You are presented with the question "What causes volcanic eruptions?" and the following answer choices: 
- a hemisphere is tilted away from the sun
 - high-mass stars collapsing
 - tectonic plates being pushed together
 - Two things found in Florida
 - Two things that come together in San Andreas
 - Two things found in Washington DC
 - Sudden shaking of the ground.
 - Two things found in Manhattan

Now knowing that the movement of tectonic plates causes volcanic eruptions and the San Andreas is a "transform fault" that marks the boundary between two tectonic plates --  the North American and the Pacific, choose the best answer.
