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:`.

Example Input: CONTEXT: The feeding/maintenance of your starter is the same regardless of flour. Remove and discard (or use elsewhere) half or more of starter. Add fresh flour and water in the desired proportions. Stir. As your starter matures, it becomes acidic. Too much acidity interferes with yeast activity in the bread making process. That is why you need to remove a portion of the "spent" starter each time you feed.  <sep>  Q: How do I feed a sour culture? A: Remove and discard (or use elsewhere) half or more of starter  Q: What goes into the starter? A: Add fresh flour and water in the desired proportions  Q: Is 70g flour and 70g warm water the correct proportions? A: Add fresh flour and water in the desired proportions. Stir. As your starter matures, it becomes acidic 
Example Output: Is there a specific type of flour I should use?

Example Input: CONTEXT: Buckwheat seems to have fallen out of favor in the US. In other countries it is still a staple.In Russia buckwheat (grechka) is eaten as a hot cereal- just boil it until it bursts and add some sweetened condensed milk. Delicious. In fact- the best way I have purchased it locally is by finding international grocery stores that have a Russian section.It has a very distinctive nutty, earthy flavor. You would recognize it if you have had it so it seems unlikely to me that there might be some clandestine usage and you are "out of the loop" at all.Although it is very nutritious (a whole grain and all), it is used in pancakes just for the flavor. It's usage in pancakes seems to be purely traditional and taking informal surveys of my friends (in Texas) it is uncommon for anyone to know what it is at all.  <sep>  Q: Why Buckwheat Pancakes? A: whea  Q: Yes A: Buckwheat seems to have fallen out of favor in the US. In other countries it is still a staple  Q: Where is buckwheat harvested? A: the best way I have purchased it locally is by finding international grocery stores that have a Russian section 
Example Output: How much does buckwheat cost?

Example Input: CONTEXT: As someone who uses liquid nitrogen as part of their daily routine (in a lab) and who has made liquid nitrogen ice cream on several occasions, my advice would be to not use a plastic container to hold liquid nitrogen unless it's designed to. Yes, the plastic vessel may become brittle and may fracture. I have seen some materials shatter with extreme violence when frozen with liquid nitrogen; do not attempt this. Vessels for handling cryogenic liquids are designed especially for the job, and made from materials such as stainless steel, styrofoam, teflon, HDPE or silvered borosilicate glass. Unless you know with certainty that your container is designed to withstand temperatures of -196 Â°C (-321 Â°F), do not attempt this procedure.  <sep>  Q: Can you use liquid nitrogen in a food processor?###Will this break the container since it isn't made of steel? A: As someone who uses liquid nitrogen as part of their daily routine (in a lab) and who has made liquid nitrogen ice cream on several occasions  Q: Will using liquid nitrogen in the container harm the food?###Do you know if anyone has tried it? A: the plastic vessel may become brittle and may fracture. I have seen some materials shatter with extreme violence when frozen with liquid nitrogen; do not attempt this  Q: What kind of container would you recommend for this process? A: Vessels for handling cryogenic liquids are designed especially for the job, and made from materials such as stainless steel, styrofoam, teflon, HDPE or silvered borosilicate glass 
Example Output:
Which type of container will retain the temperature of the food better?
