Please, read the short five paragraphs in order to solve the last three multiple choice questions.
1 In the 1930s, a terrible drought struck the Great Plains in the central United tates. Ihis region is naturally semi-arid, so it rarely gets plenty of rain. But in the 1930s, the dryness was severe. Strong winds picked up the dry soil and blew it hundreds of miles away. Many farmers left, abandoning their homes and giving up their farms. What happened to the land is known as desertification, the process by which semi-arid land changes into a desert. Desertification can occur naturally as the climate gradually changes and areas become drier. However, it can also occur when human activities put too much stress on the land. Today, as during the 1930s, desertification has devastated the lives of many people, and people themselves are partly to blame. 2 The problem in the Great Plains started in the 1920s, when new types of farm machinery allowed farmers to plant larger crops more quickly. Farmers used the machinery to cultivate many more acres of land than they had previously-about 5 million acres more. Much of that land had been covered with a drought-resistant grass native to the region. Farmers plowed the land, killed the grass, and planted wheat, which is not resistant to drought. 3 As long as there was enough rainfall, the wheat grew. But a long drought struck during the 1930s. The region usually survives dry periods, but in this case, people made the situation worse. Even as the drought deepened, farmers kept pl planting. Without water, the wheat did not grow. The soil was exposed to the sun and wind, and desertification occurred owing and 4 Today, the Great Plains area has recovered from the desertification of the 1930s It is once again a productive farming region. And farmers today follow bet agricultural practice around the world. A case in point is the Sahel, a region of West Africa. In 1968, s. But desertification has continued to threaten other placesExplanation / Answer
