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: Fat doesn't spoil like other foods. No bacteria can live in fat. Going rancid is a chemical reaction in which the fat molecules break down. So "leaving out" is not a problem. The major factors in going rancid are light and air. The more light hits your fat, the sooner it goes rancid. Also, rancidity occurs when the fat is oxidized, meaning that if you prevent contact with air, your fat will last longer. Both factors are minimized by transferring the fat to a tightly closed opaque container. With liquid oils, you use a dark colored bottle. As bottles are impractical for solid fat, just strain your grease into a jar, close it, and put it in a cupboard. The shelf life should be many months, probably more than a year. Also, don't worry that you can get something nasty when the grease goes bad unnoticed. Rancid fat isn't a big safety risk, and ingesting it in small amounts is not problematic. If it stinks, throw it out. Before that, there is no problem eating it. The above assumes pure, well-strained fat. Pieces of fried meat left over in the fat are a safety risk, even tiny ones.  <sep>  Q: How long does grease take to go bad/rancid when sitting out? A: The shelf life should be many months, probably more than a year  Q: is that true for all types of grease? for example is it different for bacon grease versus ground beef grease? A: The above assumes pure, well-strained fat. Pieces of fried meat left over in the fat are a safety risk, even tiny ones  <sep> FOLLOWUP_Q: would it last longer or be safer if I put it in the fridge?
[A]: No


[Q]: CONTEXT: Wooden blocks are ideal for knife storage because they keep the blades dry (the wood absorbs some of the humidity in the air), preventing rusting. The motion of inserting and withdrawing blades over wood will not noticeably dull them, because you're not actually cutting the wood or indeed even applying any pressure as you do so.A good tip is to use a good quality steel to sharpen your knives with just one or two passes on each side before each use. Wash them with hot water by hand, avoiding dishwashers unless you like replacing your knives annually, then return them to the block once they're fully dried.  <sep>  Q: Does putting knives in a wooden block blade down wear out the blade? A: The motion of inserting and withdrawing blades over wood will not noticeably dull them, because you're not actually cutting the wood or indeed even applying any pressure as you do so  <sep> FOLLOWUP_Q: But I know that when I whittle, cutting the wood wears the blade of a knife down very, very quickly...I wonder why this is different?
[A]: No


[Q]: CONTEXT: Yes, nuts are very fatty, and they will eventually go rancidâ if this is the case, they will taste very poor. They can also dry out, or in more rare cases (especially if stored improperly) be infested with insects or molds.Generally, they should be good for six months to a year at their best flavor, depending on the variety (in the shell).Five years is a little long. I am not sure I would want to eat nuts that old.  <sep>  Q: Do nuts ever go bad? A: es, nuts are very fatty, and they will eventually go rancid  Q: What causes them to go rancid? A: They can also dry out, or in more rare cases (especially if stored improperly) be infested with insects or molds  Q: How would you know that they are bad? A: they will taste very poor  <sep> FOLLOWUP_Q: How long can they be stored before they go bad?
[A]:
Yes
