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: A scientist is observing two chemicals react. The reaction is very slow and he wants to find a way to speed up the reaction. One day the labs air conditioner breaks, increasing the heat, in the lab and he notices the reaction is happening significantly faster than usual.
Output (English): Will the chemicals the scientist used react faster or slower if you decrease the temperature?
