You will be given a definition of a task first, then some input of the task.
Given a paragraph about cooking, and a set of conversational question answers about the paragraph, generate a relevant question to the topic of the paragraph. The paragraph has the prefix 'CONTEXT:'. Each conversation question has a prefix `Q:` followed by the answer prefix `A:`.

CONTEXT: If a lid doesn't have a vent and the pot does not have any sort of locking mechanism like a pressure cooker, then the pressure of the steam inside will lift the lid off the pot and steam will escape. That was the "dancing" of the lid that you experienced. Venting holes in a lid just let some steam escape so the lid doesn't bang around, having a vent hole or not wouldn't make your idli's sticky.  <sep>  Q: Must a lid for a pot used for steaming be vented? A: If a lid doesn't have a vent and the pot does not have any sort of locking mechanism like a pressure cooker, then the pressure of the steam inside will lift the lid off the pot and steam will escape 
Output:
I have a lid that fits the Instant Pot exactly, but it lacks the steam release vent. How much does this matter?
