Question 1
During an inspection, the inspector checked all three locks on all six doors.
Which sentence most precisely reports what the inspector did?
- The inspector checked any lock on every one of the six doors.
- The inspector checked every locks on each of the six doors.
- The inspector checked every lock on each of the six doors. (correct answer)
- The inspector checked some lock on each of the six doors.
Explanation: When selecting determiners like "every," "each," "any," and "some," you need to match them carefully to their intended meaning and ensure grammatical agreement with the nouns they modify.
The passage tells us the inspector checked all locks on all doors — meaning every single lock and every single door, with no exceptions. Choice C captures this perfectly: "every lock on each of the six doors." Both "every" and "each" express totality (all members of a group, individually considered), "lock" is correctly singular after "every," and the six doors are fully accounted for.
Looking at the wrong answers reveals common traps. Choice A uses "any," which is a problem — "any" implies an unspecified or indefinite selection ("did he check any locks?"), not a complete, exhaustive check. It fails to convey that all locks were inspected. Choice B gets the determiner right ("every") but pairs it with the plural noun "locks" — this is a subject-verb and determiner agreement error. "Every" always takes a singular noun: every lock, never every locks. Choice D uses "some lock," which directly contradicts the passage. "Some" means a portion, not all — it would imply the inspector skipped certain locks, which is the opposite of what happened.
A useful rule to remember: "every" and "each" always take singular nouns, even though they refer to a group. On grammar exams, answer choices that pair "every" or "each" with a plural noun are always wrong. Also train yourself to distinguish "any/some" (indefinite or partial) from "every/each" (complete and exhaustive) — test writers frequently use these interchangeably as distractors.
Question 2
All four appointment dates remain available. A client may freely choose one of them but must provide an unspecified amount of advance notice before changing the selection.
Which pair of determiners best completes the sentence? "The client may select date but must give us notice before changing it."
- some; any
- every; any
- any; some (correct answer)
- each; every
Explanation: When a question asks you to choose determiners, think carefully about two things: countability (does the noun refer to something countable or uncountable?) and scope (are you selecting from options, or describing quantity?). These two factors working together will guide you to the right pairing.
In the sentence, "date" is a countable noun — the client picks one specific date from available options. "Notice" is an uncountable noun — it refers to an indefinite amount of advance warning, not individual units. The determiner any works perfectly with singular countable nouns to signal free choice among options ("select any date" means whichever one you prefer). The determiner some works with uncountable nouns to indicate an unspecified quantity ("give us some notice" means an indeterminate amount). Together, any + some captures exactly what the passage describes: open choice of date, plus an unspecified but required amount of notice. That makes C the correct answer.
Looking at the wrong options: A (some; any) reverses the logic — "some date" suggests a vague, partial selection rather than free choice, and "any notice" implies that even zero notice would qualify, which contradicts the passage's requirement. B (every; any) fails because "every date" means all dates simultaneously, not a single selection, and "any notice" carries the same zero-notice problem. D (each; every) similarly treats "each date" as referring to all dates individually rather than offering a choice, and "every notice" is grammatically awkward with an uncountable noun.
Your takeaway: when pairing determiners, always identify whether each target noun is countable or uncountable first — that single distinction eliminates most wrong answers immediately.
Question 3
There were three editors and four chapters. All three editors reviewed all four chapters.
Which sentence expresses the complete pattern of reviews without weakening it?
- Every editor reviewed some chapter in the manuscript.
- Some editor reviewed every chapter in the manuscript.
- Every editors reviewed each chapter in the manuscript.
- Each editor reviewed every chapter in the manuscript. (correct answer)
Explanation: When a question asks which sentence "expresses the complete pattern" of a described relationship, you're being tested on quantifier scope — how words like every, each, some, and all distribute meaning across a sentence. The key question to ask yourself is: does this sentence account for every member of both groups?
The passage tells us each of three editors reviewed each of four chapters — a total, exhaustive relationship. D, "Each editor reviewed every chapter," captures exactly this: it guarantees that no editor is left out (each editor) and no chapter is left out (every chapter). This is the only option that fully preserves the complete 3×4 review matrix.
Here's why the other choices fall short. A says "every editor reviewed some chapter," which means each editor reviewed at least one chapter — possibly different ones, possibly not all four. The word some weakens the claim significantly. B says "some editor reviewed every chapter," which actually allows for only one editor doing all the reviewing, leaving the other two unaccounted for entirely. C is grammatically incorrect — "every editors" is a subject-verb agreement error, since every takes a singular noun (editor, not editors), making C invalid on grammatical grounds alone before you even consider its meaning.
A useful strategy: treat every/each as your "all-inclusive" quantifiers and some as your "at least one" quantifier. When a passage describes a universal, exhaustive relationship, you need every or each on both sides of the sentence. If either side uses some, the claim is weakened.
Question 4
A policy applies whenever a complaint is submitted, regardless of which complaint it is. Reviewers must separately examine all allegations contained in that complaint.
Which sentence most precisely states the policy?
- If every complaint is submitted, reviewers must examine each allegation it contains.
- If any complaint is submitted, reviewers must examine each allegation it contains. (correct answer)
- If some complaints are submitted, reviewers must examine each allegation they contain.
- If any complaint is submitted, reviewers must examine some allegation it contains.
Explanation: When a question asks you to "precisely state a policy," you're really being tested on quantifier logic — the words every, any, some, and each carry very different logical meanings, and swapping them changes what the policy actually says.
The original passage establishes two things: the policy triggers for any single complaint (not just all of them collectively), and all allegations in that complaint must be examined. Option B captures this perfectly — "if any complaint is submitted" means the rule fires whenever even one complaint exists, and "each allegation it contains" means every allegation in that specific complaint gets examined. This matches the source passage exactly.
Here's why the other options fail. Option A uses "if every complaint is submitted," which implies the policy only activates when the entire set of possible complaints has been filed — a much stronger condition that nearly never triggers. That's the opposite of the intended meaning. Option C says "if some complaints are submitted," which is vague and suggests a subset, leaving unclear how many are needed; it also shifts to "they contain," implying multiple complaints must exist before the rule applies. Option D correctly uses "if any complaint is submitted" to trigger the rule, but then weakens the examination requirement to "some allegation" — meaning reviewers could ignore most allegations and still technically comply. That directly contradicts "all allegations must be examined."
A useful strategy: when evaluating quantifiers, mentally substitute extreme cases. Ask, "Does this hold for just one instance? Does it require all instances?" Words like every, any, some, and each are precision tools — treat them as technical vocabulary, not interchangeable synonyms.
Question 5
A presenter is pointing to several conclusions on a slide. All of them come from one longitudinal study.
Which pair of determiners correctly completes the sentence? " conclusions, rather than the tentative claim in the appendix, arise from longitudinal study."
- This; this
- These; this (correct answer)
- These; these
- This; these
Explanation: When choosing determiners like this and these, the key is matching the determiner to the number of the noun it modifies — singular nouns take this, while plural nouns take these.
In this sentence, the first blank modifies "conclusions," which is plural, so you need these. The second blank modifies "longitudinal study," which is singular (the passage specifies there is one study), so you need this. That gives you "These conclusions... arise from this longitudinal study" — which is choice B, the correct answer.
Looking at the distractors: A (This; this) incorrectly uses this with the plural noun "conclusions." You'd only use this before a singular noun like "conclusion." C (These; these) gets the first blank right but misapplies these to "longitudinal study," which is a single study — these would imply multiple studies, contradicting the passage context. D (This; these) makes the opposite error from B: it pairs a singular determiner with a plural noun in the first blank, and a plural determiner with a singular noun in the second — both slots are wrong.
A common trap here is focusing only on the grammatical rule while ignoring the passage context. Even if you correctly identify that "these" pairs with plurals, you might carelessly apply it to "study" without re-reading that there is only one study mentioned. Always let the passage anchor your number decisions — the content tells you how many, and the grammar rule tells you which determiner to use.
Question 6
Five specimens were tested. Four passed the test, and one failed.
Which sentence accurately states that all specimens were tested while avoiding the claim that all of them passed or all of them failed?
- Every specimen was tested, but not every specimen passed. (correct answer)
- Each specimen was tested, but every specimen failed.
- Some specimens were tested, but not every specimen failed.
- Every specimen was tested, and each specimen passed.
Explanation: When a question asks you to accurately reflect a passage's details using quantifiers like every, each, and some, you need to think carefully about what each word actually claims. "Every" and "each" assert that something is true for all members of a group without exception, while "some" means only a portion.
The passage tells you five specimens were tested — all five — and that four passed while one failed. So any accurate summary must confirm that all were tested, while acknowledging that the outcomes were mixed (not universal passes or universal failures). Choice A does exactly this: "Every specimen was tested" correctly captures 100% participation, and "not every specimen passed" elegantly acknowledges that at least one failed — without overstating how many. This matches the passage perfectly.
Choice B fails because its second clause — "every specimen failed" — directly contradicts the passage. Four specimens passed, so claiming all failed is factually wrong. Choice C introduces a different error: "Some specimens were tested" implies only a portion were tested, which contradicts the passage's clear statement that all five were tested. Choice D gets the first clause right but ruins it with "each specimen passed," which would mean all five passed — again contradicting the one specimen that failed.
The trap here is that B and D use confident, all-inclusive language (every, each) in ways that sound authoritative but are factually inaccurate. C goes the opposite direction, using some to falsely limit what the passage confirms.
Study tip: When evaluating quantifier questions, mentally check each clause independently — a sentence with two clauses can be half right and still be entirely wrong.
Question 7
An archive contains seven folders. Each folder must have one authorization sheet signed specifically for that folder.
Which sentence correctly expresses the requirement?
- Each of the seven folders requires its own signed authorization sheet. (correct answer)
- Every one of the seven folders require their own signed authorization sheet.
- Each of the seven folders require their own signed authorization sheet.
- Each of the seven folder requires its own signed authorization sheet.
Explanation: When a question tests subject-verb agreement with distributive pronouns like each and every, you need to identify the grammatical subject, determine whether it's singular or plural, and then check that the verb and any pronouns match it. "Each" and "every" always take singular verbs and singular pronouns, even when they refer to multiple items.
Option A is correct because "each of the seven folders" uses a singular subject ("each"), which correctly pairs with the singular verb "requires" and the singular pronoun "its." The noun inside the prepositional phrase ("folders") doesn't control the verb — "each" does.
Option B fails on two counts. "Every one" is singular, so it demands "requires," not "require." Additionally, "their" is a plural pronoun that clashes with the singular subject — a pronoun agreement error on top of the subject-verb error.
Option C makes the same pronoun mistake as B. Even though "each" correctly introduces the subject, "require" is plural (wrong verb) and "their" is plural (wrong pronoun). Two errors for the price of one.
Option D contains a subtle noun error: "each of the seven folder" should read "folders." When items follow "of the," they must be plural to reflect the group being divided. The verb "requires" and pronoun "its" are actually correct here, but the singular "folder" makes the sentence grammatically broken.
A useful rule of thumb: whenever you see each or every, mentally substitute "every single one" — that reminder keeps you anchored to singular agreement throughout the sentence.
Question 8
Investigators recovered several primary files. However, they found no backup copies at all.
Which pair of determiners most accurately completes the report? "Investigators recovered primary files, but they did not locate backup copies."
- any; some
- some; any (correct answer)
- every; some
- some; some
Explanation: When choosing between some and any, the key is polarity: some belongs in affirmative (positive) contexts, while any belongs in negative contexts and questions. Keeping this rule in mind makes questions like this straightforward.
The passage tells us two things: files were recovered (positive result), and backup copies were not found (negative result). The correct sentence needs to reflect both realities. Answer B — "some; any" — does exactly this. "Some primary files" confirms a positive recovery, and "did not locate any backup copies" pairs any with the negative verb phrase did not locate, which is its natural home.
Here's why each wrong choice fails. A (any; some) reverses the polarity entirely — any would appear in the affirmative clause where some is needed, and some would follow the negative verb where any is required. This contradicts how these determiners function. C (every; some) replaces the first blank with every, which means "all without exception." The original passage doesn't claim every possible primary file was recovered — only that some were — so every overstates the finding. Additionally, some in the second blank still conflicts with the negative construction. D (some; some) gets the first blank right but fails at the second: "did not locate some backup copies" is grammatically awkward and non-standard in English; negatives require any, not some.
A handy rule of thumb: scan the verb phrase in each clause first. If it's negative (did not, couldn't, never), choose any. If it's affirmative, choose some.
Question 9
The writer is referring to four revised manuals. Every manual contains a different appendix.
Which sentence uses the demonstrative and distributive expression with correct number agreement?
- This revised manuals for the devices each include a different appendix.
- These revised manuals for the devices each includes a different appendix.
- These revised manuals for the devices each include a different appendix. (correct answer)
- Each of these revised manuals for the devices include a different appendix.
Explanation: When a question tests both demonstrative pronouns and subject-verb agreement, you need to evaluate two things simultaneously: does the demonstrative match the noun in number, and does the verb agree with the true subject?
Here, you're referring to four manuals — a plural noun — so the demonstrative must be plural. "This" is singular and pairs only with singular nouns, while "these" is plural and correctly pairs with "manuals." That immediately eliminates any option using "this" with a plural noun.
Now for the verb. The subject is "these revised manuals" (plural), and the distributive word "each" functions as an adverb here — it modifies how the action is distributed across the subjects, but it does not change the grammatical subject. The plural subject "manuals" still governs the verb, so you need the plural verb form "include," not the singular "includes." Option C — These revised manuals for the devices each include a different appendix — correctly uses the plural demonstrative "these," keeps the plural verb "include," and uses "each" as a distributive adverb. This is your answer.
A fails immediately because "this" is singular but "manuals" is plural — a demonstrative-noun mismatch. B has the right demonstrative ("these") but wrongly uses "includes," treating "each" as if it were the subject and forcing singular agreement. D restructures "each" as the subject of the clause ("Each of these..."), which does require a singular verb — but "include" is plural, so D has the opposite problem from B: the right structure would demand "includes."
Remember: when "each" follows a plural subject, it's an adverb — the plural subject still controls the verb.
Question 10
The researcher refers to one body of evidence and to two specific claims made in an earlier article.
Which pair of determiners correctly completes the sentence? " evidence, even when considered alongside the earlier observations, does not support two claims."
- These; this
- This; this
- These; these
- This; these (correct answer)
Explanation: When choosing between this and these, you need to match the determiner to the number (singular or plural) of the noun it modifies. This pairs with singular nouns; these pairs with plural nouns.
Look at the first blank: it modifies evidence. Even though the passage mentions "one body of evidence," the word evidence itself is an uncountable noun — it has no plural form and always takes singular agreement. So the first blank requires this, not these.
Now the second blank: it modifies two claims. The word two tells you immediately that claims is plural here, so you need these to match that plural noun.
That gives you this evidence and these two claims — which is answer D.
Here's why the other options fall short. A (These; this) gets both blanks backwards — these evidence is grammatically wrong because evidence is uncountable and can't be pluralized, and this two claims incorrectly applies a singular determiner to a plural noun. B (This; this) correctly handles evidence in the first blank, but this two claims is wrong because two claims is explicitly plural. C (These; these) correctly handles claims in the second blank, but these evidence fails because uncountable nouns don't take plural determiners.
A useful rule of thumb: before choosing this or these, ask two quick questions — Can this noun be counted and pluralized? and Does the context signal singular or plural? Uncountable nouns like evidence, information, and research will always need this, regardless of context.
