Given a paragraph about cooking, and a set of conversational questions and answers about the paragraph, say whether the passage contains sufficient information to answer the follow-up question. Say Yes if it is answerable; otherwise, say No. The paragraph has the prefix 'CONTEXT:'. Each conversation question has a prefix `Q:` followed by the answer prefix `A:`, and the follow-up question has a prefix `FOLLOWUP_Q:`.

Q: CONTEXT: Yes, it can go bad.It's pretty much the same as the way flour can go bad: the fats can go rancid. Grains are mostly starch, but they contain enough fat for rancidity to be a noticeable problem. There's a huge amount of variability in how long that takes, though. If it's airtight and kept in a cool, dark place, it'll last much longer than the best before date. But if it's been exposed to air, light, or heat, it can go pretty fast, perhaps even before the best before date.So, smell it. If you detect any unpleasant smells, you probably don't want to eat it. Even if you don't smell anything obvious, it could still be subtly rancid, so if you're planning on serving it to anyone, you might want to cook a small bit to test.  <sep>  Q: Does polenta go off'? A: it can go bad  Q: How can I tell if it's bad? A: smell it. If you detect any unpleasant smells, you probably don't want to eat it  Q: What if it doesn't have any odor? A: Even if you don't smell anything obvious, it could still be subtly rancid  Q: Do you think I should just throw the box away says the best before date has long perished? A: If it's airtight and kept in a cool, dark place, it'll last much longer than the best before date  <sep> FOLLOWUP_Q: Do you know what the average shelf life is for polenta by any chance?

A: No

Q: CONTEXT: If you whisk egg whites to much they will definitely separate.Basically you are over tightening their stretchy proteins which squeeze out all the water. You are left with useless protein fluff floating on water.The flavor and odor will not change, however. That would be a sign off spoiling and unrelated to the whisking.  <sep>  Q: Is it possible to whisk egg whites too much? A: If you whisk egg whites to much they will definitely separate  Q: What happens to rhetoric If the egg whites separate?###The food not rhetoric A: Basically you are over tightening their stretchy proteins which squeeze out all the water  Q: Would this make the food more dry? A: You are left with useless protein fluff floating on water  <sep> FOLLOWUP_Q: If you whisk egg whites too much should you throw them away and start over?

A: No

Q: CONTEXT: You are better off making the crumpets in advance and then reheating them. The rising agent in crumpets is usually bicarbonate of soda or baking powder, and so the batter can't be 'held' in the fridge like a yeasted batter - it would be very dense if you left it too long.So, make the crumpets, then reheat them. I'd suggest using the toaster - this is how crumpets are sold and prepared in the UK. Make sure you have plenty of salted butter on hand too!  <sep>  Q: Can I make crumpet batter in advance? A: You are better off making the crumpets in advance and then reheating them  Q: How long do I reheat them? A: I'd suggest using the toaster - this is how crumpets are sold and prepared in the UK  <sep> FOLLOWUP_Q: In a toaster? I thought they could be made in a pan as well?

A:
No
