Task: Question Generation
Input (English): Background Paragraph: When the temperature of reactants is higher, the rate of the reaction is faster. At higher temperatures, particles of reactants have more energy, so they move faster. As a result, they are more likely to bump into one another and to collide with greater force. For example, food spoils because of chemical reactions, and these reactions occur faster at higher temperatures (see the bread on the left in the Figure below ). This is why we store foods in the refrigerator or freezer (like the bread on the right in the Figure below ). The lower temperature slows the rate of spoilage. 
Story: Sam and Jim are two bakers who both just finished baking a batch of muffins. They both baked more muffins than they needed, so they decided to store some of them for later. Sam decided to store his extra muffins in the refrigerator, where the temperature is relatively high. Jim instead decided to store his extra muffins in the freezer, where the temperature is relatively low.
Output (English): Whose muffins will spoil faster?
