Answer 2

Answer:

The mural was painted by some artist last year.

Explanation:

When it comes to active sentences, you have your subject, your verb, and your direct object. However, when you want to make a passive sentence, you should place the direct object in the initial position (acting as something similar to a subject) to place emphasis on that particular word.

So, in the active sentence, the subject was some artist, the verb was painted, and the object was the mural. In order to make the sentence passive, we place The mural first, and then denote whom the action was made by (in this case, some artist). The tense should be the same in both sentences - past simple in the active sentence, and past simple passive in the passive one.
