Information and Ideas practice question

Two libraries last year: Library P: 5,000 members, 60,000 loans Library Q: 2,000 members, 30,000 loans

A librarian claims that Library Q's members borrow more books each than Library P's. Which choice most effectively uses data from the table to support the claim?

  1. A. Library Q's members borrowed 15 books each (30,000 ÷ 2,000), compared with 12 each at Library P (60,000 ÷ 5,000).Correct
  2. B. Library P had more loans than Library Q.
  3. C. Library Q has fewer members than Library P.
  4. D. Library Q had 30,000 loans.

Answer: A. Library Q's members borrowed 15 books each (30,000 ÷ 2,000), compared with 12 each at Library P (60,000 ÷ 5,000).

Per member requires dividing loans by members for both libraries.

Why the other answers are wrong

B. Library P had more loans than Library Q.
Totals point the wrong way and ignore membership.
C. Library Q has fewer members than Library P.
Membership alone says nothing about loans per member.
D. Library Q had 30,000 loans.
A total without a rate.
