想请教大家一道prep的题目 - prep 07-61

At a recent conference on environmental threats to the NorthSea, most participating countries favored uniform controls on the quality of effluents, whether or not specific environmental damage could be attributed toa particular source of effluent. What must, of course, be shown, in order to avoid excessively restrictive controls,is that______ （prep 07 - 61)

(A) Any uniform controls that are adopted are likely to beimplemented without delay

(B) any substance to be made subject to controls can actually cause environmental damage

(C) the countries favoring uniform controls are those generatingthe largest quantities of effluents

(D) all of any given pollutant that is to be controlled actually reaches the North Sea at present

(E) environmentaldamage already inflicted on the North Sea is reversible

正选为B。本人错选了D, 也是最多人选择的错误选项, 回头看我觉得D最大的问题是在at present。

这道题我在做的时候第一反应是infer题型，回头看正选B觉得不像是must be true的结论, 像是plan-goal类型里可以达到目的的手段之一。gmatclub上看到专家说是assumption的题型, 但我也无法完全认同, 如果问题是assumption，原文的fact, premise, 和conclusion又分别是什么?

我不知道叫什么名字，是那种what do you need to evaluate before making a conclusion那种问题吧？选项B，如果all substance....can....，那么not excessive；如果some substance...do not...，那么excessive。

my 2 cents.

谢谢回复. 这个问题确实归类到evaluate argument的题型中比较好. 当时没想到是因为很少看到EA的题型用what must be shown来开头, in order to后面接一个specific plan goal 而不是evaluate/understand, 然后选项中也没有whether. 不过要是一开始就用EA的思路来解可能会较快意识到D中at present的问题.

发现一个自己做CR题时已经形成却不太好的习惯, 就是解题时会先对题型进行分类. 这个可以说是Manhattan Prep白字黑子引导下形成的, 一开始很好, 现在到后期如ron所言, 开始有负面影响. 作为前车之鉴和大家分享:
Ron on how to approach CR problems at first sight：

you shouldn't expect every CR problem to fit neatly into one of the "boxes" that correspond to chapters in the strategy guides.

those categories are a good starting point, but, ultimately, this is (just as it says) a test of critical reasoning. occasionally, they're going to throw stranger or more particular questions at you, and you'll have to deal with them by reading the literal words of the question and thinking about them.

in fact, "classifying" the questions is a sub-optimal approach in general.

your #1 approach should be "read the words of the question, and see whether you understand what the question is asking you to do." if you do, great! go answer the problem! in that case, there's no need to classify anything -- and, as you've seen here, trying to do so could even drive you off track.

classifying the problems can be a useful backup approach if you get lost in the original task, but it should not be the #1 way you approach these things.

D 的意思是，要证明一种污染物的全部都会排到北海。其实，一种污染物有一部分会排到北海就够了。语义问题
