7. GWD32-Q7B，错选A

Travel agents are market intermediaries who make their living by gather

Ing, 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 ?

1)  Travel agents routinely use the internet and other new information tech-

nologies as sources for the information they obtain for their customers .

2)  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

3)  Many people use travel-related services, such as airlines and hotels

without consulting a travel agent .

4)  The people who currently use the services of travel agents are also

those most likely to gain access to new information technologies

5)  The internet and other new information technologies are currently used

     by a relatively small proportion of the population
这道题一开始选不出来哦,大致瞄了一下后在A,E里面选,结果答案是B,想了想,B好象是对的.B是不是从证明这种方法无效去削弱

本题argument的核心是在于讨论the role of travel agents（TA）。第一层次是说TA的作用（抑或存在价值）主要是提供对大部分消费者来说无法获得的信息，然后第二层次的一个驳论说由于新科技提供了接触这些之前无法触及信息的机会，所以TA的作用被大大削弱了。

根据题目的要求——weaken，亦即选项信息要支持如下观点：TA的左右没有被削弱（或没有被大大削弱——程度上的差异也是可以接受的），换句话说，TA仍有存在的价值。

这样来看：A选项没有给出这方面的有用信息——我是要证明TA有没有用，而不是它怎么工作；E选项其实可以部分削弱题目的观点，即新科技对TA的传统职能冲击还不是非常大，但是E有缺陷——what if the small proportion using the internet is just the major group of customers for the services of TA?再看B，说信息增长的速度超过了大多数消费者的处理能力，则TA的传统职能——处理信息，就又有了用武之地。

how about (E) ?

What's wrong with (E) ?

E是无关，咋一看，BE都很像答案，但是碰到这种情况，把两个分别取非一下就看出结果了。B取非是说“互联网和新技术增长的速度没有超过人们所能处理的速度”，也就是说有多少信息人们就可以接受多少信息，那么人们的需求确实就会下降，结论是被加强的。

E取非是说“互联网和新技术没有被一小批人所掌握”，有没有被小批人掌握又能推出什么结论呢？什么都推不出来。

即使不取非，在E中也能够找出逻辑漏洞，如果总人口中的这一小批掌握了互联网和新技术技术的人恰好就是旅游机构的所有的潜在客户呢？那么根本就形不成weaken。这种选项我归类为“漏洞weaken”或“弱weaken”。

D应该是加强吧, 选B是因为AT的organizing还是有用处的?
