Answer to Question 1

A

Answer to Question 2

Answer: This is the setting for a continental volcanic arc. The volcanoes are most likely to be composite volcanoes, with andesitic compositions that are typically very explosive. Pyroclastic flows, ash falls, and lahars would be at the top of the risk list, though lava flows may also occur.
