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?

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.
分析A选项
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

B

Even when used properly, gill nets require many more repairs than do tent nets.
分析B选项
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

C

Recreational anglers in Lockeport catch more fish of endangered species than do commercial fishing boats.
分析C选项
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

D

The endangered species of fish in Lockeport's commercial fishing area did not become endangered as a result of the use of gill nets by fishing fleets.
分析D选项
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

E

The endangered species of fish caught by Lockeport's commercial fishing fleet are of no commercial value.
分析E选项
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

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）
