高手进阶-很值得讨论的2到GWD逻辑题

xxu7

最近在做GWD，发现很多题最后就在2个选项里面比较，但是往往正确的那个只是更贴近原文，而错误的那个其实也没错只是稍稍不那么贴近原文，下面2道我耗了很久都想不明白，大家也来试试提高很快

Last August the XT chain of gasoline stations had a temporary sales promotion in effect in the promotion , any customer who made a purchase of ten or more gallons of gasoline was entitled to a free car wash . For the month of August , XT experienced a ten percent increase in gasoline sales as compared to sales in August the previous year so evidently the promotion was successful as a means of boosting sales.

In evaluating the argument , it would be most helpful to answer which of the following ?

A.In the areas in which XT's gasoline stations operate , how did total combined gasoline sales for all gasoline stations last August compare with sales for the previous August?
B.Was the money that XT earned from the increase in gasoline sales enough to offset the cost of providing tree car washes during the promotion?
C.Were there any customers who bought ten or more gallons at an XT gasoline station during the promotion who would have or more gallons at an XT gasoline in lower quantities , but more frequently ,if the promotion had not been in effect?
D.Did XT or any or its gasoline stations have to pay other businesses to provide the car washes that customers were offered in the promotion?
E.Are XT's gasoline sales in August usually significantly higher than one twelfth of XT's annual gasoline sales ?
A。如果Yes 则说明不了是因为promotion，因为大家都提高了，如果No,则说明 确实是promotion起到作用，
B. 如果Yes 说明这个政策却是赚钱了，那不也是增强结论即promotion是成功的，反之削弱吗

Travel agents are market intermediaries who make their living by gathering, organizing,and dispensing information about travel-related services that is not readily available to most consumers through new nformation technologies, such as the internet much of this information can now be made directly available to consumers demand for the services of travel agents will be drastically reduced.

Which of the following ,if true , most seriously weakens the argument ?

A.Travel agents routinely use the internet and other new information technologies as sources for the information they obtain for their customers.
B.The amount of information available through the internet and other new information technologies is increasing faster than the capabilities of most consumers to process it
C.Many people use travel-related services, such as airlines and hotels without consulting a travel agent .
D.The people who currently use the services of travel agents are also those most likely to gain access to new information technologies
E.The internet and other new information technologies are currently used by a relatively small proportion of the population
个人认为，这个题的难点是在文章少了两个关键的连词。如果在such as the 前面加个but,在最后一句demand for the services前价格therefore估计会有更多人做对。
原文前提1：TA（travel agents）通过新TECH能收集到大部分客户收集不到的旅游信息。
2：但是这些信息现在客户可以直接得到了
结论：TA没生意了
削弱
A。TA留客户的方式 无关
B。信息总量的增速大于客户处理的能力，所以用户直接得到信息也白搭，处理不过来还是得找TA
C. 很多TV服务不找TA，加强
D. 找TA的人也很喜欢自己去找信息，但是不知道更倾向哪个，所以无法判断是否削弱
E. 我很矛盾这个选项，因为我也选的这个，只是感觉B更贴近原文，但是E为什么错我也不是很清楚，所以还是来个大牛帮忙吧？？？

第一题，
B选项无关，文章中心是sales，而该选项却在讨论（sales-costs），也就是profits，因此无关

第二题，
E选项无法排除“用户数量迅速大量增加”这种可能性，毕竟原文为demand for the services of travel agents will be drastically reduced，“will”说明的是将来情况，E没有对将来情况做出任何限定

第一题听懂了，但是第二题B选项The amount of information available through the internet and other new information technologies is increasing faster than the capabilities of most consumers to process it
不是也说得是is increasing吗 这怎么解释呢

Weaken： demand for the services of travel agents will be drastically reduced
Patrizioren说的对，E选项仅针对现状，无法判断未来的趋势，使用internet在未来增长的趋势是未知的，因此这是一个无关的选项。即使退一万步按照常理判断使用互联网的人数增加，那么对travel agency的需求还是下降的，退一万步这也是个加强选项B选项信息增长与人们处理信息的能力的差距将进一步增大，因此信息的快速增长由于人们无法及时处理而显示不出其作用，人们对travel agency的依赖仍然继续，至少不是drastically reduced
