TASK DEFINITION: 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:`.
PROBLEM: 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  <sep> FOLLOWUP_Q: Uneven division of batter?

SOLUTION: Yes

PROBLEM: CONTEXT: Chocolate is an odd substance when it comes to melting and hardening. When chocolate hardens, its melting point will end up being just a few degrees higher than the hardening temperature.When chocolate crystallizes at high temperatures, it forms a strong, dense crystalline structure that, texture-wise, is quite brittle. Most bought chocolate (baker's chocolate and chips) is already tempered, but when you melt it, you break down that crystalline structure, and if you harden it at room temperature then it ends up forming very weak crystals that will melt in your hand.If you use a special coating chocolate (couverture or the lower-quality compound chocolate) then you don't need to worry so much about tempering (although it's still a good idea), but if you use ordinary chocolate and don't temper it then your coating will end up being messy and wet and rub off on your hands while you eat it. It might even melt while stored.Tempering is the key to making a room-temperature-stable chocolate coating. If you don't do this, you'll need to keep your pastries refrigerated until they're ready to consume.  <sep>  Q: What is the purpose of tempering chocolate? A: Tempering is the key to making a room-temperature-stable chocolate coating  <sep> FOLLOWUP_Q: How do you temper chocolate?

SOLUTION: No

PROBLEM: CONTEXT: Apparently the chicken haddie plant had fire damage and we have not been able to buy it for over a year now in New Brunswick, Canada. I too grew up with it for making the best fish cakes. Anyway, the plant is up and running again as of January 2012 and I've been buying at Sobeys.  <sep>  Q: Are chicken haddies still available? A: the plant is up and running again as of January 2012  Q: Where exactly is it located? A: New Brunswick, Canada  Q: Do you know exactly what companie?###companies*? A: I've been buying at Sobeys  Q: Do you get good ones over there? A: I too grew up with it for making the best fish cakes  <sep> FOLLOWUP_Q: Have you ever tried its chowder?

SOLUTION:
Yes
