Change the following passive voices to correct active voices by choosi...
To change the passive voice sentence "The boxes have not been unwrapped yet" to an active voice sentence, we need to identify the subject and the correct verb form.
The subject of the sentence is "the boxes," and the verb is "unwrapped."
The correct active voice options are:
A:
No one has unwrapped the boxes yet.
- This option correctly identifies the subject as "no one" and uses the active verb form "unwrapped."
B:
They have not unwrapped the boxes yet.
- This option uses the pronoun "they" as the subject and the active verb form "unwrapped."
C:
The boxes have not unwrapped them yet.
- This option is incorrect as it suggests that the boxes are doing the action of unwrapping themselves.
D:
Option a or b.
- This option correctly identifies both A and B as valid active voice sentences.
Therefore, the correct answer is D: Option a or b.
