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?

【申友解析】


正确答案:C


题干:E罗非鱼是近年来无意中引入到北美的一种淡水鱼,它们以本土生长的白鱼的鱼卵为食从而威胁到了湖泊的生态系统平衡。为了帮助追踪罗非鱼的分布,政府部门计划制作一批钱包大小的卡片。这些卡片上包括罗非鱼的图片以及它们造成的危害,这些卡片同时要求钓鱼爱好者报告它们所捕获的罗非鱼。
题目:下面哪一项,如果为真,可以对该措施能达成目的的预测提供支持。
分析:PLAN类型正向逻辑题目,考察手段是否能有效达成目的。手段是引发卡片并要求钓鱼爱好者汇报所捕获的罗非鱼,目的是追踪罗非鱼的分布情况。
选项A, 罗非鱼长着带刺的鳍,不易成为被捕食目标。跟手段和目的都无关,排除!
选项B,罗非鱼通常在晚上进食,但是大多数钓鱼爱好者在白天钓鱼,这是威胁计划成功的负向逻辑,逻辑方向相反!
选项C,大多数钓鱼爱好者希望能保护白鱼因为白鱼是一种高价值的比赛鱼种。通过引入他因支持了手段对目的的有效性,正确!
选项D,罗非鱼是多种威胁到白鱼生存的外来物种之一,与手段和目的无关,排除!
选项E,钓白鱼的鱼饵对罗非鱼并无吸引力,这是威胁到手段是否能达成目标的负向逻辑,错误!
