TASK DEFINITION: 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:`.
PROBLEM: 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?

SOLUTION: Yes

PROBLEM: CONTEXT: It really depends on the density of the bottom sponge. If it's too light, you might have a problem. To be doubly sure, take some wide straws (the ones about 1cm across) stick them in the bottom layer, then snip them flush. These will act like columns to support the top cake.  <sep>  Q: Is it possible to stack the top tier cake without using a cake board? A: It really depends on the density of the bottom sponge. If it's too light, you might have a problem  <sep> FOLLOWUP_Q: What can I do to make sure to avoid that problem?

SOLUTION: Yes

PROBLEM: CONTEXT: The frying pain is still safe to use (unless the ceramic chipped or cracked badly as well). A bit of vinegar (white) and a soft scrubber may get the rest of those burnt bits out as well. Either way, though, as long as the ceramic is intact, you can still use the frying pan safely.  <sep>  Q: Is burnt ceramic frying pan safe to use? A: The frying pain is still safe to use (unless the ceramic chipped or cracked badly as well  Q: Do you know of any way to clean it? A: A bit of vinegar (white) and a soft scrubber may get the rest of those burnt bits out as well  <sep> FOLLOWUP_Q: Is there anything else I should know about it?

SOLUTION:
Yes
