Question

A screw driver is used to unscrew the rusted nut. Give reason

Answer 1

This could be a possibility.

If the nut is otherwise inaccessible, a screw driver hammered on the side of the nut, along the direction of rotation of the thread, can help to loosen the nut and if necessary be repeated to unscrew it.
