Reаd the fоllоwing pаssаges and determine the authоr’s implied topic and main idea. Passage C The Aswan High Dam, built in Egypt with Russian support, was supposed to provide hydroelectric power and to increase Egypt’s food supply by controlling the unpredictable Nile River. The project meant that great art treasures were flooded as submerged land was drained for cultivation. However, only one-tenth of an acre of land was made available for each person added to Egypt’s population during the period of construction. One result of the dam was that the Nile no longer flooded the delta farmlands annually. These annual floods served to restore the farmland fertility with deposited silt. This no longer the case, the quality of the farmland decreased. The dam also cut off the nutrients that had been washed to the Mediterranean Sea as a result of the annual floodings. Because of this, or the change in the salinity of the sea that the dam produced, the sardine catch dropped from 18,000 tons per year to 500 tons per year. The stable lake created by the dam allowed aquatic snails to flourish. The snails serve as an intermediate host to a blood fluke that bores into humans causing the dreaded disease, schistosomiasis. The construction of that dam had important political implications at the time.

Dоnаtо, Jоlene, аnd Cаrol are neighbors. They each have young children, and the three of them – Donato, Jolene, and Carol - decide to build a waterslide for their children to enjoy. They also agree to split the cost of fixing the waterslide if anything happens to it. Eventually, the slide breaks, and it will cost $210 to repair it. Jolene proposes that they instead buy a new slide for $450. Donato agrees and they purchase it without speaking to Carol. For how much of the cost is Carol responsible?
