11. (24915-!-item-!-188;#058&001837)

Radio stations with radio data system (RDS) technology broadcast special program information that only radios with an RDS feature can receive. Between 1994 and 1996, the number of RDS radio stations in Verdland increased from 250 to 600. However, since the number of RDS-equipped radios in Verdland was about the same in 1996 as in 1994, the number of Verdlanders receiving the special program information probably did not increase significantly.

Which of the following is an assumption on which the argument depends?
Station数量多了接收器不变?接受info的人数量不变

(A) Few if any of the RDS radio stations that began broadcasting in Verdland after 1994 broadcast to people with RDS-equipped radios living in areas not previously reached by RDS stations.

答案选A

但我不理解额。。。

另外还有一题哦
讲HOLLYWOODde 明星来餐厅那道

17.(26864-!-item-!-188;#058&003368)

At present the Hollywood Restaurant has only standard-height tables.However, many customers come to watch the celebrities who frequent the Hollywood

, and they would prefer tall tables with stools because such seating would afford a better view of the celebrities.Moreover, diners seated on stools typically do not stay as long as diners seated at standard-height tables.Therefore, if the Hollywood replaced some of its seating with high tables and stools, its profits would increase.

The argument is vulnerable to criticism on the grounds that it gives reason to believe that it is likely that

(C) a customer of the Hollywood who would choose to sit at a tall table would be an exception to the generalization about lingering注意，这里的generalization指的也是坐高凳子的

答案C甚是不解
我觉得a customer不能说明问题，而且文章说了坐高凳的顾客逗留的时间不必一般凳子的顾客长，但选项又说是个列外，这不是错误信息吗？

11) 此类assumption题目，取非是个好方法吧
A说，即便有，也是很少量的RDS广播站在94年以后开始对已经有收音机但是之前没信号的地方播音。
对这个假设取非，就是有大量的94年以后开始播音的电台呢，实际上这些电台是对已经有了收音机，但是之前没有信号的地方播音。则推出，V国听众数量其实是增加的，跟原文结论相反不是么？！

What choice A says is that all the newly added station after 1994 still broadcast to the same, old listeners instead of reaching out to more NEW listeners. This is the assumption required for the argument to hold.

The answer is C.

First of all, this is a paradox question and the question stem asks you to find the criticism. So let's analyze the argument.

Premises:
1) Customers come to Hollywood Restaurant to watch the celebrities so customrs would prefer tall tables to get a better view.
2) Diners seated on stools typically stay a shorter time than diners on regular seats.

Conclusion:
If the Hollywood replaced some of its seating with high tables and stools, its profits would increase.

Basically, the argument says that stools would attract more customers and customers sitting on stools turn over quickly. Therefore, profits would be up. Wait a minute. Based on premise 1, if the customers are attracted to the restaraunt because they want to see celebrities, shouldn't they stay LONGER than normal customers? If so, it runs contrary to premise 2 which describes a general trend in customer's lingering behavior. The customer attracted might sit on the stools for a LONNNNNNNNNNNNNNG time without spending much on food. No turnover, no money!

C points out this paradox and C is the correct answer.

Since this is a paradox question, the correct answer needs to point out where does the contravercy stem from. If you view D individually, it SUPPORTS the part of the argument where it says that TALLER stools will keep customers staying longer at the restaurant; but it also weakens the part of the argument where it says that the restaurant wants to increase the turnover rate. With D alone, we still do not know if the argument is weakened becasue D is a double-edged sword.

C on the other hand, points out the contraversy within the original argument like the Chinese Spear-and-Shield story.

I think this problem is not so complicated as you thought.
首先这是一道削弱题， premises和conclusion都很清楚
D选项错在不足以weaken结论，因为由于换了高桌后能够吸引更多更多的客人，多增加的这些客流量带来的利润足以弥补因为点便宜菜而带来的损失，所以利润还是会上升
C选项关键在于对generalization about lingering的理解，我认为这个指的就是premise2.因此C的意思是会选择坐在高桌的客人实际上比普通的客人呆的时间长（这很符合一般人的逻辑，所以不存在paradox；它只是文中所提及的generalization about lingering的例外而已）由于客人呆的时间长，因此返台的速度慢，（如果翻台的速度慢即使能够吸引再多的客人也没用，因为客容量在那里）会影响利润的增加，很完美的weaken了结论

以上只是个人愚见，欢迎NN拍砖~~

关于选答案的我自己理解是，文中说因为持有R的人没变所以接收到information的人不会有大的增加。注意最后一句的最后一个单词significantly
我之前选D，看到论坛上的解释是说D重复了文中的话
今天再看的时候突然发现那个few 和significantly的关系
文中只是说不会有大的增加而不是完全没有增加
所以D不对

我一开始选的D 现在终于明白了是不是说点的菜便宜不一定利润低？
还有C是说来H的人和其他地方人不一样他们坐高凳子的时间也很长
