Answer:
Do you know we make cheese from milk?
Explanation:
The sentence in passive voice is: "Do you know cheese is made from milk."
The sentence, in the passive, is stating a fact, and the subject is implicit. If we write it in the active voice where we use "we" as a subject, the meaning and the context of the sentence changes, so we can also replace the subject with "industries" or "farmers" to make the sentences in the active and passive have a similar meaning, which is stating a fact.
When we write the sentence in the active the verb goes in the present tense, and there is no auxiliary verb. Besides, the subject is explicit at the beginning of the sentence before the verb. In passive voice, the direct object, which is cheese, moves to the subject's position, and the verb goes in past tense with the auxiliary in the present tense.
