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

Example Input: Passage: Less dramatic types of mass wasting move Earth materials slowly down a hillside. Slump is the sudden movement of large blocks of rock and soil down a slope. ( Figure below ). All the material moves together in big chunks. Slumps may happen when a layer of slippery, wet clay is underneath the rock and soil on a hillside. Or they may occur when a river (or road) undercuts a slope. Slump leaves behind crescent-shaped scars on the hillside. Answer: slump
Example Output: What is the term for the sudden movement of large blocks of rock and soil down a slope?

Example Input: Passage: Landslides are the most dramatic, sudden, and dangerous types of mass wasting. Landslides are sudden falls of rock; by contrast, avalanches are sudden falls of snow. Answer: landslides
Example Output: What are the most dramatic, sudden, and dangerous types of mass wasting?

Example Input: Passage: Skeletons made of cartilage rather than bone. Cartilage is supportive tissue that does not have as much calcium as bones, which makes bones rigid. Cartilage is softer and more flexible than bone. Answer: calcium
Example Output:
What does cartilage lack compared to bones, making it softer and less rigid?
