You will be given a definition of a task first, then some input of the task.
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:'.

CONTEXT: The old thin utensils were made of Nylon.The reasons they are hard to find is that traditional Nylon is difficult to manufacture within food standard guidelines for PAA (Primary Aromatic Amines) migration, and does not bio-degrade or burn safely. For relevant references, your local government health department will have papers on PAA migration.Given that, many utensil manufactures have moved on to other plastics, mostly silicone. Though some use PA66 (Nylon 6,6), which is that thick chunky black plastic stuff.Try wooden spatulas. They are simple, clean, disposable, and you can get them in thin wedge shapes (e.g. at Asian supply shops).  <sep>  Q: Where did the thin, smooth plastic spatulas go?###20 years ago, the most common type of rigid spatula (or "turner") was smooth, thin (as in 3mm or less with a sharp edge), and generally made of nylon.### These spatulas were not very durable (leading edges tended to melt), but they were very very good for making eggs and other delicate non-stick-pan dishes. A: they are hard to find is that traditional Nylon is difficult to manufacture within food standard guidelines for PAA (Primary Aromatic Amines) migration, and does not bio-degrade or burn safely  <sep> FOLLOWUP_Q: Why did manufacturers stop making thin, smooth plastic turner spatulas?
Output:
