All questions

Question 1

Select the best replacement for the bold words.

The documentary, despite receiving praise, wasn't interesting to nobody in the class.

  1. wasn't interesting to anybody (correct answer)
  2. was interesting to nobody
  3. did not interest no one
  4. didn't have interest from none
Explanation: This question tests your ability to identify and correct double negatives, which create unintended meaning in formal writing. When you see multiple negative words in a sentence, check whether they're working together properly or canceling each other out. The original phrase "wasn't interesting to nobody" contains two negatives: "wasn't" (was not) and "nobody." In standard English, these two negatives cancel each other out, actually creating a positive meaning - suggesting the documentary WAS interesting to somebody. This contradicts the intended meaning that no one in the class found it interesting. Choice A correctly fixes this by changing "nobody" to "anybody," creating the single negative "wasn't interesting to anybody." This clearly conveys that no one in the class found the documentary interesting. Choice B keeps "nobody" but removes the other negative by changing "wasn't" to "was," creating "was interesting to nobody." While this eliminates the double negative, it creates awkward phrasing that sounds unnatural. Choice C maintains the double negative problem with "did not interest no one" - again, the two negatives (not + no one) cancel each other out mathematically. Choice D introduces even more negative elements with "didn't" and "none," while also creating the awkward phrase "have interest from," which is unnecessarily wordy and unclear. Study tip: When you spot words like "not," "no," "never," "nothing," or "nobody" appearing together, count the negatives. In formal writing, use only one negative to express a negative idea. Multiple negatives either cancel out or sound informal.

Question 2

Select the best replacement for the bold words.

The author argues that public parks should receive more funding; this is a subject which most citizens support.

  1. a position that (correct answer)
  2. this being a subject that
  3. a thing which
  4. this here is a stance which
Explanation: This question tests your ability to identify clear, concise pronoun references and eliminate wordy, awkward constructions. When you see underlined phrases with pronouns like "this," ask yourself whether the reference is clear and whether the phrasing is as direct as possible. The correct answer is A) "a position that" because it creates a clear, direct sentence: "The author argues that public parks should receive more funding; a position that most citizens support." This construction clearly identifies what the author presents (a position) and connects it smoothly to the supporting clause. The word "position" specifically and accurately describes what the author is doing when making an argument. Choice B) "this being a subject that" creates an awkward, wordy construction with unnecessary words. The phrase "this being" is clunky and less direct than needed. Choice C) "a thing which" is vague and imprecise—"thing" doesn't specifically describe what the author is presenting, and good writing avoids such generic terms when more precise options exist. Choice D) "this here is a stance which" contains redundant words ("this here") and creates an unnecessarily long, awkward phrase. When tackling pronoun reference questions on the TACHS, look for the most precise, concise replacement that clearly identifies what the pronoun refers to. Avoid constructions with "this being," "this here," or vague words like "thing." Instead, choose specific nouns like "position," "argument," or "stance" that accurately describe the concept being referenced.

Question 3

Choose the best phrase: A landscaper's earnings are often lower  .

  1. than a plumber's are (correct answer)
  2. than a plumber is
  3. compared to a plumber
  4. as a plumber's are
Explanation: The comparison is between the landscaper's earnings and the plumber's earnings, so you need the possessive 'plumber's' plus 'are' to stand for 'earnings are': 'than a plumber's are.' The tempting wrong version 'than a plumber is' compares earnings to the person, not to the plumber's earnings, so it doesn't make logical sense.

Question 4

Choose the most effective phrase: The reason for the delay was  .

  1. because of heavy traffic
  2. because traffic was heavy
  3. due to traffic being heavy
  4. that traffic was heavy (correct answer)
Explanation: After 'the reason was,' you need a noun clause, and 'that traffic was heavy' supplies one cleanly. The tempting 'because traffic was heavy' is redundant: 'reason' already expresses cause, so 'the reason was because' repeats it. 'Because of heavy traffic' and 'due to traffic being heavy' are also wordy or ungrammatical in this frame. Use 'that' to state the reason directly.

Question 5

Choose the best phrase: When people want a promotion,  .

  1. you should ask for advice
  2. one should ask for advice
  3. they should ask for advice (correct answer)
  4. a person should ask for advice
Explanation: The subject is plural "people," so the pronoun must also be plural: "they should ask for advice." The tempting choice is "you should ask for advice" because "you" can be generic, but it shifts the point of view away from "people" without matching the subject. "One" and "a person" are singular and do not agree with "people."

Question 6

Choose the clearest phrase:  , the soup was too salty to eat.

  1. After tasting the soup
  2. After we tasted the soup (correct answer)
  3. Having tasted the soup
  4. While tasting the soup
Explanation: The phrase needs a stated subject because the soup is the thing being judged, not the taster. "After we tasted the soup" makes clear who tasted, so the soup's being too salty follows logically. The tempting version "After tasting the soup" is wrong because without "we," it dangles and seems to say the soup tasted itself.

Question 7

Choose the best phrase: The evidence was thin;  , the jury convicted him.

  1. as a result
  2. nevertheless (correct answer)
  3. in addition
  4. for example
Explanation: The sentence sets up a contrast: thin evidence would normally lead to acquittal, yet the jury convicted. 'Nevertheless' signals that unexpected outcome. 'As a result' is the tempting trap because it suggests the thin evidence caused the conviction, but the meaning requires the opposite relation.

Question 8

Select the best replacement for the words in brackets.

The committee agreed that [each of the volunteers were] essential to the project's success.

  1. each of the volunteers was (correct answer)
  2. every volunteer were
  3. all of the volunteers was
  4. each volunteer are
Explanation: This question tests subject-verb agreement with collective expressions and indefinite pronouns. When you encounter phrases like "each of" or "every," pay close attention to what the actual subject is, as it determines whether you need a singular or plural verb. The key here is recognizing that "each" is the subject, not "volunteers." Even though "volunteers" is plural, the phrase "each of the volunteers" refers to every individual volunteer considered separately. Since "each" is singular, it requires the singular verb "was." Think of it as "each one was essential" rather than focusing on the plural noun that follows. Looking at the wrong answers: Choice B ("every volunteer were") incorrectly pairs the singular "every volunteer" with the plural verb "were." Choice C ("all of the volunteers was") makes the opposite error—"all" is plural and needs "were," not "was." Choice D ("each volunteer are") again mismatches singular "each volunteer" with plural "are." Choice A correctly uses "each of the volunteers was," maintaining proper subject-verb agreement between the singular subject "each" and singular verb "was." Remember this pattern: "each of," "every one of," and "either of" always take singular verbs, regardless of whether the noun in the prepositional phrase is plural. When you see these phrases, mentally cross out everything between the subject and verb to check agreement more easily. This is a common trap on standardized tests—they'll use plural nouns to distract you from the singular subject.

Question 9

Choose the sentence that is clearest and most concise.

  1. Because the concert had already begun, we tiptoed to our seats and sat quietly. (correct answer)
  2. Due to the fact that the concert had begun already, we quietly tiptoed to our seats.
  3. Since the concert was already beginning, we therefore tiptoed to our seats quietly.
  4. Since the concert already had begun, we were tiptoeing quietly to our seats.
Explanation: When you encounter questions asking for the "clearest and most concise" sentence, you're being tested on your ability to eliminate wordiness and awkward constructions while maintaining clarity and proper grammar. Choice A succeeds because it uses the concise subordinating conjunction "because," maintains parallel structure with "tiptoed" and "sat," and places adverbs naturally without redundancy. The sentence flows smoothly and expresses the complete thought efficiently. Choice B fails due to the wordy phrase "due to the fact that" when "because" would suffice. This unnecessarily inflated expression is exactly what conciseness questions target. Additionally, "quietly tiptoed" is slightly redundant since tiptoeing implies quiet movement. Choice C contains the redundant pairing "since...therefore." When you use a subordinating conjunction like "since," you don't need "therefore" in the main clause—it creates unnecessary emphasis and wordiness. The phrase "was already beginning" is also less precise than "had already begun." Choice D uses the past continuous "were tiptoeing," which suggests ongoing action rather than a completed action. This creates an awkward timeline and doesn't match the logical sequence of events as clearly as the simple past tense in choice A. Strategy tip: On conciseness questions, eliminate any answer with wordy phrases like "due to the fact that," "in order to," or redundant word pairs. Look for the version that expresses the idea most directly while maintaining grammatical correctness and natural word order.

Question 10

Replace the bracketed words with the most appropriate expression.

To win the grant, the proposal must be not only persuasive [but it should also show] strong evidence.

  1. but also display (correct answer)
  2. but it must also be showing
  3. and it should also demonstrate
  4. and also it has to show
Explanation: When you encounter brackets around words in a sentence, you're being tested on parallel structure—making sure that paired elements in a sentence have the same grammatical form. The sentence uses the correlative conjunction pair "not only...but also," which requires parallel structure. Look at what comes after "not only": the word "persuasive" (an adjective). For the sentence to be grammatically correct, what follows "but also" must match this structure. Choice A ("but also display") creates perfect parallelism. The sentence becomes "must be not only persuasive but also display strong evidence," where both elements after the correlative conjunctions are in the same form—"persuasive" (adjective) and "display" (verb) both modify what the proposal "must be" or "must do." Choice B ("but it must also be showing") breaks parallel structure by introducing a new subject and verb ("it must") and uses the awkward progressive form "be showing." Choice C ("and it should also demonstrate") completely abandons the "not only...but also" construction by switching to "and," which destroys the intended correlative relationship. Choice D ("and also it has to show") makes the same error as C by using "and" instead of "but also," plus adds unnecessary wordiness with "it has to." Remember this pattern: correlative conjunctions like "not only...but also," "either...or," and "neither...nor" always require parallel structure. When you see these pairs, check that the elements following each conjunction match grammatically.

Question 11

Select the version that maintains proper parallelism.

The new app allows users to store photos, edit videos, and they can share documents.

  1. share documents (correct answer)
  2. the sharing of documents
  3. for sharing documents
  4. they share documents
Explanation: When you encounter a sentence with a series of actions or items, you need to check for parallel structure—all elements in the series should follow the same grammatical pattern. In this sentence, the series begins with "allows users to store photos, edit videos, and..." The first two elements follow the pattern: "to [verb] [object]" where the "to" is understood after the first item. So you have "to store photos" and "to edit videos." For parallelism, the third element must follow this same pattern with a simple verb plus object. Choice A) "share documents" maintains perfect parallelism. It follows the established pattern of [verb] + [object], creating the complete series: "store photos, edit videos, and share documents." Choice B) "the sharing of documents" breaks parallelism by switching to a gerund phrase with an article. This doesn't match the verb-object pattern of the first two items. Choice C) "for sharing documents" disrupts the pattern by introducing a preposition and gerund, creating an entirely different grammatical structure. Choice D) "they share documents" (the original) destroys parallelism by inserting a subject and creating a complete clause instead of maintaining the simple verb-object pattern. For TACHS parallelism questions, identify the established pattern in the series first, then choose the option that exactly matches that pattern. When you see items connected by "and," "or," or commas in a series, they should all have the same grammatical structure—same verb forms, same parts of speech, same sentence construction.

Question 12

Choose the phrase that best completes the sentence.

Neither the swimmers nor their coach   satisfied with the relay time.

  1. was (correct answer)
  2. were
  3. are being
  4. have been
Explanation: When you encounter "neither...nor" constructions, you're dealing with a specific subject-verb agreement rule that trips up many students. The key principle is that with "neither...nor," the verb agrees with the subject closest to it. In this sentence, "Neither the swimmers nor their coach   satisfied," you have two subjects joined by "neither...nor": "the swimmers" (plural) and "their coach" (singular). Since "their coach" comes second and is closest to the verb, the verb must agree with this singular subject. Therefore, "was" (A) is correct because it's the singular past tense form that matches "coach." Let's examine why the other options don't work: (B) "were" is incorrect because it's plural and would agree with "swimmers," but the rule requires agreement with the closest subject, which is singular "coach." (C) "are being" fails for two reasons—it's plural (disagreeing with "coach") and uses present tense when the context suggests a completed action in the past. (D) "have been" is also wrong because "have" is plural, again disagreeing with the singular "coach." Remember this pattern: with "neither...nor" (and similarly "either...or"), always make the verb agree with whichever subject comes second, right before the verb. A helpful memory trick is "the closest subject wins." This same rule applies whether the closest subject is singular or plural, so practice identifying which subject sits right next to the verb slot.

Question 13

Choose the sentence that expresses the idea most clearly.

  1. Many students enjoy science class because the experiments are hands-on and engaging. (correct answer)
  2. Science class is enjoyed by many students due to the fact that the experiments are hands-on and they are engaging.
  3. Because the experiments are hands-on, science class is an enjoyment to many students.
  4. The enjoyment of science class by many students comes from the hands-on engaging experiments that it has.
Explanation: When you encounter clarity questions on written expression tests, focus on finding the sentence that communicates its message most directly and efficiently. Clear writing uses active voice, avoids unnecessary words, and maintains straightforward sentence structure. Choice A expresses the idea most clearly because it uses active voice ("students enjoy") and presents the information in a logical, direct sequence. The sentence flows naturally from subject to action to reason, making it easy to follow and understand. Choice B suffers from several clarity issues: it uses passive voice ("is enjoyed by"), includes the wordy phrase "due to the fact that" instead of simply "because," and creates awkward repetition with "they are engaging" that makes the pronoun reference unclear. Choice C uses unnecessarily formal and awkward phrasing with "is an enjoyment to many students." This construction sounds unnatural and forces the reader to work harder to understand the meaning. Choice D creates a convoluted sentence structure by turning the simple concept into "the enjoyment of science class by many students comes from..." This wordiness obscures the main idea and makes the sentence harder to process quickly. Strategy tip: When choosing the clearest sentence, read each option aloud in your head. The clearest version will sound most natural and conversational while still being grammatically correct. Watch out for passive voice constructions and unnecessarily complex phrases that can often be simplified without losing meaning.

Question 14

Choose the most effective phrase to replace the bracketed words.

The witness spoke [softly and in a hesitant manner] as she described the event.

  1. softly and hesitantly (correct answer)
  2. in a soft and hesitating way
  3. with softness and hesitation
  4. soft in addition to being hesitant
Explanation: This question tests your ability to recognize and eliminate wordiness—a key skill in written expression. When you see bracketed phrases that seem unnecessarily long or awkward, look for the most concise option that preserves the original meaning. The phrase "softly and in a hesitant manner" contains unnecessary words. Both parts describe how the witness spoke, but they're expressed inconsistently—"softly" is an adverb while "in a hesitant manner" is a wordy prepositional phrase doing an adverb's job. Choice A, "softly and hesitantly," is correct because it creates parallel structure by using two adverbs that both modify "spoke." This version is concise, clear, and maintains the exact meaning of the original while eliminating wordiness. Choice B, "in a soft and hesitating way," actually makes the sentence wordier by turning both descriptions into a prepositional phrase. While "hesitating" technically works, "hesitantly" is more standard. Choice C, "with softness and hesitation," converts the descriptions into abstract nouns within a prepositional phrase, making the sentence less direct and more wordy than the original. Choice D, "soft in addition to being hesitant," is extremely wordy and awkward. It also incorrectly uses "soft" (adjective) instead of "softly" (adverb), creating a grammatical error since adjectives can't modify verbs. When revising for conciseness, look for opportunities to create parallel structure with the same type of words (like matching adverbs). The most effective revision usually eliminates unnecessary prepositional phrases and uses the most direct grammatical construction.

Question 15

Select the best replacement for the bracketed words.

After months of training, the runners felt [as though they could run forever].

  1. they could run forever. (correct answer)
  2. like they were able to run for eternity.
  3. as if forever running was possible by them.
  4. that running for a limitless time was something they could do.
Explanation: This question tests your ability to recognize concise, clear expression by eliminating unnecessary wordiness and awkward constructions. The bracketed phrase "as though they could run forever" contains redundant language. The phrase "as though" serves the same function as simply using "that" after the verb "felt." When you express a feeling or belief, you can directly state what is felt using "that" rather than the more elaborate "as though." Choice A correctly replaces the wordy original with the streamlined "they could run forever," maintaining the exact same meaning while eliminating unnecessary words. This creates the clean sentence: "After months of training, the runners felt they could run forever." Choice B uses "like they were able to run for eternity," which is unnecessarily wordy. "Were able to" is verbose compared to "could," and while "eternity" means the same as "forever," it doesn't improve the sentence. Choice C creates an awkward passive construction with "forever running was possible by them." This passive voice makes the sentence clunky and harder to follow than the direct, active phrasing. Choice D transforms the simple idea into an overly complex phrase: "that running for a limitless time was something they could do." This turns a concise thought into a verbose, bureaucratic-sounding statement. On written expression questions, always look for the choice that expresses the idea most clearly and concisely without changing the meaning. Avoid passive voice and wordy constructions when simpler alternatives convey the same message effectively.

Question 16

Select the sentence that avoids unnecessary repetition.

  1. The team celebrated its victory by singing, dancing, and cheering together. (correct answer)
  2. The team celebrated its victory by singing songs, dancing dances, and cheering cheers together.
  3. By singing, dancing, and cheering, the team celebrated a victory celebration together.
  4. In celebration of the victory, the team celebrated by singing, dancing, and cheering together.
Explanation: When you encounter questions about avoiding unnecessary repetition, you're being tested on conciseness and clarity in writing. The goal is to express ideas efficiently without redundant words or phrases that don't add meaning. Choice A presents a clean, parallel structure: "singing, dancing, and cheering." Each verb in the series is presented simply and directly, creating an effective list without any unnecessary words. The sentence flows naturally and communicates the team's celebration clearly. Choice B contains redundant phrasing with "singing songs, dancing dances, and cheering cheers." The nouns that follow each verb are completely unnecessary since singing inherently involves songs, dancing involves dances, and cheering involves cheers. This redundancy makes the sentence wordy and awkward. Choice C repeats the concept of celebration unnecessarily with "celebrated a victory celebration." The phrase "victory celebration" is redundant because "celebrated" already establishes that a celebration is taking place. Additionally, starting with the participial phrase makes the sentence structure unnecessarily complex. Choice D also contains redundant language with "In celebration of the victory, the team celebrated." The opening phrase and the verb "celebrated" express the same idea twice, creating wordiness without adding clarity or emphasis. Watch for redundancy patterns on the TACHS: repeated concepts in different forms, unnecessary modifying words, and phrases that restate what's already been said. The most concise version that maintains clarity is usually correct.

Question 17

Which choice best replaces the bold portion?

Having finished his homework, the video game console was turned on by Luis.

  1. After Luis finished his homework, he turned on the video game console. (correct answer)
  2. When finishing his homework, the video game console was on for Luis.
  3. Finishing his homework, the video game console turned on.
  4. He finished his homework then turned on the video game console.
Explanation: When you encounter a sentence with a participial phrase like "Having finished his homework," you need to check what the phrase is describing. A participial phrase must logically modify the subject that immediately follows it. In the original sentence, "Having finished his homework" is followed by "the video game console," which creates a dangling modifier. This suggests that the video game console finished the homework, which is impossible. The participial phrase should describe Luis, not the console. Choice A correctly fixes this error by restructuring the sentence with a proper subject-verb relationship: "After Luis finished his homework, he turned on the video game console." This makes it clear that Luis is performing both actions. Choice B still contains the same fundamental error as the original sentence. While it changes "Having" to "When," it maintains the illogical structure where "the video game console" appears to be finishing homework. Choice C compounds the problem by keeping "the video game console" as the subject while using "Finishing his homework" as the modifier, creating the same impossible scenario. Choice D, while grammatically acceptable, uses informal language with "then" and lacks the subordinating conjunction that would make the relationship between the two actions clearer and more sophisticated. Remember to always check that participial phrases logically modify the noun or pronoun that immediately follows them. When you spot a participial phrase at the beginning of a sentence, ask yourself: "Who or what is actually performing this action?"

Question 18

Choose the most effective replacement for the bracketed words.

[Even though it was pouring rain], Maya insisted on finishing her ten-mile run.

  1. Although it was pouring rain (correct answer)
  2. Notwithstanding the fact that it rained heavily
  3. Despite the downpour of rain that was pouring
  4. In spite of it raining in a pouring way
Explanation: This question tests your ability to identify clear, concise writing while maintaining proper grammatical relationships. When you see questions asking for "most effective replacement," look for the option that expresses the idea most directly without unnecessary words or awkward constructions. The original phrase needs to show a contrast between the rain and Maya's determination to continue running. Answer A, "Although it was pouring rain," accomplishes this perfectly. It uses a clear subordinating conjunction ("although") that immediately signals the contrasting relationship, and the phrase is concise and natural-sounding. Let's examine why the other options are less effective. Answer B, "Notwithstanding the fact that it rained heavily," is unnecessarily wordy and formal. The phrase "the fact that" adds bulk without meaning, and "notwithstanding" sounds pretentious in this context. Answer C, "Despite the downpour of rain that was pouring," contains redundant language—"downpour," "rain," and "pouring" all express the same concept, making the phrase repetitive and clunky. Answer D, "In spite of it raining in a pouring way," is grammatically awkward with its gerund construction "it raining" and the unnatural phrase "in a pouring way." For written expression questions, remember that effective writing is typically concise and clear. When multiple options express the same meaning, choose the one that does so most directly without redundancy or unnecessarily complex language. The best answer usually sounds natural when read aloud.

Question 19

Choose the phrase that best completes the sentence.

Every applicant must submit an essay, two letters of recommendation, and   by March 1.

  1. a completed form (correct answer)
  2. submission of a form completed
  3. they also have to send in a completed form
  4. and also turning in a form which is completed
Explanation: This question tests parallel structure, which means that items in a series must have the same grammatical form. When you see a list of items separated by commas and "and," check that each element follows the same pattern. The sentence lists three required items: "an essay, two letters of recommendation, and  ." The first two items are both noun phrases - "an essay" (article + noun) and "two letters of recommendation" (number + noun + prepositional phrase). To maintain parallel structure, the third item must also be a noun phrase. Choice A) "a completed form" is correct because it follows the same pattern as the other items - it's a simple noun phrase with an article, adjective, and noun. This creates smooth, balanced writing that's easy to read. Choice B) "submission of a form completed" breaks parallel structure by using a gerund phrase ("submission of...") instead of a simple noun phrase, and the word order sounds awkward. Choice C) "they also have to send in a completed form" completely destroys the parallel structure by switching to a full clause with a subject and verb, plus it creates an unclear pronoun reference with "they." Choice D) "and also turning in a form which is completed" uses a gerund phrase ("turning in") rather than a noun phrase, includes redundant words ("and also"), and uses wordy phrasing ("which is completed"). Remember: when you see lists in sentences, make each item grammatically identical. Read the list aloud - parallel items will have a natural rhythm, while non-parallel items will sound choppy or awkward.

Question 20

Select the most effective phrase to replace the bracketed words.

The movie's plot unfolded [in a way that was gradual] but thrilling.

  1. gradually (correct answer)
  2. with gradual aspect
  3. in a gradual manner of unfolding
  4. by being gradual in its way
Explanation: When you encounter bracketed phrases in written expression questions, you're being asked to identify wordiness and find the most concise, clear alternative. The key is eliminating unnecessary words while preserving the original meaning. The bracketed phrase "in a way that was gradual" is wordy and awkward. It uses seven words to express what can be said in one. Choice A, "gradually," is the most effective replacement because it's a simple adverb that directly modifies "unfolded" and maintains the sentence's meaning while eliminating redundancy. Choice B, "with gradual aspect," is awkward and unnatural. The word "aspect" is unnecessarily formal and doesn't fit the sentence flow. Choice C, "in a gradual manner of unfolding," actually makes the sentence worse by adding even more words and creating redundancy—since "unfolding" already appears in the original sentence as "unfolded." Choice D, "by being gradual in its way," is wordy and creates an unclear reference with "its way," making the sentence confusing rather than clearer. The revised sentence "The movie's plot unfolded gradually but thrilling" flows naturally and eliminates the clunky prepositional phrase while keeping the essential meaning intact. Remember this pattern: when you see wordy phrases in brackets, look for the answer choice that uses the fewest words while maintaining clarity and grammatical correctness. Often, a single adverb or adjective can replace an entire prepositional phrase, making your writing more direct and powerful.
