Information and Ideas practice question
Two bakeries last week:
Bakery M: 4 staff, 2,000 loaves
Bakery N: 3 staff, 1,800 loaves
A journalist claims that Bakery N's staff each baked more loaves than Bakery M's. Which choice most effectively uses data from the table to support the claim?
- A. Bakery N's staff baked 600 loaves each (1,800 ÷ 3), compared with 500 each at Bakery M (2,000 ÷ 4).Correct
- B. Bakery M baked more loaves than Bakery N.
- C. Bakery N has fewer staff than Bakery M.
- D. Bakery N baked 1,800 loaves.
Answer: A. Bakery N's staff baked 600 loaves each (1,800 ÷ 3), compared with 500 each at Bakery M (2,000 ÷ 4).
Per person requires dividing loaves by staff for both bakeries.
Why the other answers are wrong
- B. Bakery M baked more loaves than Bakery N.
- Totals point the wrong way and ignore staff numbers.
- C. Bakery N has fewer staff than Bakery M.
- Staff count alone says nothing about loaves per person.
- D. Bakery N baked 1,800 loaves.
- A total without a rate.
