Task: Question Answering
Input (English): Background Paragraph: Freezing is a common method of food preservation that slows both food decay and the growth of micro-organisms. Besides the effect of lower temperatures on reaction rates, freezing makes water less available for bacterial growth. 
Story: Robert, a baker, has just baked a large batch of cupcakes for his store. He won't be able to sell all of his cupcakes within the next week, so he has decided to store a portion of them in the freezer to preserve them for later. He is trying to decide if he should store the cupcakes at 0° F or at 10° F in the freezer. 
Question: If Robert initially stored the cupcakes at 0° F, but found out that increased bacterial activity could actually make the cupcakes taste better, should he raise or lower the temperature to improve the taste of the cupcakes?
Output (English): raise.
