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  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  <sep> FOLLOWUP_Q: Any other suggestions?

SOLUTION: Yes

PROBLEM: CONTEXT: Ripening of the avocado is slowed down greatly by refrigeration, so it is usually a good idea to let the avocado ripen fully at room temperature. Once it is ripe, it can be stored in the refrigerator for at least a week. This way, it is ready to use whenever you want it. Fortunately, there is a day or two when the avocado is ripe, but not too ripe, so if you check on it everyday when ripening, you will be able to save it at the correct ripeness without worrying about it too much.Putting an unripened avocado in the refrigerator may prevent it from ever ripening completely. Once cooled to near freezing (40F in most refrigerators), it seems that some avocados (maybe it depends on the type) don't ripen anymore, even when removed to room temperature.  <sep>  Q: Will avocado stay fresh longer if stored in the refrigerator? A: Once it is ripe, it can be stored in the refrigerator for at least a week  <sep> FOLLOWUP_Q: Can it be opened and stored?

SOLUTION: No

PROBLEM: CONTEXT: Presumably you are experiencing rancidity, due to oxygen.While you have nitrogen flushed the bags at filling time, the bags are not impervious to oxygen diffusion.A different type of bag (an "oxygen barrier" bag material) or package (glass jar, or metal can) and, in addition, (based on other packaging I have seen) oxygen absorbing packets inside the bag may be required for long shelf life. Either alone would probably extend the shelf-life somewhat.  <sep>  Q: How do we keep our roasted cashews from smelling bad eventually? A: Presumably you are experiencing rancidity, due to oxygen  Q: So I should suck the air out of the packaging? A: A different type of bag (an "oxygen barrier" bag material) or package (glass jar, or metal can  <sep> FOLLOWUP_Q: Do you think it is just the oxygen?

SOLUTION:
Yes
