Answer 2

You were reading the novel.

to change into active or passive voice, you swap the positions of the subject and object in the sentence.

The subject in the sentence is you.

The object in the sentence is novel.

Here, novel is towards the beginning of the sentence and you is towards the end. After conversion, you will be towards the beginning of the sentence and novel will be towards the end.

We can also see that the sentence is in past continuous tense. So, we convert into active voice while maintaining the past continuous tense by changing being read to reading.
