compare the sizes of the students compare the ages of the students compare the distances that the ball rolled compare the number of times the ball was rolled
I gave my students this multiple choice question: Four different students take turns pushing a large, heavy ball on the school parking lot. What is the best way to determine which student used the most force to push the ball?

Only one answer is correct among these 4 choices:
- compare the sizes of the students
- compare the ages of the students
- compare the distances that the ball rolled
- compare the number of times the ball was rolled

Could you tell me which one is correct?

compare the distances that the ball rolled
