I gave my students this multiple choice question: Which of the following would you most likely use to study the growth of an insect over time?

Only one answer is correct among these 4 choices:
- a clock that measures seconds
- a hand lens with a large lens
- several insects that feed on other insects
- a glass aquarium with food for the insect

Could you tell me which one is correct?
