Answer 1

Answer:

Patients were being attended by some doctors.

Explanation: In the above-given sentence, the question which is in past continuous tense inactive form is asked to change into a passive form which reminds us of the formula or the structure of the sentence which is subject + was or were + being + past participle, where the word being is always present in a continuous passive no matter what the verb tense is.
