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: They're good pretty much forever. There is not enough available water for things to grow in there. Mind you, the more aromatic and subtle parts of the flavor will dissipate over time. The sugar absorbs water, giving the combination a very low water activity, meaning there's little water available for microorganisms to use in growth. As long as your flavoring pieces are small and well mixed with sugar they will not spoil.  <sep>  Q: How long is sugar (mixed with minor ingredients) good for? A: They're good pretty much forever. There is not enough available water for things to grow in there  Q: I mixed them over a year ago, would it still be good? A: As long as your flavoring pieces are small and well mixed with sugar they will not spoil  Q: Some I mixed with lemon/orange zest, will that pose a problem? A: As long as your flavoring pieces are small and well mixed with sugar they will not spoil  <sep> FOLLOWUP_Q: Are you sure it will be safe to use?
Yes

CONTEXT: Our brains are wired to consider food more palatable if the dedicated taste receptors (one of the six basic tastes) for salt are triggered. And in a non-urban world, salt/sodium is a valuable nutrient; the fact we might have it too readily available in the developed world doesn't change that we would DIE on a zero-sodium diet (mind that animal products like meat aren't zero-sodium, and that herbivores tend to love licking salt where they find it!). So our brains have a good evolutionary reason to like salt.Also, salt actively interferes (negatively) with another basic taste receptor - the receptor for bitterness (which can mean poison both in nature and in the developed world, or at least something we have no use for, eg an alkali). Most aromatic food (think green vegetables or spices) is bitter, and salt both attenuates that perception and balances it making the combined food still desirable for our brain. You end up with an even more palatable food since you can use an aromatic (desirable) and shut out the bitterness (not always desirable) response.Umami is a different basic taste, probably related to the presence of protein (glutamate, inosinate, guanylate... trigger it - these are amino acids or salts thereof, and an indicator of easily-digestible protein presence).  <sep>  Q: Why does salt enhance the flavor of food? A: our brains have a good evolutionary reason to like salt  Q: Does salt contain nutrients? A: salt/sodium is a valuable nutrient; the fact we might have it too readily available in the developed world doesn't change that we would DIE on a zero-sodium diet  <sep> FOLLOWUP_Q: Do other animals eat salt?
Yes

CONTEXT: There is some difference between the flavor, but seeing as there are so many other predominant flavors in Worcestershire sauce and that fact that you're (hopefully) not drinking it straight, it's fairly insignificant. It's very common for one product produced in different countries to have a range of manufacturing differences, sometimes arbitrary, sometimes to suit the local palate, and sometimes because of costs, hence people calling American Lea & Perrins a "knockoff."I've had both, and can assure you that once you've mixed it into a casserole or marinade you won't really miss anything. If you're striving for needlessly authentic British flavor you could always add a little malt vinegar to whatever you're cooking!  <sep>  Q: Is there a difference between US Worcestershire sauce and UK Worcestershire sauce? A: There is some difference between the flavor  Q: What is the difference in flavor? A: it's fairly insignificant  Q: Is it true that the US uses distilled white vinegar and the UK uses malt vinegar? A: authentic British flavor you could always add a little malt vinegar  <sep> FOLLOWUP_Q: So, they can be used interchangeably?

No
