Will she have submitted her thesis before mine is?
Show answer & explanation
Correct answer: B
Explanation
Correct Answer
Will her thesis have been submitted before mine is?
Explanation
The original sentence is an interrogative sentence in the Future Perfect tense ("Will... have submitted"). When converting a future perfect active sentence into the passive voice, the structural formula required is "Will + object + have been + past participle (V3)". The object of the active clause is "her thesis," which must become the subject of the passive clause. Applying this rule yields the correct structure: "Will her thesis have been submitted before mine is?".
The alternate choices break structural or tense constraints. Option 1 shifts the tense incorrectly into the simple future passive ("will... be submitted"). Option 3 is grammatically broken because it leaves out the mandatory auxiliary verb "have" before "been." Option 4 drops the auxiliary verbs completely and incorrectly replaces the possessive pronoun "mine" with the objective pronoun "me" at the end.
Key Point
Voice conversion demands strict maintenance of the original tense structure. Because the active question uses the future perfect tense, its passive counterpart must incorporate "have been" to remain grammatically accurate and preserve the original timeline of the action.
