有些无聊,随便打几个字。argument150的逻辑是我见过最令人发指的逻辑了,可谓是argument题库242道题中的一朵奇葩。连他自己举的evidence都在反驳他的conclusion,倒让我不知该如何下手了。。。
原题如下:
The following is a letter to the editor of an environmental magazine.
"The decline in the numbers of amphibians worldwide clearly indicates the global pollution of water and air. Two studies of amphibians in Yosemite National Park in California confirm my conclusion. In 1915 there were seven species of amphibian in the park, and there were abundant number of each species. However, in 1992 there were only four species of amphibians observed in the park, and the numbers of each species were drastically reduced. The decline in Yosemite has been blamed on the introduction of trout into the park's waters, which began in 1920(trout are known to eat amphibian eggs). But the introduction of trout cannot be the real reason for the Yosemite decline because it does not explain the worldwide decline."

最后还是给出我的思路吧:先指出可能是trout减少了amphibians的数量,再说即使不是trout,也可能是除了pollution of water and air以外的factors,再退一步,即使是pollution of water and air导致了Yosemite National Park的amphibians减少,也不能说明全球的amphibians都是它导致的。如此的让步方式,是我比较喜欢的。
