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: A lot of sourdough recipes don't call for a sponge, per se, because the starter essentially already is a sponge. The purpose of a sponge in a bread with normal yeast is to allow a longer fermentation time and extra time for enzymatic reactions to happen in the flour before adding it to the final batch. This isn't necessary with sourdough the starter is continuously fermenting and reacting. And your guess is about right, if the proportion of starter you add is too high, the waste products and dead yeast cells in it can cause changes in the gluten that make it very slack and unusable.  <sep>  Q: How does a sourdough sponge work? A: The purpose of a sponge in a bread with normal yeast is to allow a longer fermentation time and extra time for enzymatic reactions to happen in the flour before adding it to the final batch  Q: Why is it important to increase the fermentation time ? A: The purpose of a sponge in a bread with normal yeast is to allow a longer fermentation time and extra time for enzymatic reactions to happen in the flour before adding it to the final batch  <sep> FOLLOWUP_Q: wouldn't the sourdough break down the gluten in the sponge ?

Yes
