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?

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

B. In 1996 most Verdlanders who lived within the listening area of an RDS station already had a radio equipped to receive RDS.

C, Equipping a radio staion with RDS technology does not decrease the station's listening area.

D. In 1996 Verdlanders who did not own radios equipped to receive RDS could not receive any programming from the RDS radio stations that began broadcasting in Verdland after 1994.

E. The RDS radio stations in Verdland in 1996 did not all offer the same type of programming.

我选D，答案是A，不明白为什么。



还有一题：

The more frequently employees take time to exercise during working hours each week, the fewer sick days they take. Even employees who exercise only once a week during working hours take less sick time than those who do not exercise. Therefore, if companies stated fitness programs, the absentee rate in those companies would decrease significantly.

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

A. Employees who exercise during working hours occassionally fall asleep for short time after they exercise.

B. Employees who are frequently absent are the least likely to cooperate with or to join a fitness program.

C. Employees who exercise only once a week in their company's fitness program usually also exercise after work.

D. Employees who exercise in their company's fitness program use their working time no more productively than those who do not exercise.

E. Employees who exercise during working hours take slightly longer lunch breaks than employees who do not exercise.

我选C，为什么不对？B我同意是对的。C说之所以每星期锻炼一次都有效果，是因为那些雇员回家还锻炼，所以并不一定是锻炼项目起的作用，这就削弱了结论中说只要有锻炼项目，就能减少旷工情况。

我咋觉得上面A的解释都有问题？
A应该是新增加的radio stattion不是播送给那些之前不能收到信号的equipped RDS的用户 所以新增加的radio stations没有增加接收到program的number
再者，取非的话，增加stations 并reach到之前不能接受信号的人，那么接受的用户就会增多，是与原文相反的。所以A是正确的。

D的话乍一看也对，我当时也选错了。但是如果仔细一推敲，原文中equipped RDS用户数基本不变，D中说没有equip的就out of scope了

第一题A：
A、很少的RDS radio在信号不能覆盖的地区。原文提到了station增加了，但是RDS radio数量没有变化。所以A是一个假设。

第二题C：
C、是说下班后也健身。原文没有提到。所以不相关。

第一题的 C怎么不对?是不是取非了以后:减少了广播地区,结论照样成立:没有明显增加.
是这个原因吧?

第二题中b选项提出因果倒置，所以削弱

第一题的A排除了接受不到这个他因，是个标准的假设题答案。few people which has the radio can't be reached, in another word, it means that people with that radio could be reached.(dual-negativeness)



第二题代表了一类逻辑题，新东方称之为措施达目的，削弱就是要找该措施不能达目的的选项，显然B可以，C不可以。

没有抄错，就是这么写的，偶自己都读不懂。



还有不是问assumption嘛？死活从A中看不出和原文有什么关系，怎么当assumption啊？又不是问加强。

句子节构没看太懂,不知到LZ是不是抄错了.猜了.A说那个有R equip的人很少住在以前RDS站不能覆盖的地.

如果是的话,有可能这些人现再就能收到RDS的information了.

B. In 1996 most Verdlanders who lived within the listening area of an RDS station already had a radio equipped to receive RDS.

C, Equipping a radio staion with RDS technology does not decrease the station's listening area.
