The document helps you answer the question because it shows the importance of the Nile to the people of Egypt. Because the Nile was one of the more prominent waterways that runs though Egypt, it helped provide them with food, transportation, and other necessities to live. Lines like [insert lines 3-6] help prove the above, as it shows how much the Egyptians relied on the river not only to live, but to advance as a civilization.
Hope this helps! :)
