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: Anything can spoil eventually, refrigerated or not. Keeping something under a lid and refrigerated restricts the number of airborne colonizers that might get access to it, and the cold temperature means that even if they get there, they will grow much slower than at room temperature.For something to spoil, it needs to be colonized by bacteria or fungus spores, and it needs to contain some nourishment to support their growth, not too much chemicals that prevent their growth, and not too much competing life forms already present. So, things with a high concentration of salt or sugar tend to be unhospitable to bacteria and fungi growth, because they are hygroscopic (they draw the water out of cells). Extreme high or low pH (eg acidic) also retards growth. Think of things like ketchup, mustard, jelly with labels that say "refrigerate after opening" but most people ignore them. Alcohol is unfriendly if the concentration is too high, and of course natural fermented foods are already occupied by human-friendly bacteria.Ketchup is sealed in a bottle, usually with no fingers or utensils inserted into it, so it stays pretty sterile. It is also protected by being hygroscopic (due to high concentration of sugar and salt) and its acidity. Ketchup as a word and concept is descended from an Indonesian fish sauce, and has been around much longer than refrigeration. I think you can leave it out with no worries unless you see obvious mold growth.  <sep>  Q: Does ketchup belong in the fridge, or the cupboard? A: has been around much longer than refrigeration. I think you can leave it out with no worries unless you see obvious mold growth  Q: What type of mold can grow on ketchup? A: For something to spoil, it needs to be colonized by bacteria or fungus spores 
Example Output: What can happen if I eat ketchup that is spoiled?

Example Input: CONTEXT: 'Paella rice' is not actually a variety of rice, but a category suitable, as the its name suggests, for making paella. Some common varieties are: Bahia, Balilla, Bomba, Senia, and Calasparra; the particular variety should be indicated on the packet that you choose.These varieties differ from risotto rices, such as arborio and carnaroli, in not creating a creamy 'sauce' around the rice. Paella rice should stick together, but be distinct and not in a creamy 'sauce'.Arborio rice has a creamy, chewy texture due to its higher amylopectin (one of two components in its starch) content. Paella rice absorbs more liquid than risotto rices, however it too would become 'creamy' if you stirred it like a risotto, since it also has a high starch content.  <sep>  Q: What is the difference between risotto rice and paella rice? A: Paella rice' is not actually a variety of rice, but a category suitable, as the its name suggests, for making paella 
Example Output: What is is made of?

Example Input: CONTEXT: Thanks for adding the photo, Ford, as I think I know what it is. Although your photo is nicely focused, it's not the real thing so I can't be 100% sure. It looks to be the built up bits of grease and other residues from the bottom of your cooking pans that have accumulated over the 5 years. Not saying you slopped lots but the smallest amounts of spatter from cooking will add up. I moved 6 months ago into a place with a new stove and I've done my best not to spill food and to always wipe up right away but I've noticed the burners getting marked. It doesn't wash off either. Do you find the elements you cook on the most are more marked?But to answer your original question whether the scratches affect the burners' performance, the answer is no. All they need to be able to do is heat up and even a knick in the metal wouldn't stop it from heating.  <sep>  Q: Do scratches on electric range burner elements affect its performance or function? A: the answer is no 
Example Output:
Is there a way to replace the coating on the heating elements?
