Question

Explanation:

The question asks for the difference between two bolts. The first option compares the fineness of threads, the second compares thread - lengths and the third compares tensile strengths.

Answer:

The thread of the bolt on the left is finer than the bolt on the right.
The thread length of the bolt on the left is longer than the bolt on the right.
The tensile strength of the bolt on the left is greater than the bolt on the right.
