孤岛的方式真得是大道至简了！谢谢分享

楼楼好，我今天做了prep 的08-test 2 69-79 题好多题目做过，但是！我用孤岛的思维做题感觉思路清楚了不少，抛弃掉各种复杂的分类方式，我觉得那些分类方式真得不适合我，尤其是今天看到herl前辈的，感觉脑子转不过来。

不过我每题都是有认真按照步骤来，认真找孤岛，思考文本的信息为何这样排兵布阵，思考转折是怎么把孤岛中的桥给切断的，然后做得很慢，但是发现认真读是能够完全精准预测到选项的。而且也能更加清楚地说出来到底为什么是无关的，这个桥怎么搭不出来。

其实之前自己做题目的时候，有过类似的思路，但是没有这么具体想不明白，所以这样形象化之后有趣很多～

Comcorp Shipping Clerk: Last week, no shipments of building supplies were sent out on Friday. The five specially ordered shipments sent out last week were sent out on Thursday, and each of those specially ordered shipments consisted entirely of building supplies. Four shipments were sent to Truax Construction last week, none of which consisted of building supplies.
If the shipping clerk's statements are true, which of the following must also be true?

AAll of Comcorp's shipments of building supplies last week were specially ordered.
BNone of Comcorp's shipments sent on Friday of last week was sent to Truax Construction.
CNone of the shipments sent by Comcorp to Truax Construction last week was specially ordered.
DNone of Comcorp's shipments sent on Thursday of last week was sent to Truax Construction.
EAll of Comcorp's shipments of building supplies last week were sent out on Thursday.

楼楼这个题目我会觉得很绕不知道该怎么思考

很高兴你认同！尽管骚扰

可以一起讨论帮助大家

写了那么多遍，就是希望能帮助大家能看到这个大道至简的道理。生活工作中大家逻辑思维能力都不错，要不也上不了大学，还要出国留学，不要被GMAT唬住了。分类不是不可以，但重要是分类后能提炼出来，不能被埋在细节里。

学而不思则罔，思而不学则殆。只分类不思考是做不好的。
再补充一点：
我们练习做题目的是训练大脑思维。训练的东西越精简，训练的效果越好。我看除了语法有些基本的语法点需要积累之外，阅读，逻辑，语法剩下训练的都应该是一个正确的思考解题过程。逻辑分类如果不能提炼精简出来，做题训练时要求大脑训练的东西多好几倍，难度更大。相反，如果大家训练大脑细心，对题目中逻辑事物之间的关联转折等，这样训练的东西少很多。一开始慢慢琢磨，不着急，假以时日，大脑会训练出这个良好敏感的逻辑思维，再解题时就容易多了。

很多阅读，包括逻辑中，不光是读懂what its saying, 更重要的是why it is saying this. 逻辑中每句话或多或少都有功能，要不是结论，要不是论据，反面顾虑，反驳反面顾虑等。逻辑上两个方向的来回推敲。在生活商业中也是常见的。一个项目方案的考核，列出考虑到的问题，然后找数据来评判这些问题的可能性。建议大家要能把其它学习工作中的逻辑思维能力运用上来。GMAT 不是一个孤立的一帮怪人故意捉弄考生，要不世界上最好的商学院哪能认可这个考试方式。它是一个考核实际逻辑思维能力，同时也会帮助大家通过备考训练这个能力。

Kitchen magazine plans to license the use of its name by a line of cookware. For a magazine, licensing the use of its name for products involves some danger, since if the products disappoint consumers, the magazine's reputation suffers, with consequent reductions in circulation and advertising. However, experts have evaluated the cookware and found it superior to all other cookware advertised in Kitchen. Therefore, Kitchen can collect its licensing fee without endangering its other revenues.

The argument above assumes which of the following?
ANo other line of cookware is superior to that which will carry the Kitchen name.
BKitchen will not license the use of its name for any products other than the line of cookware.
CMakers of cookware will not find Kitchen a less attractive advertising vehicle because the magazine's name is associated with a competing product.
DConsumers who are not regular readers of Kitchen magazine will be attracted to the cookware by the Kitchen name.
EKitchen is one of the most prestigious cooking-related magazines.

楼楼这题目我选了 b，因为我一开始是想着要去找一个能够让已经架起来的桥更稳的答案，看到b之后觉得嗯蛮像答案的，因为题目的桥已经稳了，所以添加一个附属的premise 可以更稳。所以选了b。

看了答案之后，发现是在考虑桥能不能够架起来的问题 C 如果maker 不选择杂志的话，也就没有架桥一说了。

所以我感觉我的问题是默认桥已经架起来了，其实应该是找可以把桥拆掉的因素。对吗 233333333

Comcorp Shipping Clerk: Last week, no shipments of building supplies were sent out on Friday. The five specially ordered shipments sent out last week were sent out on Thursday, and each of those specially ordered shipments consisted entirely of building supplies. Four shipments were sent to Truax Construction last week, none of which consisted of building supplies.
If the shipping clerk's statements are true, which of the following must also be true?

A. All of Comcorp's shipments of building supplies last week were specially ordered.
B. None of Comcorp's shipments sent on Friday of last week was sent to Truax Construction.
C. None of the shipments sent by Comcorp to Truax Construction last week was specially ordered.
D. None of Comcorp's shipments sent on Thursday of last week was sent to Truax Construction.
E. All of Comcorp's shipments of building supplies last week were sent out on Thursday.
这种题像离散数学里，各个集合，题目有时考这些逻辑集合的交集，并集或反面等。做题方法是在纸上把每个集合写清楚，然后看答案考核。

提炼：
(all) 5 special order were on Thursday and only have building supplies
4 shipment to TC, none of them has building supplies
Friday: no shipment of building supplies

看答案
A. Not necessarily，上面任何一个条件都没给这个
B. Not necessarily, 4 shipment to TC could be on Friday
C. True - only 5 special order building supplies, and they consisted entirely of building supplies. 正确
答案是C吗？

Kitchen magazine plans tolicense the use of its name by a line of cookware. For a magazine, licensingthe use of its name for products involves some danger, since if the productsdisappoint consumers, the magazine's reputation suffers, with consequentreductions in circulation and advertising. However, experts have evaluated thecookware and found it superior to all other cookware advertised in Kitchen.Therefore, Kitchen can collect its licensing fee without endangering its otherrevenues.

The argument above assumes which of the following?

A. No other line ofcookware is superior to that which will carry the Kitchen name.

B. Kitchen will not licensethe use of its name for any products other than the line of cookware.

C. Makers of cookware willnot find Kitchen a less attractive advertising vehicle because the magazine'sname is associated with a competing product.

D. Consumers who are notregular readers of Kitchen magazine will be attracted to the cookware by theKitchen name.

E. Kitchen is one of themost prestigious cooking-related magazines.

1. 读懂题，找出argument & line of argument

杂志考虑授名权给cookware。

顾虑：cookware disappoint consumers -> reductions in circulation and advertising

验证：专家说cookware superior -> 言下之意，不会reductions in circulation and advertising(消费者带来影响)

结论：可以授权收licensing fee，而且不会 endangering its other revenues.

2. 分析逻辑/找茬漏洞

细心点上面我们可以看到好几个逻辑思维上的漏洞或孤岛

1)专家说cookware superior ->反驳->cookware disappoint consumers ：漏洞：专家结论不一定反应顾客使用效果，superior 的东西不一定不会disappoint

2)不会reductions in circulation and advertising(消费者带来影响) ->不会 endangering its other revenues： other revenues 比(消费者带来影响)的advertising revenue 范围要大，有个跳跃

第一遍看题不见得会看到所有漏洞。考核答案时要细心，从答案角度回到题面里来看答案是不是一个漏洞，搭桥。

3. 答案
C 答案，指出上面2.2中假设漏洞。说杂志授名权给一家cookware, 别的cookware厂家也不会不来登广告。如果这个假设不成立，就会 endangering its otherrevenues。漏洞就在于，哪怕消费者没意见/杂志销量不降低(这些都是题干里论据支持的)，还是有别的影响会endangering its otherrevenues。
A- 无关，重复前提，专家已经认定。
B- tricky 无关。这个我明白你为什么选。避免这个错误，关键是明白辩论的中心议题。这里说的辩论框架是杂志授权给cookware。辩论中心是这样会不会降低营收。如果辩论框架是如何做帮助杂志增加收入，B 就在逻辑范围内了。
D，E - easy 无关

哦哦楼楼c 是怎么指出2.2的假设漏洞的呢？不是说cookware 方面考虑说，虽然kitchen 的名字和他们竞争者类似，但吸引力不减的，这不是在评估can collect its licensing fee 这个部分吗？without endangering its otherrevenues. 并没有评估吧
