Correct Answer

Option D — Why were the substantial stylistic anomalies overlooked by the editor?

Detailed Solution & Explanation

The correct answer is Why were the substantial stylistic anomalies overlooked by the editor?

Key Points

• The active sentence is in the simple past ("did … overlook"), so the passive must also be simple past: was/were + past participle.
• The subject of the passive is *anomalies*, which is plural, giving were overlooked.
• The question word Why stays at the front, and the original subject (*the editor*) becomes the agent introduced by by.
• The distractors shift the tense: option A uses the present perfect (*have been*), option B the present continuous (*are being*), and option C is ungrammatical (*did … be overlooked*).
• Keep the tense unchanged when converting voice — only the verb form and the positions of subject and object move.

Additional Information

• Passive voice: object + appropriate form of "be" + past participle + by + agent, with the tense preserved from the active sentence.
• Tense forms: present simple *is/are done*, past simple *was/were done*, present perfect *has/have been done*, future *will be done*, and modals *can/must be done*.
• In questions, the question word stays in front and the auxiliary agrees with the new subject; imperatives become *Let … be …*.
