Given scientific fact as input, generate the question from this fact such that it can be answered from the input.

Example Input: Renewable energy sources emit fewer or no greenhouse gases.
Example Output: What type energy sources emit fewer or no greenhouse gases?

Example Input: Sucrose is formed when a monomer of glucose and a monomer of fructose are joined in a dehydration reaction to form a glycosidic bond.
Example Output: What is formed when a monomer of glucose and a monomer of fructose are joined in a dehydration reaction to form a glycosidic bond?

Example Input: Proper kidney function is essential for homeostasis of ph level, which in turn helps ensure the functioning of enzymes.
Example Output:

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.
