  1. Which choice completes the sentence with the correct punctuation?
    Answer: Des Moines, Iowa; When you encounter a series with complex items that already contain commas, you need to use semicolons as the primary separator to avoid confusion. This is called a "complex series" or "series with internal punctuation." In this sentence, you're dealing with a list of cities and their states. Since each item in the series contains a comma (Chicago, Illinois; Madison, Wisconsin), you must use semicolons to separate the main items. The pattern is: "City, State; City, State; City, State." Choice A is correct because "Des Moines, Iowa;" follows the established pattern perfectly. It includes the comma between city and state, followed by a semicolon to separate it from the next item in the series. Even though "Des Moines, Iowa" is the last location before "and Minneapolis, Minnesota," it still needs the semicolon to maintain parallel structure throughout the series. Choice B fails because it uses only a comma, breaking the semicolon pattern established in the rest of the series. Choice C incorrectly places the semicolon between the city and state rather than between the city-state pairs. Choice D omits the essential comma between "Des Moines" and "Iowa" while keeping the semicolon in the wrong position. Study tip: When you see a series where individual items contain commas, automatically switch to semicolons as your main separators. Keep the internal punctuation (commas within items) and use semicolons between items consistently throughout the entire series, even before the final "and."
  2. Which choice completes the sentence with the correct idiomatic preposition?
    Answer: on This question tests your knowledge of idiomatic prepositions—specific prepositions that must be used with certain verbs to create standard English expressions. When you encounter these questions, focus on which preposition naturally pairs with the given verb. The verb "insist" requires the preposition "on" when followed by a gerund (an -ing verb form). "Insist on" is the correct idiom meaning to demand or require something firmly. In this sentence, the committee is demanding that they review all proposals, so "insisted on reviewing" creates the proper meaning and follows standard English usage. Let's examine why the other options don't work. Choice B ("in") doesn't form a standard idiom with "insist"—we don't say "insist in doing" something. Choice C ("about") changes the meaning entirely; "insist about" would suggest the committee is being persistent in talking about reviewing, rather than demanding to actually do the reviewing. Choice D ("for") also fails to create the correct idiom—"insist for reviewing" is not standard English and sounds awkward. The key strategy for idiomatic preposition questions is to trust your ear for what sounds natural in English, but also memorize common verb-preposition combinations. Some verbs like "insist," "depend," and "consist" have specific prepositions they must pair with ("on," "on," and "of" respectively). When studying, create a list of common idioms you encounter in practice questions, as these patterns appear frequently on standardized tests.
  3. Which choice properly punctuates the introductory phrase?
    Answer: To complete the study, the researchers collected data from over 500 participants. When you encounter questions about punctuating introductory phrases, focus on identifying where the introductory element ends and the main clause begins. Introductory phrases typically need to be separated from the main clause with a comma. In this sentence, "To complete the study" is an infinitive phrase that introduces the main action. This introductory phrase tells us the purpose or reason for what follows. The main clause is "the researchers collected data from over 500 participants," which contains the subject (researchers) and the main verb (collected). Choice A correctly places a comma after "study," properly separating the introductory phrase from the main clause. This follows the standard rule that introductory phrases of four or more words should be followed by a comma. Choice B incorrectly places the comma after "researchers," which splits the subject from its verb "collected." This creates an awkward pause in the middle of the main clause rather than separating the introduction from the main idea. Choice C places a comma after "complete," which breaks up the introductory phrase itself. The phrase "To complete the study" should remain intact as a single unit of meaning. Choice D puts the comma after "collected," separating the verb from its object "data." This disrupts the flow of the main clause and creates an unnatural pause. Remember: introductory phrases function as a unit and need a comma to separate them from the main clause. Look for where the introduction ends and the main subject-verb action begins—that's where your comma belongs.
  4. Which choice corrects the pronoun error in the sentence?
    Answer: they When you encounter pronoun agreement questions, focus on identifying what the pronoun refers to and whether the subject is singular or plural. This sentence uses "neither...nor," which creates a compound subject that follows specific agreement rules. The correct answer is B) "they" because with "neither...nor" constructions, the verb and any pronouns agree with the subject closest to them. Here, "the other committee members" (plural) is closer to the pronoun than "Marcus" (singular), so you need the plural pronoun "they." Let's examine why the other choices fail: A) "he" is incorrect because it's singular and would only refer to Marcus, ignoring the plural "committee members" that's closer to the pronoun. C) "him" has two problems—it's singular (same issue as choice A) and it's an object pronoun, but you need a subject pronoun here since it's performing the action of finishing the report. D) "them" is plural, which correctly matches "committee members," but it's an object pronoun when you need a subject pronoun for this sentence position. The key distinction is between subject pronouns (I, you, he, she, it, we, they) and object pronouns (me, you, him, her, it, us, them). Subject pronouns perform actions, while object pronouns receive actions. Remember this pattern: in "neither...nor" and "either...or" constructions, always make your verb and pronouns agree with whichever subject is closest to them. Also, double-check whether you need a subject or object pronoun based on the pronoun's role in the sentence.
  5. Which choice completes the text so that it conforms to the conventions of Standard English?
    Answer: her This question tests pronoun case, distinguishing between subjective and objective forms. The pronoun serves as the object of 'contact,' requiring the objective case 'her' to refer to the intern. Choice B correctly provides this objective pronoun. Choice A uses the subjective 'she,' which cannot function as an object, Choice C's reflexive 'herself' is unnecessary without emphasis on self-action, and Choice D's possessive 'hers' does not fit the non-possessive context. Remember that pronouns after action verbs or prepositions typically need the objective case, like 'him' or 'her,' rather than subjective forms like 'he' or 'she.'
  6. Which revision eliminates the double negative?
    Answer: The athletes could scarcely believe their record-breaking time. When you encounter questions about double negatives, you're being tested on your ability to recognize when two negative words cancel each other out, creating an unintended meaning. The original sentence contains "could not" and "scarcely" — both negative expressions. When combined, they create a double negative that literally means the athletes could believe their time, which is the opposite of the intended meaning. Choice A correctly eliminates one negative word ("not"), leaving only "scarcely," which properly conveys that the athletes had difficulty believing their time. This maintains the intended meaning while using standard English grammar. Choice B replaces "scarcely" with "hardly" but keeps both negatives ("could not" + "hardly"), so the double negative problem persists. Choice C makes the error even worse by adding a third negative word ("never"), creating a triple negative. Choice D compounds the problem by including three negatives: "couldn't" (contraction of "could not"), "scarcely," and "not." The key insight is that words like "scarcely," "hardly," "barely," and "seldom" already carry negative meaning, so they don't need additional negative words like "not" or "never" to express a negative idea. Strategy tip: When you see sentences with words like "scarcely," "hardly," or "barely," scan for other negative words. If you find multiple negatives, look for the answer choice that removes all but one negative element while preserving the intended meaning.
  7. Which choice completes the text so that it conforms to the conventions of Standard English?
    Answer: to keep This question tests the use of infinitives to express purpose. The phrase 'to keep the temperature steady' acts as an infinitive of purpose, explaining why the students check the thermometer, fitting the procedural context after the semicolon. Choice A, 'to keep,' correctly introduces this purpose clause. Choice B's 'keeping' creates a participial phrase that dangles without clear attachment, Choice C's 'kept' introduces a past participle that disrupts the present tense sequence, and Choice D's 'keep' is a bare infinitive that lacks the 'to' needed for purpose. In procedural writing, infinitives of purpose are useful for clearly stating the reason for an action without ambiguity.
  8. Which choice completes the text so that it conforms to the conventions of Standard English?
    Answer: them This question tests pronoun case after prepositions. The pronoun follows the preposition 'to,' which requires the objective case 'them' to refer to 'the committee members.' Choice A 'they' is subjective case (used for subjects), choice C 'their' is possessive, and choice D 'theirs' is possessive pronoun without a noun. The sentence structure is: send [the budget] to [them], where 'them' is the object of the preposition. Remember that pronouns after prepositions (to, from, with, for, etc.) always take the objective case: me, him, her, us, them.
  9. Which choice completes the sentence with the correct comparative form?
    Answer: more innovative When comparing exactly two items, you need to use the comparative form of adjectives, not the superlative form. This distinction is crucial for standard English grammar. Choice A ("more innovative") is correct because it uses the proper comparative form when contrasting two proposals. For adjectives with three or more syllables like "innovative," you form the comparative by adding "more" before the adjective. Since the sentence explicitly states "of the two proposals," you're making a direct comparison between exactly two items. Choice B ("most innovative") is incorrect because "most" creates the superlative form, which you use when comparing three or more items. Using the superlative for just two items violates standard grammar rules. Choice C ("the most innovative one") has the same problem as B—it uses the superlative form inappropriately. Adding "the" and "one" doesn't fix the fundamental issue that "most" is wrong for comparing two items. Choice D ("innovativest") attempts to create a superlative by adding "-est" to "innovative," but this is grammatically incorrect. Long adjectives (typically three or more syllables) don't take the "-est" ending; they use "most" for superlatives and "more" for comparatives. Study tip: Remember the "rule of two versus three or more"—comparative forms (better, more intelligent) for two items, superlative forms (best, most intelligent) for three or more. When you see "of the two" in a sentence, immediately look for comparative forms in the answer choices.
  10. Which choice most effectively avoids wordiness?
    Answer: Because the meeting was postponed, the team had additional time to finish the report. When you encounter a question about avoiding wordiness, you're being tested on your ability to identify concise, clear writing that eliminates unnecessary words and phrases without changing the meaning. The most effective revision is choice A because it eliminates the wordy phrase "due to the fact that" and replaces it with the simple, direct word "because." It also removes the redundant phrase "until a later date" since "postponed" already implies delay to a future time. This creates a clean, straightforward sentence that maintains the original meaning while cutting excess words. Choice B makes the sentence even wordier by using unnecessarily formal phrases like "owing to the circumstance that" and "possessed extra time with which to." These additions create pompous, bureaucratic language that obscures rather than clarifies meaning. Choice C creates an awkward construction with "The meeting having been postponed...led to the team having extra time." This participial phrase structure is clunky and harder to follow than a simple cause-and-effect sentence. Choice D commits a grammatical error by using both "since" and "therefore" to show the cause-and-effect relationship. This creates redundancy—you need only one connector, not both. Additionally, it keeps the wordy "until a later date." Strategy tip: Look for common wordy phrases that can be simplified: "due to the fact that" becomes "because," "in order to" becomes "to," and "at this point in time" becomes "now." The most concise option that preserves meaning is usually correct.
  11. Which choice completes the text so that it conforms to the conventions of Standard English?
    Answer: show This question tests subject-verb agreement with compound subjects joined by correlative expressions. The subject is "The data from the sensors, in addition to the weather records," but "in addition to" doesn't create a true compound—the main subject is "The data," which is plural, requiring the plural verb "show" (Choice A). Choice B "shows" is singular and doesn't agree with the plural "data." Choice C "showing" creates a fragment without a main verb. Choice D "has shown" uses singular "has" which doesn't match the plural subject. Remember that "data" is traditionally plural (though sometimes treated as singular in informal usage), and phrases like "in addition to" don't change the number of the main subject.
  12. Which choice completes the text so that it conforms to the conventions of Standard English?
    Answer: they This question tests pronoun reference and number agreement. We need a pronoun that refers back to "two Roman coins," which is plural, so we need the plural pronoun "they" (Choice B). The pronoun must logically refer to the coins that were placed in labeled trays for later examination. Choice A "it" is singular and can't refer to two coins. Choice C "him" is masculine singular and doesn't match the antecedent. Choice D "one" is singular and creates an unclear reference. When choosing pronouns, always identify the antecedent first and ensure your pronoun matches it in both number and gender.
  13. Which choice completes the text so that it conforms to the conventions of Standard English?
    Answer: them This question tests pronoun case and reference, requiring an objective pronoun to serve as the object of 'address.' The antecedent is the plural 'questions' implied from 'ask questions,' so 'them' correctly refers to these questions as the things the speaker will address. Choice A 'they' is nominative and cannot function as an object; C 'their' is possessive, which would incorrectly suggest ownership; and D 'theirs' is a possessive pronoun that doesn't fit the object role. In pronoun questions, always determine the grammatical role—such as subject or object—and match the case accordingly while ensuring clear reference to the antecedent.
  14. Which choice completes the text so that it conforms to the conventions of Standard English?
    Answer: it This question tests pronoun reference with clear antecedents. The pronoun must refer to "the trilobite" (the subject of the clause), which is singular and non-human, so we need "it" (Choice A). The sentence structure makes clear that the trilobite was stored because the trilobite was fragile. Choice B "they" is plural and doesn't match the singular antecedent. Choice C "he" implies human gender. Choice D "those" is plural and demonstrative, not matching the singular trilobite. When a pronoun immediately follows its antecedent in the same clause, ensure number agreement and use the appropriate pronoun for non-human objects.
  15. Which choice completes the text so that it conforms to the conventions of Standard English?
    Answer: was This question tests subject-verb agreement with compound subjects joined by 'along with.' The true subject is 'the set of samples,' which is singular—the phrase 'along with the control solution' is a parenthetical addition that doesn't change the subject's number. Since 'set' is singular and the context describes a past event (the report explains what happened), we need the singular past tense verb 'was.' Choice A 'were' is plural, choice B 'are' is present tense, and choice D 'have been' is present perfect plural. When you see phrases like 'along with,' 'as well as,' or 'together with,' remember they don't create compound subjects—focus on the main subject before these phrases.
  16. Which choice completes the text so that it conforms to the conventions of Standard English?
    Answer: changes This question tests subject-verb agreement with compound subjects. The subject 'cluster' is singular, and 'as well as periodic flares' acts as an additive phrase that does not make the subject plural, so a singular verb is needed. Choice B, 'changes,' correctly matches in number and uses simple present for a general truth. Choice A uses plural 'change,' mismatching the subject, Choice C introduces present continuous 'are changing' unnecessarily, and Choice D's present perfect 'have changed' shifts tense without justification. In agreement questions, treat phrases like 'as well as' as nonessential and base the verb on the main subject's number.
  17. Which choice completes the text so that it conforms to the conventions of Standard English?
    Answer: we This question tests pronoun case in subject position. After "asked that," we have a noun clause where the pronoun serves as the subject of the verb "focus," so we need the subjective case "we" (Choice A). Choice B "us" is objective case and can't be the subject of a verb. Choice C "our" is possessive and doesn't fit grammatically. Choice D "ours" is also possessive and creates an incomplete sentence. When a pronoun is the subject of a verb (even in a subordinate clause), always use the subjective case (I, we, he, she, they) regardless of what comes before the clause.
  18. Which choice eliminates the faulty comparison?
    Answer: The taste of fresh herbs is better than the taste of dried ones. When you encounter a sentence that sounds awkward or unclear, look for faulty comparisons—instances where two different types of things are being compared inappropriately. In this question, the original sentence compares "the taste of fresh herbs" to "dried ones" (dried herbs), which creates a logical mismatch between a quality (taste) and the herbs themselves. The correct answer is C because it creates a proper parallel comparison between "the taste of fresh herbs" and "the taste of dried ones." Both sides of the comparison now refer to the same type of thing—taste—making the sentence logically sound and clear. Let's examine why the other options fail: Choice A changes the sentence structure entirely but doesn't address the core comparison issue, as it's comparing "fresh herbs" to "dried ones" rather than their tastes specifically. Choice B maintains the faulty comparison by contrasting "fresh herbs' taste" with "dried ones" (the herbs themselves) rather than their taste. Choice D creates an even more awkward construction with "Better than dried ones, fresh herbs have taste," which suggests dried herbs have no taste at all and places the comparison in a confusing position. The key strategy here is to identify what's actually being compared and ensure both sides of the comparison are the same type of thing. When you see comparison words like "better than," "more than," or "superior to," check that you're comparing apples to apples, not apples to the taste of oranges.
  19. Which choice completes the text so that it conforms to the conventions of Standard English?
    Answer: remained This question tests verb tense consistency within a narrative. The chemist "explained" (past tense) and the demonstration occurred in the past, so we need the past tense "remained" (Choice B) to maintain consistency. Choice A "remain" is present tense and doesn't match the past context. Choice C "remaining" creates a fragment without a main verb. Choice D "remains" is present tense and contradicts the past-tense framework established by "explained." When a passage establishes a past-tense narrative frame, maintain that tense throughout unless there's a clear reason to shift.
  20. Which choice completes the text so that it conforms to the conventions of Standard English?
    Answer: is This question tests subject-verb agreement with compound subjects joined by 'plus.' Like 'along with,' the word 'plus' creates a parenthetical addition rather than a true compound subject—the main subject is 'A list,' which is singular. Therefore, we need the singular verb 'is' to agree with 'list.' Choice A 'are' is plural, choice B 'were' is past tense plural, and choice D 'have been' is present perfect plural. When determining subject-verb agreement, ignore interrupting phrases introduced by plus, along with, as well as, or in addition to—they don't change the number of the subject.
