Here is how I usually deal with CR.
First, get familar with the common logical fallacies, such as:
- false causality (mere correlation, temporal sequence)
- false analogy ("orage and apple")
- unrepresentative statistical sample,
- tainted data of survey or poll
- time shift (all things are equal then and now or in the future)
- group-member (what's true for group is true for a memeber; vice versa)
- false condition (necessary condition, sufficient condition)
- circular reasoning ("I'm good because I'm good")
- vague or ambiguous evidence (evidence not necessarily supports conclusion)
- undefined important term
- over-stretching (making too broad a claim in scope or depth)
- assuming false exclusivity
- arguing for 2 competing objectives
etc.

Then,
- Read the question first.
- Read the stimulus, try to note the conclusion, evidences, and assumptions
- Quickly determine the line-of-reasoning and potential logical fallacy (or fallacies)
- Quick phrase your own answer to the question, if possible
- Browse the answer choices and pick the one that match yours
- If not found, re-read the question, then use the elimination technique

14. Among the more effective kinds of publicity that
publishers can get for a new book is to have excerpts
of it published in a high-circulation magazine soon
before the book is published. The benefits of such
excerption include not only a sure increase in sales
but also a fee paid by the magazine to the book's publisher.

Which of the following conclusions is best supported
by the information above?
(A) The number of people for whom seeing an
excerpt of a book in a magazine provides an
adequate substitute for reading the whole
book is smaller than the number for whom
the excerpt stimulates a desire to read the book.

如果反过来问：哪个最support以上所说，毫不犹豫就选了A，其他都不相干。

但是题目是怎么support选项A的呢？这个弯绕的忒费劲。

X: 看节选买书的人比看节选不买的人多－－－》Y: 在杂志上作节选好

如果不是X, 就不会Y，现在Y了，可见X也是对的。

在杂志上作节选好－－suppose---------既然看节选买书的人比看节选不买的人多

是这样吗？太损了。

以下是引用pacific_wei在2004-5-14 20:39:00的发言：

谢谢大家指点迷津，这是一道很混乱的题，我想了很久，想到头要炸了也看不出increse in sales 为什么能够推出 买的人大于不买的人

因为如果是50个人买50个人不买也可以认为销售增加了，我认为如果用increase in sale作为解题点，那也应该是有了excerpts之后买的人大于没有excerpts之前买的人

俺有同样的疑惑！！！

cranberry说看缩写的人原本都是想买来读的，可是题目里并没有这么说啊，如果看缩写的人本来都是不想买书的，但是看了缩写后有一部分人（即使是很小一部分）变成想买书了，这样就应该是增加销量了吧，而不需要看这样一部分人占的比例是多少，毕竟卖书不仅仅是通过在杂志上刊登摘要着一个途径啊~~

我觉得这题没有对的答案，虽然A看上去像是正确答案
