Which sentence correctly uses a floating quantifier to describe the state of multiple servers?
"All" can "float" away from its noun and attach instead to the auxiliary verb, appearing directly after the first auxiliary ("have") rather than before the noun. Option B is correct: "The servers have all restarted successfully" — "all" floats to a position right after "have" and before the main verb "restarted". Option A places "all" in its standard pre-noun position ("All the servers"), which is also grammatical but is not the floating-quantifier pattern being tested. Options C and D place "all" after the main verb or at the sentence end, which is not a valid floating position in standard English — floating quantifiers must sit immediately after an auxiliary (or before a lone main verb in simple tenses), not after the full verb phrase.

Which sentence correctly floats the quantifier "both" in a sentence with no auxiliary verb (simple present)?
In simple tenses without an auxiliary, a floating quantifier is placed immediately before the main verb. Option B is correct: "The primary and replica databases both sync every second" — "both" floats to just before "sync". Option A places "both" in its standard pre-noun position, which is grammatical but not the floating pattern. Options C and D place "both" after the verb or at the end of the sentence, which are not valid floating positions — the quantifier must sit directly before the main verb (in simple tenses) or directly after the first auxiliary (in compound tenses), never after the verb phrase or clause-finally.
3 / 5
Which sentence correctly floats "each" to add emphasis on individual, separate action in a code review context?
"Each" floats to a position right after the modal auxiliary "must" and before the main verb "approve". Option B is correct: "The reviewers must each approve..." Option A places "each" in its standard pre-noun distributive position ("Each reviewer"), which is grammatical but changes the subject from plural to singular-distributive rather than demonstrating floating. Option C places "each" after the main verb and before its object, which is not a valid floating position — this creates an ungrammatical, confusing string ("approve each the pull request"). Option D places "each" before the modal "must" rather than after it — floating quantifiers attach after the first auxiliary/modal, not before it.
4 / 5
Which sentence demonstrates the correct floating position of "all" in a sentence with a modal + perfect construction ("must have")?
When there are two auxiliaries ("must have"), the floating quantifier attaches after the first auxiliary that carries the main grammatical weight closest to the verb — in practice, native-speaker usage places "all" after the full auxiliary chain and directly before the main verb: "must have all passed". Option B is correct. Option A places "all" between "must" and "have", which is grammatical in some dialects but far less natural for most speakers, who prefer the quantifier closest to the main verb it modifies. Option C places "all" before the modal "must", which is not a valid floating position. Option D places "all" after the main verb "passed", which is also invalid — floating quantifiers never follow the main verb.
5 / 5
Which sentence contains an incorrect floating-quantifier placement that a careful editor should flag in a status report?
Option C is incorrect: "have been all resolved" places "all" after both auxiliaries ("have been"), but the standard floating position is immediately after the first auxiliary, not after the full auxiliary chain when there are only two elements — the natural, correct order is "have all been resolved". This kind of misplacement is a common non-native error. Option A ("have both been redeployed") is correct — "both" floats immediately after the single relevant auxiliary "have". Option B ("all return") correctly floats "all" before the simple-present main verb. Option D ("were both assigned") correctly floats "both" right after the auxiliary "were". The general rule: the floating quantifier goes right after the first auxiliary verb, before any remaining auxiliaries or the main verb.
