Information and Ideas practice question
None of the harbour's rope-makers can explain how they judge when a strand is twisted enough; they say they feel it in the wrist. An engineer who measured them found that each stopped within two percent of the same tension, every time, without ever having seen a number.
Which choice best states the main idea of the text?
- A. The rope-makers' unexplained skill is in fact remarkably precise and consistent.Correct
- B. The rope-makers use instruments to measure tension.
- C. The rope-makers' work varies widely in quality.
- D. The engineer taught the rope-makers to twist rope.

Why the other answers are wrong
- B. The rope-makers use instruments to measure tension.

- C. The rope-makers' work varies widely in quality.
- Within two percent every time is the opposite of wide variation.
