Answer 2

The correct answer is: It provides a visual reference to the reader.

Sometimes when reading a bunch of information it is difficult to understand and picture everything. By having a map, the reader doesn't have to only imagine the information, but he/she can also look and the whole understanding of the theme gets easier with visual aid.
