premise: How to store leftover pasta<br>Place the cooked pasta in an airtight container. The container you use should have a lid or other type of secure closure to keep air from getting in. When exposed to air, the moisture in cooked pasta can become a breeding ground for bacteria and mold.
hypothesis: Place the cooked pasta in an airtight container and store it at room temperature.
reason: The text does not mention what temperature to store it at; the model just assumed room temp was unsafe.
