Question

• A. The reagents have been double-checked by the laboratory by dawn.
• B. The reagents will have been double-checked by the laboratory by dawn.
• C. The reagents will be double-checked by the laboratory by dawn.
• D. The reagents would have been double-checking by the laboratory by dawn.

Answer 1

Answer:

B. The reagents will have been double-checked by the laboratory by dawn.

• The reagents will have been double-checked by the laboratory by dawn. • The active sentence is in the Future Perfect tense (will have double-checked). • To convert it to passive voice, the object (The reagents) becomes the subject, and the verb structure updates to will have been + past participle (will have been double-checked).
