Given a paragraph about cooking, and a set of conversational question answers about the paragraph, answer a follow-up question from the paragraph. The paragraph has a prefix 'CONTEXT:'. Each conversation question has a prefix 'Q:' followed by answer prefix 'A:'. The final followup question has a prefix 'FOLLOWUP_Q:'.

Input: Consider Input: 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  <sep> FOLLOWUP_Q: What if it doesn't have any odor?

Output: Even if you don't smell anything obvious, it could still be subtly rancid


Input: Consider Input: CONTEXT: Basically, you can refreeze the raspberries.When a fruit or veg. is frozen, the water inside the plant cell expands, and bursts the cell wall, which is why there is so much 'juice' when you thaw. If you refreeze, you can be sure that the raspberries will freeze into a giant block. If you are using them to make a sauce or a jam, this is not significant. That being said, if you are using frozen raspberries in the first place, you are obviously not looking for a perfectly intact raspberry, you are using them for some other purpose. Therefor, refreezing is no big deal. I recently answered another question about freezing and refreezing, and how it is basically a myth that it renders the refrozen product inedible. Any time you freeze you know that you are not going to get 'exactly' the same product when you thaw it, and the same goes with refreezing, there is always a 'slight' degredation of the product with each successive freeze (do you like my liberal usage of quotes?) You won't poison yourself or anything like that, you should have no worries.That being said, what are you doing with the berries? Certainly a refrozen raspberry should be no worse that a raspberry frozen once.  <sep>  Q: Can I re-freeze fruit? A: f you refreeze, you can be sure that the raspberries will freeze into a giant block  Q: I had let them thaw but have put them in the fridge since I realised my mistake. Am I able to refreeze the berries or should I find some immediate use for them? A: refreezing is no big deal  <sep> FOLLOWUP_Q: What are the risks / consequences if I do refreeze?

Output: there is always a 'slight' degredation of the product with each successive freeze


Input: Consider Input: CONTEXT: Propane and butane are pure alkanes. They don't produce anything nasty when burned. The worst you could possibly get should be carbon monoxide (and I am not even sure it can be produced in a torch, the dioxide ifs much more likely), but it being a gas, it won't stick to your food. The complex molecules you get from heating the food itself have more potential for being harmful than the combustion products of a propane butane torch. Ago yes, it is food safe. Another matter of safety is that it is easier to cause a fire with a hardware store torch, because it has more power than the kitchen ones. But a sensible adult should be able to handle the thing safely.  <sep>  Q: Is it safe to use a propane torch bought at a Hardware store? A: a sensible adult should be able to handle the thing safely  Q: Is there something different about the torches and/or fuel that is sold at a culinary store? A: Propane and butane are pure alkanes  <sep> FOLLOWUP_Q: Are there any precautions I should take when using it for culinary type stuff?


Output: The worst you could possibly get should be carbon monoxide (and I am not even sure it can be produced in a torch, the dioxide ifs much more likely), but it being a gas, it won't stick to your food
