I gave my students this multiple choice question: When a baker bakes bread, he prepares the dough by mixing 2 cups of flour with 1 cup of water. The water needs to be 85°F. Which tools are best for the baker to measure both the volume and temperature of the water?

Only one answer is correct among these 4 choices:
- a balance and a ruler
- a balance and a thermometer
- a measuring cup and a balance
- a measuring cup and a thermometer

Could you tell me which one is correct?
