Paragraph 10: The extreme seriousness of desertification results from the vast areas of land and the tremendous numbers of people affected, as well as from the great difficulty of reversing or even slowing the process. Once the soil has been removed by erosion, only the passage of centuries or millennia will enable new soil to form. In areas where considerable soil still remains, though, a rigorously enforced program of land protection and cover-crop planting may make it possible to reverse the present deterioration of the surface.
11. It can be inferred from the passage that the author most likely believes which of the following about the future of desertification?
○Governments will act quickly to control further desertification.
○The factors influencing desertification occur in cycles and will change in the future.
○Desertification will continue to increase.
○Desertification will soon occur in all areas of the world.
