Correct! A screw can be inserted with less force than a nail because it has threads that help it grip and twist into the material, while a nail requires more force to be pounded in.

Answer 2

[AI-generated answer — Step-by-Step Bot]

The correct answer is D. A screw allows the force to be applied in a more convenient direction. By rotating the screw, it can be easily inserted and tightened, providing a secure fastening. With a nail, the force can only be applied in a straight line, which may not always be convenient or effective.
