I have to change the voice of the following sentence

Our mothers use tongs while making chapaties.

I think its answer would be

Tongs are used by our mothers while chapaties are being made.

But the answer in my book is

Tongs are used by our mothers while making chapaties.

Which one is correct?

1 Answer 1


Both are correct, but I think the book's version is preferable simply because it's more concise and less clunky.

This ngram makes it pretty clear which version you'd be more likely to encounter in published books.
