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:`.

CONTEXT: There's always the delight of botulism, which thrives in the anaerobic environment provided by vacuum packing. Listeria and vibrio bacteria can grow in an anaerobic environment, and are potential food safety risks present in fish. With this in mind, I would not expect vacuum packing to extend the life of a fish much. It will reduce freezer burn though!  <sep>  Q: Do you think it makes a difference what type of fish it is? A: Listeria and vibrio bacteria can grow in an anaerobic environment, and are potential food safety risks present in fish  <sep> FOLLOWUP_Q: Is the vacuum seal an anaerobic environment?
Yes

CONTEXT: Just an idea... I've had problems making foam because of hard/basic tap water (a lot of chalk in the water) - making frape though, not garlic foam:) Foam will more easily form in soft water as you can easily test with a piece of soap. If you have hard tap water you could try using boiled water (some of the chalk in the water will react and leave a residue on the bottom of the pot) or bottled water with pH 7 (neutral). Another idea would be to add just enough acid for neutralisation but I imagine that could be a bit tricky and you'd risk the milk curdling so I wouldn't recommend it.  <sep>  Q: This is my first time making a foam using soy lecithin but I want to know why there was not enough foam? A: Just an idea... I've had problems making foam because of hard/basic tap water (a lot of chalk in the water  <sep> FOLLOWUP_Q: I put the foam I did get from my first try in the fridge. Is there any way to salvage this?
No

CONTEXT: Most turkeys sold in the United States for Thanksgiving are frozen. It simply is not feasible for meat processors to process the huge spike in turkeys for the holiday and provide everyone a fresh turkey. Expect to pay a premium for a fresh turkey over a frozen one. If you buy a frozen turkey, from a quality standpoint it does not matter whether you buy a turkey a month out from Thanksgiving (now) or wait to buy the turkey later. You will basically get the same product.  <sep>  Q: When's the best time to buy a Thanksgiving turkey? A: If you buy a frozen turkey, from a quality standpoint it does not matter whether you buy a turkey a month out from Thanksgiving (now) or wait to buy the turkey later  <sep> FOLLOWUP_Q: So it's okay to buy a Thanksgiving turkey early?

Yes
