Question

Stones feels hard . voice change

Answer 1

Answer:

Stones are hardly felt.

Answer 2

answer-

in english language we study the chapter of active passive in most cases where we do the voice change by replacing the subject with the object and the vice versa

but there is another short part to it which is known as the-

quasi passive

we apply it on the sentences like this with no object at all

the voice change here is-

the stone is hard when felt

have a nice day
