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:'.

Input: Consider Input: CONTEXT: Substitution in preserved foods are generally considered unsafe. Food chemistry is a complicated affair, and cooking is inherently imprecise. Sure, you can find a way to reduce the pH to that of the original recipe. But a salami is a fermented food. Your pH might be the same, but other things will change, for example the composition of the available sugars, and you can catch a different strain of bacteria. Safe preservation recipes have either been extensively tested in a lab, or used for centuries. Making a small change can destroy the delicate balance which leads to a tasty, safe food. The solution here is to look for another recipe, one which is safe but does not contain wine. For something as risky as cured meat, I'd suggest not getting some random recipe off the Internet, but choosing from a book, or maybe from the blog of a known, respectable author. This way, you get both good taste and safety, things which are hit-and-miss when making your own substitutions. <sep> Q: What can you substitute for wine when making homemade salami? A: The solution here is to look for another recipe, one which is safe but does not contain wine Q: Most of the recipes I found use wine. Would citric acid work as a replacement? A: Substitution in preserved foods are generally considered unsafe <sep> FOLLOWUP_Q: So is the wine used as a preservative?

Output: Yes

Input: Consider Input: CONTEXT: Mast O Khiar, as you mention mainly consist of plain yogurt and cucumbers and most recipe do not require much more than that. Because of such, the shelf life for the yogurt product will be the shelf life of the yogurt itself. If it is a store bought yogurt, then the shelf life should be about 2 weeks in the refrigerator.Make sure to store the sauce in an air-tight container. Most tubberware should work. Those soup containers from Chinese takeout orders work perfectly.EDIT: After a bit of a debate in cooking chat, I decided to change my answer a little. The reason I said 2 week is because personally I had eaten 2 week old Mast O Khiar. However it could be recipe dependant so it could be different for a different recipe. However it is very easy to tell whether yogurt OR cucumber is bad.Mast O Khiar should have a very fresh/clean aroma. When yogurt turn bad, it releases a rancid smell. If it smells bad, dont eat it.If you see fuzzy mold it's a good idea to throw it out. <sep> Q: I made kubideh kabobs with saffron rice for my fiance and I last night, and it was a huge success. However, my fiance wished we had some mast o khiar (yogurt-cucumber sauce) to go with it, as what we would normally get from a kabob takeout place### Now, given that this is the first time Persian food has ever been made in this house, I have concerns about any reasonably sized batch of this yogurt sauce being consumed in time. A: Mast O Khiar, as you mention mainly consist of plain yogurt and cucumbers and most recipe do not require much more than that <sep> FOLLOWUP_Q: how long might this be safely stored in a refrigerator?

Output: Yes

Input: Consider Input: CONTEXT: What you're describing is something that I'd consider normal in a cookie. Some cookies are more cake-like, some are chewy, some are crunchy, some are flatter than others - but they're all good. Almost any factor - from the type of fat, to the type of liquid, to the leavener, to the temperature of both the oven and the dough can affect the cookie's texture. I'd make two recommendations if you want your cookie less flat: 1) chill the dough for a few hours, or overnight. Then, form them and get them into the oven quickly, while the dough is stone cold. 2) Try a different recipe. Do a visual internet search for the type of cookie that you're after. Good recipes are hard to find, and sometimes you have to kiss a few frogs... <sep> Q: Why aren't my chocolate chip cookies coming out the way I'd like them? A: Almost any factor - from the type of fat, to the type of liquid, to the leavener, to the temperature of both the oven and the dough can affect the cookie's texture Q: I'm making chocolate chip cookies. Am I doing something wrong if my cookies look flat on top, and soft, and brown on the bottom? A: What you're describing is something that I'd consider normal in a cookie. Some cookies are more cake-like, some are chewy, some are crunchy, some are flatter than others - but they're all good Q: They're soft on top and are crunchier at the bottom. They taste fully cooked and good, but not exactly like cookies should right? A: if you want your cookie less flat: 1) chill the dough for a few hours, or overnight. Then, form them and get them into the oven quickly, while the dough is stone cold. 2) Try a different recipe Q: So you don't think I cooked them wrong? A: they're all good Q: What else can be done that affects the texture of the cookies? A: Almost any factor - from the type of fat, to the type of liquid, to the leavener, to the temperature of both the oven and the dough can affect the cookie's texture <sep> FOLLOWUP_Q: Do you have a prefrence on how your cookies come out?
Output: Yes
