes should be reviewed regularly."
- In preparation for exams, regular review of notes should happen.
- Notes, to prepare for exams, should be reviewed regularly.
- Regular review of notes is what should be done in preparation for exams.
- To prepare for exams, students should review their notes regularly. (correct answer)
Explanation: This question tests your ability to identify and fix dangling modifiers, a common error in written expression. When a sentence begins with a modifying phrase like "To prepare for exams," that phrase must logically connect to the subject that immediately follows it.
The correct answer is D because it provides a clear subject ("students") that can logically perform the action described in the opening phrase. Students are the ones who prepare for exams, so the sentence structure makes perfect sense: "To prepare for exams, students should review their notes regularly."
Choice A creates awkward, wordy phrasing with "regular review of notes should happen," which doesn't clearly identify who is doing the preparing or reviewing. Choice B places the modifying phrase "to prepare for exams" in an awkward middle position that disrupts the sentence flow and creates confusion about what is being modified. Choice C uses unnecessarily wordy construction with "is what should be done," making the sentence verbose and unclear while still failing to identify who should be doing the preparing.
The original sentence contains a dangling modifier because "notes" cannot logically "prepare for exams" – only people can prepare for exams. This creates confusion about who is performing the action.
When you encounter revision questions, always check that modifying phrases at the beginning of sentences logically connect to the subject that follows. Ask yourself: "Who or what is actually performing the action described in the opening phrase?" The subject must be someone or something capable of that action.
Question 18
Identify the revision that improves clarity by avoiding a vague pronoun reference.
"Mia told Ana that she would need more practice before the concert."
- Before the concert, Mia told Ana that she would need more practice.
- Mia told Ana that Ana would need more practice before the concert. (correct answer)
- Mia told Ana that Mia would need more practice before the concert.
- Mia told Ana before the concert that she would need to practice more.
Explanation: Pronoun reference questions test whether you can identify and fix unclear pronouns that could refer to multiple people or things. When you encounter a sentence with confusing pronouns, look for words like "he," "she," "it," or "they" that don't clearly point to one specific noun.
In the original sentence, "she" creates ambiguity because it could refer to either Mia or Ana. When you have two people of the same gender in a sentence, pronouns become problematic. The revision needs to eliminate this confusion by clearly specifying who needs the practice.
Choice B correctly replaces the vague pronoun "she" with the specific name "Ana," making it crystal clear that Ana is the one who needs more practice. This removes all ambiguity while maintaining the sentence's original meaning and flow.
Choice A simply rearranges the sentence structure but keeps the problematic pronoun "she," so the ambiguity remains. Choice C replaces "she" with "Mia," which changes the meaning entirely—now Mia needs practice instead of Ana, which may not reflect the intended meaning. Choice D rearranges words and changes "practice" to "practice more" but still contains the unclear pronoun "she."
When you see pronoun reference questions on the TACHS, immediately scan for pronouns that could point to multiple nouns. The correct answer will typically replace the vague pronoun with a specific noun, even if it sounds slightly repetitive. Clear communication trumps elegant variation when avoiding confusion.
Question 19
Select the revision that removes ambiguity.
"The coach praised Jordan more than Alex."
- Praising Jordan more, Alex was not praised by the coach.
- The coach praised Jordan more than Alex did.
- The coach, more than Alex, praised Jordan.
- The coach praised Jordan more than he praised Alex. (correct answer)
Explanation: When you encounter sentences with comparative structures like "more than," watch for ambiguity about what exactly is being compared. The original sentence "The coach praised Jordan more than Alex" creates confusion because it could mean either that the coach praised Jordan more than the coach praised Alex, OR that the coach praised Jordan more than Alex praised Jordan.
Answer choice D removes this ambiguity by making the comparison explicit: "The coach praised Jordan more than he praised Alex." The pronoun "he" clearly refers back to "the coach," and the repeated verb "praised" makes it unmistakable that we're comparing how much the coach praised Jordan versus how much the coach praised Alex.
Let's examine why the other options fail. Choice A completely changes the sentence structure and creates a passive construction that doesn't preserve the original meaning or clearly resolve the ambiguity. Choice B actually maintains one interpretation of the original ambiguity—it suggests Alex did some praising, but it's still unclear what Alex did compared to the coach's actions. Choice C rearranges the sentence to suggest that between the coach and Alex, the coach was the one doing more praising of Jordan, but this changes the intended meaning and creates new confusion about what Alex's role was.
For comparative structures on the TACHS, always check whether the comparison could be interpreted multiple ways. The clearest revision will explicitly state both parts of the comparison, often by repeating key words like the subject and verb.
Question 20
Which revision of the sentence improves clarity?
"Rushing down the hallway, the bell was ringing when Nadia reached her locker."
- The bell was ringing, and rushing down the hallway was Nadia when she reached her locker.
- Rushing down the hallway, Nadia reached her locker just as the bell rang. (correct answer)
- Rushing down the hallway, the bell rang just as Nadia got to her locker.
- When Nadia was rushing down the hallway the bell rang upon reaching her locker.
Explanation: When you encounter a sentence that starts with a descriptive phrase like "Rushing down the hallway," you need to check what comes immediately after the comma. That opening phrase must logically describe whoever or whatever follows the comma—this is called a dangling modifier when it doesn't match up correctly.
In the original sentence, "Rushing down the hallway" is followed by "the bell," which creates confusion because bells don't rush down hallways. Choice B fixes this error by placing "Nadia" right after the comma, making it clear that she is the one rushing down the hallway. The sentence now flows logically: Nadia was rushing, and she reached her locker as the bell rang.
Choice A rearranges the sentence awkwardly without fixing the core problem, creating confusing word order that's hard to follow. Choice C keeps the same dangling modifier error as the original—it still suggests the bell is rushing down the hallway. Choice D creates a different problem by placing "upon reaching her locker" right after "the bell rang," which incorrectly suggests the bell reached the locker rather than Nadia.
Watch for opening phrases that describe actions or states—they must connect to the subject that immediately follows the comma. If you see phrases like "Running quickly," "Excited about the game," or "After studying all night," make sure the person or thing doing that action comes right after the comma. This is a common error pattern on writing tests.
