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:`.

Input: Consider 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 chocolate and pear cake whose batter is made with yolks, sugar, butter, melted chocolate and amaretti, flour and baking powder and whisked whites. It was (not very evenly) divided in two layers, sandwiching a layer of pear pieces pre-cooked in rum.### My question is: what are the holes due to? A: 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  Q: Uneven division of batter? A: 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  Q: How can this be prevented A: folding the whites very gently, and generally erring on the side of too little whisking  Q: Any other suggestions? A: there are no pear pieces, my second guess is badly dissolved flour  <sep> FOLLOWUP_Q: Could using a better source of flour work?

Output: No


Input: Consider Input: CONTEXT: In the US, I normally see them marketed as "heirloom" tomatoes; I don't know if there are specific regulations in the UK or Finland that might have restrictions on the term's use. (like there now is in the US with "organic" )Because they weren't developed for industrialized farming, they didn't focus on breeding in traits that were desired for mass production -- size, round shape, bright color, shelf life, durability in transport.As such, there's a much wider variety, and they tend to be locally grown on small farms (as they don't tend to transport well, or be suitable for mechanized production). They might've been bred for sweetness, tartness, number of fruit per plant, disease resistance, etc, so you can't say that heirlooms necessarily taste better; a locally grown, picked that day non-heirloom tomato might taste just as good.To make this clear -- very few vegetables are produced in a truly 'uncontrolled' environment (maybe 'less controlled' environment)-- humans have been selecting for specific traits for centuries; it's just that the processes used were much less high-tech back then -- you saved the seeds from plants that produced what you liked, it's possible that some might've even been hand-pollinated to cross breed cultivars.)  <sep>  Q: What makes a tomato "heirloom"? A: They might've been bred for sweetness, tartness, number of fruit per plant, disease resistance  Q: What is the difference between heirloom and conventional tomatoes? A: they weren't developed for industrialized farming, they didn't focus on breeding in traits that were desired for mass production  <sep> FOLLOWUP_Q: Is heirloom the same as heritage?

Output: No


Input: Consider Input: CONTEXT: I'm going with an electric slicer. The item I envisioned does not exist.Update: The housemates are happy now. They're computer geeks and love gadgets. They can now slice up their own ham and turkey to their hearts' content.The slicer takes up space, but will pay for itself in a few months. We were getting deli slices for $8 - $10 per pound. Now I can get frozen turkey breast for ~ $3 - $4 per pound, roast, slice, and freeze the excess for future weeks. ;~)  <sep>  Q: Is there a manual meat slicer that can help with thin even slices?


Output: No
