Change the following sentence from active to passive:
By the deadline, the students must have been submitting their assignments electronically.
Show answer & explanation
Correct answer: D
Explanation
Correct Answer: The assignments must have been being submitted electronically by the students by the deadline.
Explanation
• The given sentence is in the active voice with a modal perfect continuous form (must + have + been + verb-ing).
• To convert a sentence with a modal perfect continuous tense into the passive voice, follow this structure:
• Active: Subject + modal + have been + V-ing + Object
• Passive: Object + modal + have been being + V3 (past participle) + by + Subject
• Applying this rule: "the assignments" (object) + "must have been being submitted" + "electronically" + "by the students" (subject) + "by the deadline".
