Change the following sentence into the Active form.
The intricate design will have been conceived by a team of engineers.
Show answer & explanation
Correct answer: C
Explanation
The original sentence, "The intricate design will have been conceived by a team of engineers," is in the passive voice, using the future perfect tense. To change it to the active voice, the subject of the action ("a team of engineers") becomes the grammatical subject of the sentence, and the object of the action ("the intricate design") becomes the direct object. The tense (future perfect) must remain the same, which is formed with "will have" + past participle ("conceived").
