Question

Identify the sentence using active voice the car be washed by Dave

Answer 1

I believe the correct answer would be:
Dave washed the car. Because Dave is the one who is doing the action, not the car

Hope this helps

Answer 2

Dave will wash the car.

Step-by-step explanation:

The above sentence "The car be washed by Dave" will be changed into "Dave will wash the car".

When sentences are changed from the passive voice to active voice, the subject of the sentence in the passive voice, in this case Dave, will be at the start of the sentence. In order to identify who the subject of the sentence is, the 'who or what' doing the action in the sentence, most often following the "by the' word, is the subject. And accordingly, the verb will be changed to make the sentence into the active voice.
