I gave my students this multiple choice question: Students measured how long it took for an ice cube to melt. Which measurement best represents how long it took for the ice cube to melt?

Only one answer is correct among these 4 choices:
- 20° Celsius
- 40 grams
- 60 milliliters
- 80 seconds

Could you tell me which one is correct?
