In these passive tense questions, we are focusing on the action or object being acted upon, rather than the doer of the action. The passive voice is formed by using the appropriate form of the verb "to be" (in the correct tense) +the past participle of the main verb. This helps to shift the focus from the doer of the action to the object or the action itself. By using the passive voice, we can provide a more detailed and objective answer.
