Given a paragraph about cooking, and a set of conversational question answers about the paragraph, answer a follow-up question from the paragraph. The paragraph has a prefix 'CONTEXT:'. Each conversation question has a prefix 'Q:' followed by answer prefix 'A:'. The final followup question has a prefix 'FOLLOWUP_Q:'.
One example: CONTEXT: What I've done in the past is mist some water on both sides of the bread slices, then put them in the microwave for 10-15 seconds (alternatively, an oven set at 300F/150C for 5-10 minutes will do it too).Experiment with the amount of water (but keep it low) and cooking times. You should get much softer (and warm) bread slices out of it.  <sep>  Q: How do I make whole multi grain bread softer? A: mist some water on both sides of the bread slices  <sep> FOLLOWUP_Q: Does that make it soggy?
Solution is here: Experiment with the amount of water (but keep it low)
Explanation: Here the follow-up question asks about a way to make the bread softer. The answer (Experiment with the amount of water) is mentioned in the passage.

Now, solve this: CONTEXT: In a cookbook that old, the sour cream referenced is probably a home-fermented variety, used as a preservation method in the days before widespread home refrigeration. You can still do this with the appropriate bacterial cultures, but most of us now buy our sour cream at the store instead. That product is similar, but made in much larger batches with a highly standardized, refined bacterial culture, producing a product with a predictable sourness and texture. Home-cultured versions are more variable, but they use similar processes on a much smaller scale.Whether you want to call this the "same" is partly a linguistic distinction that depends on how much you want to consider the differences in scale and equipment between pre-refrigeration and modern methods.In contrast, the addition of something sour to cream is really a substitute, used when you don't have a proper sour cream available. A cook back in the 1890s could use the same substitution then as we might today. But the production of sour cream (and all sorts of fermented milk products, such as yogurt and kefir) is much older than that, and there would have been some variety of "traditional" sour cream available, though not universally or year-round in the days before mechanized food distribution systems.  <sep>  Q: Is sour cream in olde recipes the same as sour cream today? A: the sour cream referenced is probably a home-fermented variety, used as a preservation method in the days before widespread home refrigeration  <sep> FOLLOWUP_Q: How would I make a home-fermented variety of sour cream?
Solution:
You can still do this with the appropriate bacterial cultures, but most of us now buy our sour cream at the store instead
