Which sentence correctly uses "as if" to describe a hypothetical (not literally true) comparison during an incident?
"The dashboard behaved as if the cache were completely empty, even though it wasn't" is correct: "as if" + subjunctive "were" signals an unreal comparison — the cache wasn't actually empty. Option B awkwardly adds a redundant clause after the correct core. Option C substitutes "like", which is used for real similarity or informally as a conjunction, and mismatches tense. Option D drops "if", leaving an incomplete and ungrammatical phrase.

Choose the sentence that correctly uses "as though" (interchangeable with "as if") in a code review comment.
"This function reads as though it were designed for a single-threaded environment" is correct: "as though" functions exactly like "as if", introducing a hypothetical impression with subjunctive "were". Option B uses indicative "is", which loses the hypothetical, impression-based nuance. Option C is ungrammatical, mangling the clause structure. Option D incorrectly reorders "it" and "though".
3 / 5
Select the sentence that correctly contrasts real similarity ("like") with unreal comparison ("as if") in the same report.
"It looked like a memory leak; it behaved as if allocations were never released" is correct: "like" precedes a noun phrase for real resemblance, while "as if" introduces a full clause for the hypothetical behavior. Option B swaps the two incorrectly, using "as if" before a bare noun phrase. Option C combines both markers redundantly. Option D omits both markers where they're needed and misplaces "like" at the end.
4 / 5
Which sentence correctly uses "as if" with a past perfect verb to describe an unreal comparison about something prior to the reference time?
"...as if the retry had fired before the timeout" is correct: past perfect after "as if" places the hypothetical event even earlier than the already-past main clause. Option B incorrectly switches to present tense "fires". Option C uses the ungrammatical bare -ing form without an auxiliary. Option D scrambles the word order of the fixed phrase "as if".
5 / 5
Choose the sentence that correctly avoids the common error of using indicative "was" instead of subjunctive "were" after "as if" in formal technical writing.
"The service responded as if it were under a denial-of-service attack" is correct: formal, precise technical writing favors the subjunctive "were" after "as if" regardless of the subject's number. Option B uses the more casual "was", acceptable informally but not the preferred formal register. Option C incorrectly reorders "if" and "as". Option D uses the bare form "be", which is not the correct subjunctive pattern here.
