　　托福阅读修辞目的题例题

　　例题8：

　　Paragraph 3: The first wells were drilled into the Ogallala during the drought years of the early 1930’s. The ensuing rapid expansion of irrigation agriculture, especially from the 1950’s onward, transformed the economy of the region. More than 100,000 wells now tap the Ogallala. Modern irrigation devices, each capable of spraying 4.5 million liters of water a day, have produced a landscape dominated by geometric patterns of circular green islands of crops. Ogallala water has enabled the High Plains region to supply significant amounts of the cotton, sorghum, wheat, and corn grown in the United States. In addition, 40 percent of American grain-fed beef cattle are fattened here.

　　In paragraph 3, why does the author provide the information that 40 percent of American cattle are fattened in the High Plains?

　　To suggest that crop cultivation is not the most important part of the economy of the High Plains

　　To indicate that not all economic activity in the High Plains is dependent on irrigation

　　To provide another example of how water from the Ogallala has transformed the economy of the High Plains

　　To contrast cattle-fattening practices in the High Plains with those used in other region of the United States
