Teacher: 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:'.
Teacher: Now, understand the problem? If you are still confused, see the following 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?
Solution: Yes
Reason: 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.

Now, solve this instance: CONTEXT: There's no particular reason you couldn't prepare a stock with something other than water, but it's the equivalent of buying a ream of heavy pink paper, rather than plain white photocopy paper. If that's the effect you really want, great. The thing is, stock is meant to be as boring as plain white photocopy paper -- it is a foundation for other things, versatile and effective, subtly enhancing without overwhelming the dish. For your beer idea, for example, I would cook down a couple bottles and add some stock to it. That way, the rest of my batch of stock would be useful for other recipes that don't use beer.Note that stock may be boring but shouldn't be flavorless; stock still should taste good. If your stock was flavorless, try upping the amount of meat, veggies, and herbs compared to bones. Also, bear in mind that stock should not contain salt (you will likely reduce the stock at some point). The lack of salt, however, will deaden the flavor. When you are ready to use the stock, be sure to add a pinch of salt. <sep> Q: Can I use other liquid than water when making stock?

Yes
