Answer to Question 1

As crystals form from a cooling melt, they selectively remove certain elements from the magma; this is magmatic differentiation. As this occurs, it leaves the remaining liquid portion of the melt depleted in the elements that have been removed by the formation of certain minerals. Should those first minerals that crystallize settle or the remaining melt inject into a fracture or erupt, the minerals that crystallize from that remaining melt will be of a different composition than the first minerals to form, resulting in different igneous rock originating from the same initial melt.

Answer to Question 2

C

People who have myopia, or nearsightedness, are not able to see objects at a distance but only up close. It occurs when the cornea is either curved too steeply, the eye is too long, or both. This condition is progressive and worsens with time. More than 100 million people in the United States are nearsighted, but only 20% of those are born with the condition. Diet, eye exercise, drug therapy, and corrective lenses can all help manage nearsightedness.
