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:`.

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?
No

CONTEXT: To prevent the sticking, you might want to use a spray oil, maybe even just on the foil before you put the vegetables and potatoes on. It's a tiny amount of oil, not enough to make things noticeably greasy, but will be pretty effective. Another spray over the top will make them brown a little more nicely and may even prevent a little drying out. Alternatively, you can just toss them all in a bowl with a small amount of oil; it really doesn't take much, and I'd hardly describe it as "covering with a lot of oil."As for preventing things from drying out, first and foremost, don't overcook them. Broccoli and onions both roast very nicely, but you definitely want to pull it out before it starts browning/burning too much. If you slice the potatoes thinly enough, they'll cook in roughly the same amount of time as the broccoli and onions. So if things are getting overcooked, just don't leave them in the oven as long.You can also always try covering them. Another sheet of foil over the top will trap a fair amount of moisture, letting them steam a bit and probably preventing some burning as well.(I suppose it's also possible that it's all drying out because you're cooking them too slowly, so they have plenty of time for moisture to escape, but that seems less likely given the way you described things.)  <sep>  Q: When I cook my meat, I usually bake or broil it, I basically use the oven. I like using the oven to make the side dish while baking the meat. Usually the side dish consists of a combination of sweet potatoes / yams, broccoli and onions. I slice the potatoes and make sure the broccoli pieces and onions are large enough so they will not overcook / burn. However, usually this combination ends up being really dry, and everything sticks to the aluminum foil. ###So im looking to bake side dishes, having problems with dryness A: To prevent the sticking, you might want to use a spray oil, maybe even just on the foil before you put the vegetables and potatoes on  Q: what kind of oil is best? A: Another spray over the top will make them brown a little more nicely and may even prevent a little drying out  <sep> FOLLOWUP_Q: Yes, but which oil is best to be used? I want my meals to be healthy, and covering everything with alot of oil is not appealing to me.
No

CONTEXT: Leaving any sort of sugar confection in the fridge (as it will out of the fridge also, but to a lesser extent) will soften the sugar after a prolonged period due to the moisture in the air. However, putting it in the fridge for a short period of time will simply speed up the cooling process as you put in your question.  <sep>  Q: Can I cool my toffee in the fridge? A: Leaving any sort of sugar confection in the fridge (as it will out of the fridge also, but to a lesser extent) will soften the sugar after a prolonged period due to the moisture in the air  <sep> FOLLOWUP_Q: Is there anything I should look out for or take care of before I put it in the fridge ?

No
