Question

Which ancient civilization relied primarily on underground rivers, springs, and lakes to support their cities?

Answer 1

The ancient civilization that relied primarily on underground rivers, springs, and lakes to support their cities was Egypt. This is also as a result of the Nile river.

Answer 2

The answer is C) Egyptian.   
   The Egyptians had good sources of water so it was natural for them to learn how to use them in the best way.  The Nile river was the most useful source, but other lakes/rivers were also used. The Manzala Lake, being a saltwater lake, was practically useless other than for fishing. Aswan (Nasser) Lake was located behind the Nile river and was used for farming.
   These lakes/rivers were used for Irrigation, canals, and fishing.
