Task: Question Generation
Input (English): Background Paragraph: Almost all earthquakes occur at plate boundaries. All types of plate boundaries have earthquakes. Convection within the Earth causes the plates to move. As the plates move, stresses build. When the stresses build too much, the rocks break. The break releases the energy that was stored in the rocks. The sudden release of energy is an earthquake. During an earthquake the rocks usually move several centimeters. Rarely, they may move as much as a few meters. Elastic rebound theory describes how earthquakes occur ( Figure below ). 
Story: Geologists have been contemplating on the question - why some places are more susceptible to earthquakes. To understand the differences, they have made a chart where they divided the earth into two regions, region A and region B. In region A many earthquakes happen, but in region B no earthquakes happen.
Output (English): In which region the plates would move, region A or region B?
