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 Input:
CONTEXT: They're good pretty much forever. There is not enough available water for things to grow in there. Mind you, the more aromatic and subtle parts of the flavor will dissipate over time. The sugar absorbs water, giving the combination a very low water activity, meaning there's little water available for microorganisms to use in growth. As long as your flavoring pieces are small and well mixed with sugar they will not spoil.  <sep>  Q: How long is sugar (mixed with minor ingredients) good for? A: They're good pretty much forever. There is not enough available water for things to grow in there  Q: I mixed them over a year ago, would it still be good? A: As long as your flavoring pieces are small and well mixed with sugar they will not spoil  Q: Some I mixed with lemon/orange zest, will that pose a problem? A: As long as your flavoring pieces are small and well mixed with sugar they will not spoil  <sep> FOLLOWUP_Q: Are you sure it will be safe to use?

Ex Output:
Yes

CONTEXT: Substitution in preserved foods are generally considered unsafe. Food chemistry is a complicated affair, and cooking is inherently imprecise. Sure, you can find a way to reduce the pH to that of the original recipe. But a salami is a fermented food. Your pH might be the same, but other things will change, for example the composition of the available sugars, and you can catch a different strain of bacteria. Safe preservation recipes have either been extensively tested in a lab, or used for centuries. Making a small change can destroy the delicate balance which leads to a tasty, safe food. The solution here is to look for another recipe, one which is safe but does not contain wine. For something as risky as cured meat, I'd suggest not getting some random recipe off the Internet, but choosing from a book, or maybe from the blog of a known, respectable author. This way, you get both good taste and safety, things which are hit-and-miss when making your own substitutions.  <sep>  Q: What can you substitute for wine when making homemade salami? A: The solution here is to look for another recipe, one which is safe but does not contain wine  Q: Most of the recipes I found use wine. Would citric acid work as a replacement? A: Substitution in preserved foods are generally considered unsafe  Q: So is the wine used as a preservative? A: For something as risky as cured meat, I'd suggest not getting some random recipe off the Internet, but choosing from a book, or maybe from the blog of a known, respectable author  Q: If the recipe calls for wine would a non alcoholic wine work? A: Food chemistry is a complicated affair, and cooking is inherently imprecise  <sep> FOLLOWUP_Q: Do you know of a book or a blogger that is alcohol free for me to look up some recipes for salami?

No

CONTEXT: With online meat shopping in the UK you have to go with the reputation of the source, there's no grading system which you can refer to. Top end butchers and grocery stores carry top end beef, and most of the time you do get what you pay for. Many supermarket chains have premium labels, ie Tesco Finest and Sainsbury's Taste The Difference, which are definitely much better than their regular stuff, but I think the best mainstream grocery store premium brand for meat is Coop. At the end of the day there's no substitute for getting your own eyes on the meat you are buying, so I would recommend you try local butcher shops. There's still plenty of them around in the UK, and the quality varies dramatically. There are some that will pawn off legs of lamb that are about to turn, and others which control their entire supply chain and have some of the best meat in the world. You just have to try a few and see.  <sep>  Q: As a consumer in the UK, how can I choose well marbled beef? A: Top end butchers and grocery stores carry top end beef, and most of the time you do get what you pay for  Q: Since meat is heavy, I prefer to make my purchases online, do you know of a good online source? A: With online meat shopping in the UK you have to go with the reputation of the source, there's no grading system which you can refer to  <sep> FOLLOWUP_Q: Do you suggest I buy meat from the US?
