Given a paragraph about cooking, and a set of conversational question answers about the paragraph, generate a relevant question to the topic of the paragraph. The paragraph has the prefix 'CONTEXT:'. Each conversation question has a prefix `Q:` followed by the answer prefix `A:`.

[Q]: CONTEXT: I'm afraid you interpret the tables wrong. You aren't destroying calories, you are adding water (=0 cal) to the dry rice. As the rice absorbs the water, you are in fact measuring rice + water for cooked rice.This is true for calorie tables that measure by volume (like here) and by weight.If you are cooking your rice by boiling and straining, you are effectively losing a few calories due to the starch that gets drained with the water, but that's not what you asked here.  <sep>  Q: How to maintain the calories in rice (which were present in it in its raw form) after cooking it? A: You aren't destroying calories, you are adding water (=0 cal) to the dry rice  Q: So to maintain the same calories I just don't drain the water? A: the rice absorbs the water 
[A]: Is there a difference in the calories or say white rice compared to brown rice ?


[Q]: CONTEXT: Yes, it can go bad.It's pretty much the same as the way flour can go bad: the fats can go rancid. Grains are mostly starch, but they contain enough fat for rancidity to be a noticeable problem. There's a huge amount of variability in how long that takes, though. If it's airtight and kept in a cool, dark place, it'll last much longer than the best before date. But if it's been exposed to air, light, or heat, it can go pretty fast, perhaps even before the best before date.So, smell it. If you detect any unpleasant smells, you probably don't want to eat it. Even if you don't smell anything obvious, it could still be subtly rancid, so if you're planning on serving it to anyone, you might want to cook a small bit to test.  <sep>  Q: Does polenta 'go off'? A: it can go bad  Q: What is an indication that it goes bad? A: If you detect any unpleasant smells, you probably don't want to eat it. Even if you don't smell anything obvious, it could still be subtly rancid  Q: Does the taste change when it goes bad? A: Grains are mostly starch, but they contain enough fat for rancidity to be a noticeable problem 
[A]: What else changes when it goes off?


[Q]: CONTEXT: A number of Chinese restaurants are happy to prepare it without pork or beef. I've seen it with pork (most common) or beef (sometimes).A vegetarian Chinese place that I occasionally visit uses a "vegetarian ham" along with some vegetables like peas to augment the custardy texture of the soft tofu. I like to add some ja tsai (zasai, depending on romanization preferences) pickles in there, though I'd guess that's not that common.Pork is not absolutely essential to the identity of the dish, but it's certainly the most likely version to be served.  <sep>  Q: What do you know about Ma Po Doufu? A: A number of Chinese restaurants are happy to prepare it without pork or beef. I've seen it with pork (most common) or beef (sometimes 
[A]:
Is pork a necessary ingredient for it?
