Q14:

The Eurasian ruffe, a fish species inadvertently introduced into North America’s Great Lakes in recent years, feeds on the eggs of lake whitefish, a native species, thus threatening the lakes’ natural ecosystem. To help track the ruffe’s spread, government agencies have produced wallet-sized cards about the ruffe. The cards contain pictures of the ruffe and explain the danger they pose; the cards also request anglers to report any ruffe they catch.

Which of the following, if true, would provide most support for the prediction that the

agencies’ action will have its intended effect?

A. The ruffe has spiny fins that make it unattractive as prey.

B. Ruffe generally feed at night, but most recreational fishing on the Great Lakes is done during daytime hours.

C. Most people who fish recreationally on the Great Lakes are interested in the preservation of the lake whitefish because it is a highly prized game fish.

D. The ruffe is one of several nonnative species in the Great Lakes whose existence threatens the survival of lake whitefish populations there.

E. The bait that most people use when fishing for whitefish on the Great Lakes is not attractive to ruffe.

答案给的是C，请NN们帮助分析一下！

同意A

A-->该鱼的鳍是刺状，不容易被当作猎物
是不是表示钓鱼的人容易误以为该鱼不是他们的prey，就没有抓该鱼

所以政府发卡教育钓鱼的，让大家认得出该鱼并通报，所以help track the ruffe's spread

如果是因为鳍是刺状的就不抓，那么不要说是给卡片，就是放电影估计钓鱼人也不愿意抓

这句好笑^^

不过重点不是刺吧
重点是，他不容易被当作猎物(...make it unattractive as prey)

想像一下:
大家以为该鱼是什么植物矿物无生物或垃圾，完全看不出来他是之鱼
天晓得他就是那有害的鱼啊~!!
所以政府就发卡片，登广告，and.......maybe放电影，教育民众看到该鱼要通报
于是就天下太平，一切不是都很美好吗？

我选B 因为ruffe晚上猎食 所以白天来休闲钓鱼的人根本不知道它们存在

有牌子可以提醒他们有ruffe很危险 又可以提醒他们要回报捕猎到的ruffe数量

不知道大家觉得如何

The answer should be C.  Lawyer gave nice explanations about the answer at the below link,
