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.

A. Today’s libraries are pleasingly different from what they were fifty years ago. B. Today’s libraries offer a wide variety of books, magazines, audio books, videos, CDs, and DVDs. C.

Read the following passage and determine the author’s topic. Passage B Child labor is in great demand for several reasons. Children are more docile than adults, easier to discipline, and more often too frightened to complain. Their small frames and nimble fingers are considered an asset for certain kinds of work. Although only 7 to 10 years old, they are forced to work 12 to 14 hours a day. Most important, child labor is quite cheap; children are generally paid less than one-third of the adult wage. Not surprisingly, when children are given jobs, their parents may lose theirs.
