instruction:
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:'.
question:
CONTEXT: There's always the delight of botulism, which thrives in the anaerobic environment provided by vacuum packing. Listeria and vibrio bacteria can grow in an anaerobic environment, and are potential food safety risks present in fish. With this in mind, I would not expect vacuum packing to extend the life of a fish much. It will reduce freezer burn though! <sep> Q: How long can I keep thawed vacuum-packed fish in the fridge?
answer:
No

question:
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?
answer:
Yes

question:
CONTEXT: Bananas are imported unripe and then ripened in the country of sale. This ripening is achieved by forcing ethylene gas through the bananas in special pressurised rooms.Bananas naturally produce ethylene as they ripen, so you could just put them in a sealable plastic bag to contain that gas. Tomatoes also produce ethylene, so you could pop a couple of those in as well, but be aware that they'll also ripen faster too. <sep> Q: How can I speed up banana ripening?### A: Bananas naturally produce ethylene as they ripen, so you could just put them in a sealable plastic bag to contain that gas Q: Do you know of another way? A: Bananas are imported unripe and then ripened in the country of sale. This ripening is achieved by forcing ethylene gas through the bananas in special pressurised rooms <sep> FOLLOWUP_Q: Does the gas cause the flesh to ripen or just the skin to change?
answer:
No
