Given a scientific passage and an answer, generate a question for the given answer.

Example Input: Passage: Mixtures have different properties depending on the size of their particles. Three types of mixtures based on particle size are solutions, suspensions, and colloids, all of which are described in Table below . You can watch videos about the three types of mixtures at these URLs:. Answer: solutions, suspensions, colloids
Example Output: What are the three types of mixtures?

Example Input: Passage: Pressure is the result of force acting on a given area. It can be represented by the equation:. Answer: pressure
Example Output: What property is the result of force acting on a given area?

Example Input: Passage: In a marine ecosystem, algae are the producers. Through photosynthesis, they provide glucose for the ecosystem. So, can too much algae be a bad thing? Eutrophication is an over-enrichment of chemical nutrients in a body of water. Usually these nutrients are the nitrogen and phosphorous found in fertilizers. Run-off from lawns or farms can wash fertilizers into rivers or coastal waters. Answer: photosynthesis
Example Output:
Through this process, algae provide glucose for the ecosystem?
