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

Example Input: Passage: To help digest the large amount of plant material, the stomach of the ruminants is a multi-chambered organ, as illustrated in Figure 34.8. The four compartments of the stomach are called the rumen, reticulum, omasum, and abomasum. These chambers contain many microbes that break down cellulose and ferment ingested food. The abomasum is the "true" stomach and is the equivalent of the monogastric stomach chamber where gastric juices are secreted. The four-compartment gastric chamber provides larger space and the microbial support necessary to digest plant material in ruminants. The fermentation process produces large amounts of gas in the stomach chamber, which must be eliminated. As in other animals, the small intestine plays an important role in nutrient absorption, and the large intestine helps in the elimination of waste. Answer: four
Example Output: How many stomach compartments do ruminants have?

Example Input: Passage: As you would expect, where plates collide there are lots of intense earthquakes and volcanic eruptions. The subducting oceanic plate melts as it reenters the mantle. The magma rises and erupts. This creates a volcanic mountain range near the coast of the continent. This range is called a continental arc . The Andes Mountains, along the western edge of South America, are a volcanic arc ( Figure below ). Answer: melts
Example Output: The subducting oceanic plate does what as it reenters the mantle?

Example Input: Passage: Photosynthesis is the process by which plants use energy from sunlight to synthesize carbohydrates. Answer: photosynthesis
Example Output:
What is the name of the process by which plants use energy from sunlight to synthesize carbohydrates?
