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 information 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 ?
Travel agents routinely use the internet and other new information technologies as sources for the information they obtain for their customers.
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.
Many people use travel-related services, such as airlines and hotels without consulting a travel agent .
The people who currently use the services of travel agents are also those most likely to gain access to new information technologies.
The internet and other new information technologies are currently used by a relatively small proportion of the population.
这题E为什么不对呢？我看很多解释的都没有说到重点。E不对的关键也不在于“currently”,有人凭这个说“”用现在代表将来“去反驳，但B也是“is increasing”表达的也是现在。我觉得重点是”a small proportion of the population", 这是与题目无关的，说的是population，不是consumers.
赞成这个观点。E属于比较对象错了，放大了范围。consumers只是population的一部分，在population占比少，不代表在consumers群体占比就少。比如说，整个旅游消费群体（无论用agent service还是用新技术）都是小众的，使用新技术的人占消费全体的绝大多数，但这部分人放回到整个人口范围就还是比例很低。

这题是由比较逻辑得出的因果结论。比较的是using travel agents vs. using new technologies, 差异：info not readily available vs. info directly available. 结论：consumers' demand for travel agents下降。削弱因果逻辑，找travel agents的好或者new tech的不好。B选项说的正好是new tech的劣势。E选项似乎也是说new tech的劣势，二者差异在于B是指new tech技术本身有缺陷，E是说new tech技术没问题普及度不高而已。先不纠结population和consumers的差异，单论削弱程度来说，B就比E强烈。B否定了新技术（没有存在的必要），E否定的是普及度（可以存在，仍需努力壮大）。BE区别老大了。
P: more tech info are available to people
C: demand for travel agents decreases
Choice B: 信息多了也没用，因为大家脑子根本不够process这么多信息 (like me )
Choice D: 这帮人最有可能不需要agents因为they gain access to new tech. 加强
Choice E: 现在只有少部分人用，加强论点，更多人用new tech, less demand for agents
这道题的标点符号是有问题的。所以我选 错了。Through前面应该是句号。 such as the internet后面也应该是逗号。不知道我说的对不？
已修正。谢谢指正哟~

少个句号啊
应该还是b de都存在不确定性。。。。
这题答案到底是什么啊 看cd上讨论的也很多 但是没结论
a是加强
同意楼上“田东”的观点
这题怎么会选B呢？看题目，使用旅行社与信息处理事此消彼长的负相关关系。B选项没提过旅行社的事情。且，即便提起了，搜集旅行信息需要掌握全部处理不断增长的信息的能力么？不论信息怎么增长，搜集一部分信息就可以把。感觉D选项比较合适。D选项使用旅行社与信息两个方面，两者可是是没有关系，可以是正相关关系。最能削弱。
