Information and Ideas practice question

A council claims that its free bus pass for under-18s has increased young people's use of the town's library.

Which finding, if true, would most directly support the claim?

  1. A. Since the pass was introduced, library visits by under-18s have risen by 30 percent, while visits by adults have not changed.Correct
  2. B. The library has extended its opening hours.
  3. C. More buses now stop outside the library.
  4. D. The number of under-18s in the town has fallen.

Answer: A. Since the pass was introduced, library visits by under-18s have risen by 30 percent, while visits by adults have not changed.

A rise among the group given the pass, and none among others.

Why the other answers are wrong

B. The library has extended its opening hours.
Longer hours would be a rival explanation, not support.
C. More buses now stop outside the library.
More buses would be a rival explanation.
D. The number of under-18s in the town has fallen.
Fewer young people would make a rise harder to explain, not easier.
