Many plant varieties used in industrially developed nations to improve cultivated crops come from lessdeveloped nations. No compensation is paid on the grounds that the plants used are "the common heritage of humanity." Such reasoning is, however,flawed. After all,no one suggests that coal,oil,and ores should be extracted without payment.
Which of the following best describes an aspect of the method used by the author in the argument above？
（A） The author proceeds from a number of specific observations to a tentative generalization.
（B） The author applies to the case under discussion facts about phenomena assumed to be similar in some relevant respect.
（C） A position is strengthened by showing that the opposite of that position would have logically absurd consequences.
（D） A line of reasoning is called into question on the grounds that it confuses cause and effect in a causal relation.
（E） An argument is analyzed by separating statements of fact from individual value judgments.

工业发达国家的许多用于改善庄稼的植物种类都来自于欠发达国家。他们没有付补偿金因为这些被利用的植物都是“最常见的人类的遗产”。但是，这个推理是有缺陷的。毕竟，没有人提议过煤炭，石油，和铁矿石可以不付费地提取。
注意however ，however后的句子说明付compensation是常用做法，所以不付compensation是不对的，就是c的意思

C选项是不对的，因为文中并没有提到opposite of position。说道对立面，那就应该是植物之外的所有事物，而不仅仅是植物、没有、矿石。

当初我也选C，但答案选B，我不认为答案是正确的。
因为我认为 植物+煤、石油！=全集 观点+观点=全集

而且C选项说得也很在理：
通过表明一种立场的对立面会有逻辑上可笑的结果，来加强这种立场的说明力
