GWD3-Q16:
Economist: Tropicorp, which constantly seeks profitable investment opportunities, has been buying and clearing sections of tropical forest for cattle ranching, although pastures newly created there become useless for grazing after just a few years. The company has not gone into rubber tapping, even though greater profits can be made from rubber tapping, which leaves the forest intact. Thus, some environmentalists conclude that Tropicorp has not acted wholly out of economic self-interest. However, these environmentalists are probably wrong. The initial investment required for a successful rubber-tapping operation is larger than that needed for a cattle ranch. Furthermore, there is a shortage of workers employable in rubber-tapping operations, and finally, taxes are higher on profits from rubber tapping than on profits from cattle ranching.
In the economist’s argument, the two boldfaced portions play which of the following roles?
A. The first supports the conclusion of the economist’s argument; the second calls that conclusion into question.
B. The first states the conclusion of the economist’s argument; the second supports that conclusion.
C. The first supports the environmentalists’ conclusion; the second states that conclusion.
D. The first states the environmentalists’ conclusion; the second states the conclusion of the economist’s argument.
E. Each supports the conclusion of the economist’s argument.
正确答案为：C
为什么D不对？
因为文中说some environmentalists conclude that….后面接着说However,，在后面就是经济学家的辩驳。D中说的第二个黑体字正好是说经济学家要辩驳的结论。
请解释一下，谢谢……
求求牛牛来解释解释啊……
恩，我觉得的是这样的，D选项的后一句话是对的，的确是经济学家要反驳的观点，但是第一句话表述错了，不是环境学家最后形成的观点，这句话的作用是用来支持环境学家最后观点的一个有利证据而已。你可能是前一句话的表述没有看仔细。
