GMAT考试主要考察学生的商科思维和逻辑分析能力，目标管理题作为GMAT逻辑题中一种特殊的题型，是非常重要的。将结合具体案例为大家带来分析，关于如何提高这部分的正确率!
目标管理题主要以2种形式出现：
1、增强题：帮助目标达成
对于此类题型，在寻找正确答案时应注意：
(1)提出新观点(搭桥增强)，说明goal能够达到，或能更好地达到。
(2)排除其他plan成功的可能性(排他增强)
(3)plan百利无害
2、削弱题：阻碍目标达成
对于此类题型，在寻找正确答案时应注意：
(1)其他的plan更有可能成功(他因削弱)
(2)实施plan不会达到预期的目的(结论有误)
(3)plan有害无利
正确的解析思路
当大家在面对这两类题型时，如下：
1、确定题干目标。一般需要看文章中“in order to/ to”后面的内容是什么;
2、提取逻辑链。需要认真读取题干，对题干中提出的方案，进行简化，提取重要逻辑链信息;
3、判断逻辑题型。即判断此题目是增强还是削弱题型
下面我们一起来进行例题解读。
例题1：
Scientists are discussing ways to remove excess carbon dioxide from the atmosphere by increasing the amount that is absorbed by plant life. One plan to accomplish this is to establish giant floating seaweed farms in the oceans. When the seaweed plants die, they will be disposed of by being burned for fuel.
Which of the following, if true, would indicate the most serious weakness in the plan above?
(A) Some areas of ocean in the Southern Hemisphere do not contain
sufficient nutrients to support large seaweed farms.
(B) When a seaweed plant is burned, it releases an amount of carbon dioxide comparable to the amount it has absorbed in its lifetime.
(C) Even if seaweed farms prove effective, some people will be reluctant to switch to this new fuel.
(D) Each year about seven billion tons of carbon dioxide are released into the atmosphere but only about five billion tons are absorbed by plant life.
(E) Seaweed farms would make more money by farming seaweed to sell as nutritional supplements than by farming seaweed to sell as fuel.
解析1：
科学家讨论增加植物吸收二氧化碳来减少过量二氧化碳。一个计划是建立巨大的浮动海藻田。海藻死后，被作为燃料烧掉。
目标：减少二氧化碳
计划：建立浮动海藻田
逻辑链：浮动海藻田→吸收二氧化碳 削弱题，说明计划达不到目标。
(A) 南半球某些地区没有充足的营养支持海藻田 (some 无意义概率，与逻辑链无关，错误)
(B) 海藻烧的时候，产生的二氧化碳和整个生命周期吸收的一样多 (即没有减少二氧化碳，削弱逻辑链，正确)
(C) 即使海藻田有效，一些人不愿换用这种新燃料 (some，无意义概率，无法判断影响多大，错误)
(D) 每年大约70亿吨二氧化碳被排入大气，但只有50亿吨被植物吸收了 (说明植物还是减少了二氧化碳，并不能削弱逻辑链，错误)
(E) 海藻田靠作为营养补充品比作为燃料更赚钱 (赚钱与逻辑链无关，错误)
例题2：
To entice customers away from competitors, Red Label supermarkets have begun offering discounts on home appliances to customers who spend $50 or more on any shopping trip to Red Label. Red Label executives claim that the discount program has been a huge success, since cash register receipts of $50 or more are up thirty percent since the beginning of the program.
Which of the following, if true, most seriously weakens the claim of the Red Label executives?
(A) Most people who switched to Red Label after the program began spend more than $50 each time they shop at Red Label.
(B) Most people whose average grocery bill is less than $50 would not be persuaded to spend more by any discount program.
(C) Most people who received discounts on home appliances through Red Label’s program will shop at Red Label after the program ends.
(D) Since the beginning of the discount program, most of the people who spend $50 or more at Red Label are people who have never before shopped there and whose average grocery bill has always been higher than $50.
(E) Almost all of the people who have begun spending $50 or more at Red Label since the discount program began are longtime customers who have increased the average amount of their shopping bills by making fewer trips.
解析2：
为了把顾客从竞争对手那里吸引过来，RL开始给消费满50刀的人打折。经理声称因为买超过50刀的单子增加了30%，所以计划很成功。
目标：从竞争对手那里吸引顾客
计划：满50刀就给打折
逻辑链：满50刀就给打折→超过50的购物单子多了→计划成功 削弱题，说明实际上计划没有成功。
(A) 大多数人在折扣项目开始后转向RL，每次在RL购物时花费超过50美元。(反而增强了题干逻辑，错误)
(B) 大多数食品杂货账单低于50美元的人不会因为折扣计划而花更多的钱 (但也没说这些人会去competitors那里，与逻辑链无关，错误)
(C) 即使促销结束大多数人还是会光顾RL (这还不成功吗?增强了逻辑链，错误)
(D) 那些花了50刀以上的人是之前不来光顾的和经常购买超过50刀的顾客 (还是把人吸引过来了，增强了逻辑链，正确)
(E) 自从打折计划开始以来，几乎所有在RL开始花费50美元或50美元以上的人都是长期顾客，他们通过减少旅行次数来增加购物账单的平均数量(如果bill的增长来自于老顾客，且这些人会一次多买东西而降低光顾的次数，那就无助于收益增加，所以削弱了逻辑链，正确)
GMAT目标管理题型，大家在做题的时候可根据以上做题思路完成平时的练习。祝大家早日杀G，获得心仪学院的offer!
