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:`.

Q: 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 add flour to sour culture ? A: Remove and discard (or use elsewhere) half or more of starter. Add fresh flour and water in the desired proportions  <sep> FOLLOWUP_Q: do you have any other tips on how I can add the flour to the sour culture ?

A: Yes

Q: CONTEXT: During blending, air is put into the milk mixture. Once you switch it off, not all air is kept inside the milk but makes it's way to the surface. These are the bubbles that make you think your milk is fizzy.Without being a chemist I assume full fat milk has more fat, therefore the emulsion is somewhat "thicker" and thus can hold the air better. There are also bubbles with full fat milk, but less than with skimmed milk. Sort of.  <sep>  Q: Why is the skimmed milk fizzy? A: During blending, air is put into the milk mixture. Once you switch it off, not all air is kept inside the milk but makes it's way to the surface  Q: Why does that not happen when using whole milk? A: Without being a chemist I assume full fat milk has more fat, therefore the emulsion is somewhat "thicker" and thus can hold the air better  Q: Is it normal to hear a fizzing sound coming from the bubbles? A: There are also bubbles with full fat milk, but less than with skimmed milk. Sort of  <sep> FOLLOWUP_Q: Is there anything I can do to ensure that the bubbles don't form?

A: No

Q: CONTEXT: Whiskey is quite high in alcohol, on the order of 40% by volume, and is not hospitable to pathogens growing.The flask is intended to hold liqueur, and so is made from or lined with a food safe material, such as food grade stainless steel (assuming you have one from a reputable manufacturer).So yes, it should be fine. Remember: when it was brewed, the whiskey was probably held at different stages for long periods in a stainless steel vat.  <sep>  Q: I have had some whisky inside a metal flask for a month and was wondering if it was safe to drink? A: Whiskey is quite high in alcohol, on the order of 40% by volume, and is not hospitable to pathogens growing  Q: Would this be the same for a stainless steel flask? A: The flask is intended to hold liqueur, and so is made from or lined with a food safe material, such as food grade stainless steel (assuming you have one from a reputable manufacturer  <sep> FOLLOWUP_Q: I am happy it will be safe! Will the taste be effected at all?

A:
No
