Plate Boundaries
Explanation:
Puerto Rico might be on a plate boundary. When two plates slide against each other (also called a transform boundary) they can cause a earthquake to happen on the surface.
The best method for studying both the structure and the function of the brain would be the functional magnetic resonance imaging (fMRI).
This technique measures the blood flow to different brain regions in order to determine which areas are active in certain brain processes. An increase in the blood flow increases the amount the oxygen the area is receiving that is needed for the functioning of the nerve cells.
