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 fi shing on the Great Lakes is done during daytime hours.
(C) Most people who fi sh recreationally on the Great Lakes are interested in the preservation of the lake
whitefi sh 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 fi shing for whitefi sh on the Great Lakes is not attractive to ruffe. OG30题答案C求解释

你好：不知道你有一套自己的方法吗？
我用的lawer的方法流程如下：
1：明确类型+总结出前提与结论 support型
2：前提：R吃F的卵-威胁生态-picture—Anger报告注意core：最后要追踪
3：结论：可以追踪
4：看选项(明确错误选项两种：无关和削弱）
5：A:无关不被捕食只能说明利于增多R B削弱说明人碰不见那么就报到不了 C人们热衷保护-人们就会积极报告 D R威胁wf 然后呢？无关 E 稍微有削弱不吸引就降低人们碰见R的概率从而人们报告少我觉得通过总结一定要形成自己一个系统然后通过众多题目验证！
