Definition: 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: 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 ?

Yes
