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?

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

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

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.

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

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

情景：近年，欧亚ruffe鱼被引进北美五大湖，它们靠吃当地白鱼下的蛋为生，因而造成了对湖生态的威胁。为了追踪ruffe鱼的扩散，政府制造ruffe鱼的卡片。卡上有鱼的图片，说明了鱼的害处，要求钓鱼者上报所捕获的ruffe鱼。

推理：由于本题的问题问了方案，所以肯定是方案推理。
目标：追踪ruffe鱼的扩散
方案：政府制造ruffe鱼的卡片

选题方式：方案推理有三个评估方向，简而言之，即，答案选项一定和方案的内容相关。

选项分析：

A选项： ruffe鱼的鳍上有让捕鱼者不感兴趣的刺。本选项和方案无关。

B选项：ruffe鱼晚上吃饭，而五大湖的大多数钓鱼者白天钓鱼。本选项讨论的是捕鱼的难度，和ruffe鱼的卡片没有关系。

C选项：Correct. 五大湖的大多数钓鱼者对保护白鱼感兴趣，因为白鱼是高价游戏鱼。本选项建立了方案和目标的关系。属于CQ1：方案的可行性问题。

D选项：ruffe鱼只是威胁白鱼的外来生物中的其中一种。本选项讨论的是ruffe鱼的特性，没有提及方案。

E选项：钓白鱼的饵料对于ruffe鱼不具吸引力。本选项没有提及方案。
