Question

Which advantage does a screw have over a nail A a screw is able to reduce the total amount of work needed B a screw allows the force to be applied in a more convenient direction C a screw is pushed through a shorter distance D a screw could be inserted with less force than a nail

Answer 1

The correct advantage of a screw over a nail is:

**D: a screw could be inserted with less force than a nail.**

Screws have threads that grip the material they are being driven into, which allows them to hold more securely with less force compared to nails that rely mostly on friction and material deformation to stay in place.
