Instructions: Given a scientific passage and an answer, generate a question for the given answer.
Input: Passage: About 5% of earthquakes take place within a plate, away from plate boundaries. These intraplate earthquakes are caused by stresses within a plate. Since plates move over a spherical surface, zones of weakness are created. Intraplate earthquakes happen along these zones of weakness. The earthquakes may take place along ancient faults or rift zones. Answer: 5%
Output:
What is the percentage of earthquakes that take place within a plate, away from plate boundaries?
