OG2021-786
Lockeport's commercial fishing boats use gill nets, which kill many of the netted fish, including some fish of endangered species. The fishing commission has proposed requiring the use of tent nets, which do not kill fish; boat crews would then throw back fish of endangered species. Profitable commercial fishing boats in similar areas have already switched over to tent nets. The proposal can therefore be implemented without economic harm to Lockeport's commercial fishing boat operators.
Which of the following, if true, casts the most serious doubt on the argument made for the proposal?
分析A选项
分析B选项
分析C选项
分析D选项
分析E选项

Tent nets----throw back endangered
Similar already switched
A. 强制使用后commercial boat比之前少了，说明强制使用过之后还是有harm的，削弱
B. Gill nets比tent nets需要更多维修，无关比较
C. 业余钓鱼者比商船抓的endangered更多，业余跳出范畴
D. Endangered fish濒危的原因，无关
E. Endangered fish没有经济价值，无关

这几道题都想多了，应该首先考虑直接因素，而不是间接

题目逻辑：tent net放回濒危鱼+in some areas商业船仍profitable → 对经济没有损害 答案：通过A项的fewer boats in place where ... 削弱前提 profitable in some areas

偷换概念 Profit不等于no economic harm A 用了tent net后渔船变少了，很可能就是因为蒙受了损失（虽然有点脑补）

陷阱太多，一定要先identify the argument: 新法规不会对渔民带来经济损失，然后再逐一排除无关选项。不能答非所问。比如C

指出逻辑漏洞，这里一些地方更换渔网，就直接推出所以没有经济损失。而没有说更换渔网之后的结果，结果好才可以推导出没有损失。

虽然A比起其他四个选项最靠谱，但总觉得A需要脑补。

Let's not get deviated from the question: casts the most serious doubt on the argument (made for the proposal).,ie: The proposal can, therefore, be implemented without economic harm to Lockeport's commercial fishing boat operators. A)In places where the use of tent nets has been mandated, there are typically fewer commercial fishing boats in operation than there were before tent nets came into use. -->>> Boats after rules < Boats before rules ---->> There was a economic harm >>> directly weakens our conclusion C) is a clever trap that is touching the whole argument except conclusion which is to be weakened. all other options can be easily eliminated because they are irrelevant to conclusion and argument too.
