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:`.

[EX 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?
[EX A]: No

[EX Q]: CONTEXT: The word you want for research purposes is raitha - there are lots of ideas about how to make raitha.If you want a garlic flavour, the lazy way is to use the garlic paste you can buy in jars. The paste is ground so fine it will avoid the texture problems without any effort.The commonest flavours are mint or chilli, sometimes both together. Those get served with chopped onion, cucumber and tomato - or with papadoms/pappads.I find the most popular dipping versions result from the inclusion of a little mango chutney, Major Grey is good because it has ginger, too.  <sep>  Q: My yogurt turned out clumpy what went wrong?
[EX A]: No

[EX Q]: CONTEXT: Overly sour yogurt is a sign of inconsistent inoculationCheck the type of culture you are using, and ensure you are keeping the yogurt above 37C for more than six hours. The yogurt should finish as a solid lump that resists pouring, not a thick liquid, or a lumpy pastePouring off the whey and straining the yogurt makes it more creamy and taste sweeterThickeners are not required, just complete inoculationFor sweet yogurt dishes I mostly use sour berries (blackberry, raspberry etc) so it is expected to be somewhat sour anyway  <sep>  Q: How to reduce the natural sourness of homemade frozen yogurt? A: Pouring off the whey and straining the yogurt makes it more creamy and taste sweeter  Q: Do I need to cook it to separate the whey out or just leave it to drain for a certain amount of time? A: Check the type of culture you are using, and ensure you are keeping the yogurt above 37C for more than six hours  <sep> FOLLOWUP_Q: After I keep it at that temperature for long enough it will be less sour but will it still freeze solid enough like commercial frozen yogurts?
[EX A]:
No
