Answer to Question 1

A

Answer to Question 2

Galaxies are much closer together, relative to their size, than stars are. If the Sun were made the size of a grapefruit, the nearest star would be on the other side of the continent. However, if the Milky Way (or any other galaxy) were made the size of a grapefruit, there would likely be another galaxy within a few feet of it. Thus, galaxy interactions are far more common than star-star interactions and must be taken into account when considering galaxy evolution.
