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: The ripening itself is caused by ethylene gas released by the food, which is trapped by any kind of bag.As far as I know, there's nothing inherently special about a brown paper bag, other than the fact that it's porous and thus still allows some air to get in and out. Plastic ziplock bags have no ventilation, so they don't work nearly as well.  <sep>  Q: Why does a brown paper bag speed ripening? A: The ripening itself is caused by ethylene gas released by the food, which is trapped by any kind of bag  <sep> FOLLOWUP_Q: Is there data that proves this?

SOLUTION: No

PROBLEM: CONTEXT: I think you've answered your question yourself. You use the bean itself to make vanilla sugar, so obviously there is much flavour in it as well and not just in the seeds.My experience is that you get much more flavour out of the pod if you let it simmer in warm milk/fluid.  <sep>  Q: Is there really a difference by throwing the vanilla pod in as well? A: My experience is that you get much more flavour out of the pod if you let it simmer in warm milk/fluid  <sep> FOLLOWUP_Q: Do recipes just ask you to do so, because you'd get more seeds in the milk or cream, or does the pod itself give a special flavour?

SOLUTION: Yes

PROBLEM: CONTEXT: There could be two factors involved. First, the freshness of the celery. Restaurants, especially those that serve large amounts, are going through a lot of product. This means that you are more likely to get really fresh celery.Next, storing in water is very likely an issue. I would suggest buying celery within a day or so of when you plan to use it. Wash and dry it thoroughly. Then trim and cut to your desired size. Then immediately place the celery in a plastic container or zipper bag and place in the refigerator until serving.Each time you take it out for serving, remove the amount you plan to use and return the rest to the refrigerator. The 'leftover' celery should remain fresh and crisp for several days.  <sep>  Q: Why does raw celery from a restaurant taste different than raw celery at home? A: First, the freshness of the celery. Restaurants, especially those that serve large amounts, are going through a lot of product. This means that you are more likely to get really fresh celery  Q: I store my celery in water, shouldn't that keep it fresh? A: Wash and dry it thoroughly. Then trim and cut to your desired size. Then immediately place the celery in a plastic container or zipper bag and place in the refigerator until serving  <sep> FOLLOWUP_Q: I always thought I did it the best way, are there any other possible reasons restaurant celery tastes better?

SOLUTION:
Yes
