Answer :
Among the options, the one that contains a sentence expressed in the active voice is:
D. Twentieth-century poets have written many famous poems.
- In the active voice, the subject of the sentence is the performer of the action expressed by the verb.
- The verb's object is the receiver of that action.
- For example: I cut the tree.
- In the passive voice, the subject of the sentence is NOT the performer of the action. It is the receiver.
- The performer of the action is the agent of the sentence, which appears after the preposition "by". In some cases, the agent can be omitted.
- For example: The tree was but (by me).
- With that in mind, we can choose letter D as the one in the active voice. The ones performing the action of writing are the poets.
- The poem is the one receiving the action. Therefore, sentence A, B, and C are all in the passive voice.
