GMAT CR部分的题目不知道怎么？理不清当中的逻辑是怎么样的，无需过多担心，广东雷哥GMAT将罗列一些历年OG中的CR真题来为大家解析一下，应该如何掌握解题技巧！
例题一：
Many agriculturally intensive areas of the world are beginning to encounter water scarcity problems. As a result, many farmers in these areas are likely to reduce their output as the water supply they need in order to maintain production shrinks. However, one group of farmers in such a region plans to increase their production by implementing techniques for water conservation.
Which of the following, if true, would most strongly support the prediction that the group’s plan will succeed?
A. Farmers that can gain a larger share of the food market in their regions will be better positioned to control more water resources.
B. Most agricultural practices in areas with water shortages are waterintensive.
C. Other regions of the world not facing water shortages are likely to make up for the reduction in agricultural output.
D. Demand for agricultural products in the group’s region is not expected to decline.
E. More than half the water used for agriculture in the farmers’ region is lost to evaporation or leakage from irrigation channels.
例题解析：
很多农业聚集区开始碰到缺水问题。结果，为了保证生产，随着生产供水减少，很多农民可能减少产出。然而，此地区的一群农民计划采用节水技术增加产量计划题，关注目标，支持计划成功，增强目标，即依然可以增加产量
A 占更大本地食品市场份额的农民将更好的控制水资源； 跳出范畴，排除
B 大部分与水短缺相关的农业实践是耗水的；农业实践可能包括节水技术，是耗水的，削弱目标，方向反，排除
C 其他面对水短缺问题的地区可能对农业产出减少进行补贴；无关，排除
D 此组地区的农产品需求预计不会下降；与目标无关，排除
E 此地区超过一半的农业用水因为蒸发或灌溉渠道漏水损失掉了；节水技术可以使损失的水用于生产，从而增大产量，搭桥增强，正确
结论：因为缺水问题，农民的农作物产量下降，所以某一地区的农民改进储水技术问题就能增加产量。
这里的假设是改进储水技术问题就能解决缺水问题，排除了其他原因引起的缺水问题，如果能在选项中找到是因为技术问题导致的缺水，就是正确答案。
E 选项超过一半的水因为蒸发或者管道泄漏而流失蒸发，泄漏都是技术问题
这是一道增强型题目，找到结论里的假设，确保假设没有其他可能，才能使结论无懈可击
例题二：
Only a reduction of 10 percent in the number of scheduled flights using Greentown’s airport will allow the delays that are so common there to be avoided. Hevelia airstrip, 40 miles away, would, if upgraded and expanded, be an attractive alternative for fully 20 percent of the passengers using Greentown airport. Nevertheless, experts reject the claim that turning Hevelia into a full-service airport would end the chronic delays at Greentown.
Which of the following, if true, most helps to justify the experts’ position?
A. Turning Hevelia into a full-service airport would require not onl substantial construction at the airport itself, but also the construction of new access highways.
B. A second largely undeveloped airstrip close to Greentown airport would be a more attractive alternative than Hevelia for many passengers who now use Greentown.
C. Hevelia airstrip lies in a relatively undeveloped area but would, if it became a full-service airport, be a magnet for commercial and residential development.
D. If an airplane has to wait to land, the extra jet fuel required adds significantly to the airline’s costs.
E. Several airlines use Greentown as a regional hub, so that most flights landing at Greentown have many passengers who then take different flights to reach their final destinations.
例题解析：
Greentown 的机场延误很严重，在附近的Hevelia 建一个新机场就能吸引原来使用green town 机场的乘客，可是专家不同意这样，为了justify 专家，就要思考专家的顾虑是什么，且顾虑是合理的
A 选项：建新机场需要很大的工程量，没有直接说明新机场的不好
B 选项：就算别的地方比Hevelia 更有吸引力，专家还是可能会反对，专家反对的不一定是Hevelia 这个地方本身，还是新建机场这件事
C 选项：新机场带来周边的发展，那专家就会同意了，这里没有指出专家为什么不同意
D 选项：飞机延误产生了大成本，那专家应该就同意建新机场了，不符合文意
E 选项：这句话是在说greentown 的好，这样人们可能更倾向于使用这里方便的机场，这样就没有建新机场的必要了
