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:`.

Example Input: CONTEXT: There is not really a turning point. The way that wine goes bad is the process of making vinegar. From wikipedia:The word "vinegar" derives from the Old French vin aigre, meaning "sour wine".The Canadian government limits things that can be sold as 'vinegar' to something with an acetic acid content of 4-12%, so you could do the technical-bureaucratic thing and wait for the acetic acid to get up to 4%.If you aren't hung up on technicalities, then you can use it as soon as it gets sour enough. It is done when all the alcohol has been changed to acetic acid, but it is a bit hard to taste since the acetic flavor dominates.  <sep>  Q: When is homemade wine-based vinegar simply bad wine? A: There is not really a turning point. The way that wine goes bad is the process of making vinegar  <sep> FOLLOWUP_Q: Does heat have anything to do with the shelf life?
Example Output: No

Example Input: CONTEXT: I have seen this happening more than once. While I don't know the whole theory behind it, each time it happened, there was something just below the hole, let's call it "the lump". What I think happens is that the lump is too heavy. When the batter below it tries to rise, it doesn't have the strength to push up the lump. This could be combined with differences in heat transfer throughout the batter vs. on the batter-lump transition in preventing rising (I am certain they exist, but I don't know whether they have an effect at all). The result is a hole where the batter didn't rise, surrounded by nicely risen batter. As to where the lump comes from: you say "chocolate and pear cake". If you have pear pieces in the batter, right under the surface, they can do this. I have certainly seen it happen when the recipe includes fruit pieces in the batter. If there are no pear pieces, my second guess is badly dissolved flour. The directions for this type of cake normally include folding the whites very gently, and generally erring on the side of too little whisking. This could contribute to uneven batter texture, resulting in lumps. In the second case, the cake may have some less-than-pleasant pieces, but will still be mostly good. If it is fruit, the holes are purely a cosmetic problem. So not much harm done either way, unless you are shooting for a prize at a baking competition.  <sep>  Q: I baked a cake and it has holes in it why? A: each time it happened, there was something just below the hole, let's call it "the lump  Q: Was it because the batter was uneven? A: What I think happens is that the lump is too heavy  Q: Could it be uneven rising? A: When the batter below it tries to rise, it doesn't have the strength to push up the lump  Q: How could this be prevented? A: folding the whites very gently, and generally erring on the side of too little whisking  Q: Anything else? A: my second guess is badly dissolved flour  <sep> FOLLOWUP_Q: How long should I bake it?
Example Output: No

Example Input: CONTEXT: Transfer of heat. First you need a hot pan (sprinkle some drops of water on the pan, it should sizzle). Then you add a drop of oil and swirl it around. When the oil forms a striated pattern, it's hot. Then you put the meat in.The hot oil helps to transfer heat from the bottom of the pan to the meat. You only need a spoonful of oil.  <sep>  Q: Why do people put oil/butter in pan when frying ground beef? A: Transfer of heat. First you need a hot pan  Q: But doesn't the fat from the beef do that? A: The hot oil helps to transfer heat from the bottom of the pan to the meat. You only need a spoonful of oil  Q: oh I see, how much butter would you need? A: you add a drop of oil and swirl it around  <sep> FOLLOWUP_Q: it's okay, do you think it would add flavor to the beef using butter?
Example Output:
No
