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: CONTEXT: Duck feet will render plenty of gelatin because of the amount of cartilage, same as chicken feet. Any bird's feet are a good choice.The method for making stock is pretty much the same no matter what you put into it, so yes, you can follow your favourite recipe for chicken stock and substitute duck feet. The only thing to keep in mind is that duck feet, like any other duck parts, are substantially more fatty than their chicken equivalents, so assuming you want a clear or mostly-clear stock, you'll have to spend a lot of time skimming.Alternatively you can clean the feet and other bones by boiling them in plain water for 5-10 minutes, then dumping it all out and starting over - which is what your linked recipe suggests. I don't usually do this for brown stocks because you lose a lot of flavour, but if you're starting from raw then it won't make much difference and it's an easy/lazy way to get rid of a lot of the fat at once. <sep> Q: Can I use duck feet to make duck stock A: The method for making stock is pretty much the same no matter what you put into it, so yes, you can follow your favourite recipe for chicken stock and substitute duck feet Q: Does it add the same flavor and mouth feel? A: The only thing to keep in mind is that duck feet, like any other duck parts, are substantially more fatty than their chicken equivalents <sep> FOLLOWUP_Q: How does this change things?
Example solution: Yes
Example explanation: The question asks about how the stock can be less fatty or mostly clear. This can be infered from the previous conversation. The answer is written in the passage that if mostly clear stock is needed then one has spend a lot of time skimming.

Problem: CONTEXT: This should be no problem. It is basically the same process as making a vinaigrette, only using water instead of vinegar, and lecithin instead of mustard. Here's how I would go about it. Let's say you have 1 cup of oil to emulsify. Go buy soy lecithin at a health food store. Take 1/2 cup of water, and dissolve 1 teaspoon of the soy lecithin in it. Use a blender or immersion blender. With the blender running, slowly drizzle in the cod liver oil. It will emulsify - the oil will disperse into ultra-fine droplets in the water, and presumably the taste will be both diluted and somewhat hidden by being locked up in little droplets. If this doesn't work, you just need more lecithin, so dissolve a bit more in another 1/4 cup of water and drizzle the whole thing back in to the blender.Naturally you'll want to take 50% more, since the oil is now only 2/3 of the volume.Those other ingredients are for flavor and anti-oxidation, not needed for the basic thing you are trying to accomplish. <sep> Q: How can I emulsify cod liver oil, or otherwise mask its taste?
Solution: Yes
