Answer 2

The cat drank all the milk.

- "All the milk was drunk by the cat."

This is the voice changed form of the mentioned sentence in the question. Here initially the subject was 'the cat' which is changed in the second part, and the v3 form of the verb 'drink' is 'drunk' which is used in the final sentence.
