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: Yes, nuts are very fatty, and they will eventually go rancidâ if this is the case, they will taste very poor. They can also dry out, or in more rare cases (especially if stored improperly) be infested with insects or molds.Generally, they should be good for six months to a year at their best flavor, depending on the variety (in the shell).Five years is a little long. I am not sure I would want to eat nuts that old.  <sep>  Q: Do nuts ever go bad? A: es, nuts are very fatty, and they will eventually go rancid 
Example Output: What causes them to go rancid?

Example Input: CONTEXT: you know better than I do, it depends on the orange and type of orange. My mom, an executive chef, used to say that you'd allow 1-2 lb of oranges for 1 drinkable cup of orange juice. I really think, that it's highly dependent on the type of orange. I know naval and blood oranges are the juiciest compared to other varieties.  <sep>  Q: How much juice can you get from an orange? A: My mom, an executive chef, used to say that you'd allow 1-2 lb of oranges for 1 drinkable cup of orange juice 
Example Output: Is there a certain method I should use?

Example Input: CONTEXT: The primary reason is definitely convenience. If you don't want skin and seeds in your sauce, then you have to do some work to avoid it. Yes, it's possible, e.g. passing through a food mill, or blanching and peeling plus retaining only the flesh, but having it already done is a whole lot easier.Passata is usually much thicker too, so it won't need as long a cooking time to reduce into a non-watery sauce as fresh tomatoes. On top of that, you don't have to worry about whether you can find good fresh tomatoes, e.g. if it's winter and they're out of season.Your two cases for comparison seem to overlook this: if you just chop and cook, you'll have skin and seeds in your sauce, as well as excess liquid to cook down, while if you use passata, you won't. (Also, for what it's worth, you'd need pretty giant tomatoes to get the equivalent of 3/4 cup of passata out of one tomato.)Of course, if you don't mind skin and seeds, it's also perfectly fine to simply cook fresh tomatoes and be done with it.Note that you can often get similar advantages from other canned tomato products. In the US, crushed tomatoes are far more common, and a roughly similar texture. (Peeled whole tomatoes, diced tomatoes, tomato sauce, and tomato paste can also be useful depending on what texture you're aiming for.)  <sep>  Q: What exactly is Passata? A: crushed tomatoes  Q: Is it better to use Passata instead of fresh tomatoes? A: The primary reason is definitely convenience 
Example Output:
Is the procedure that much more difficult to use fresh tomatoes instead of using Passata?
