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 argue that Tropicorp’s actions do not serve even its own economic interest. However, the initial investment required for a successful rubber-tapping operation is larger than that needed for a cattle ranch; there is a shortage of workers employable in rubber-tapping operations;and taxes are higher on profits from rubber tapping than on profits from cattle ranching.

Consequently, the environmentalists’ conclusion is probably wrong.

In the economist’s argument, the two boldface portions play which of the following roles?

The first supports the conclusion of the economist’s argument; the second calls that conclusion into question The first states the conclusion of the economist’s argument; the second supports that conclusion The first supports the conclusion of the environmentalists’ argument; the second states that conclusion The first states the conclusion of the environmentalists’ argument; the second states the conclusion of the economist’s argument Each supports the conclusion of the economist’s argument

题干翻译
Tropicorp公司将部分热带森林用于养牛场，尽管新开辟的牧场几年后就无法用于放牧。该公司没有从事橡胶采集，即使橡胶采集能带来更大利润且能让森林保持完整。因此，一些环保主义者认为Tropicorp的行为甚至不符合其自身经济利益。然而，成功的橡胶采集业务所需的初始投资比养牛场大；橡胶采集业务可雇佣的工人短缺；橡胶采集利润的税收比养牛场利润的税收高。因此，环保主义者的结论可能是错误的。 逻辑链
1. 环保者观点：Tropicorp行为不符自身经济利益 2. 经济学家观点：环保者结论错 问题类型
句子作用题 推理过程
文章先阐述环保主义者的观点，即Tropicorp公司不做利润更高的橡胶采集而做养牛这种几年后牧场就无用的事不符合自身经济利益；接着给出经济学家的反驳理由（橡胶采集投资大、工人短缺、税收高），得出环保主义者结论可能错误的观点。第一个加粗部分是环保主义者的结论，第二个加粗部分是经济学家的结论。 选项分析
A选项：第一个支持经济学家论点的结论，第二个质疑该结论。第一个是环保者结论不是支持经济学家结论，错误。 B选项：第一个陈述经济学家论点的结论，第二个支持该结论。第一个是环保者结论，错误。 C选项：第一个支持环保主义者论点的结论，第二个陈述该结论。第二个是经济学家结论不是环保者结论，错误。 D选项：第一个陈述环保主义者论点的结论，第二个陈述经济学家论点的结论。符合推理，正确。 E选项：每个都支持经济学家论点的结论。第一个是环保者结论不支持经济学家结论，错误。
