1.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? - AFew 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.
- BIn 1996 most Verdlanders who lived within the listening area of an RDS station already had a radio equipped to receive RDS.
- CEquipping a radio station with RDS technology does not decrease the station's listening area.
- DIn 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.
- EThe RDS radio stations in Verdland in 1996 did not all offer the same type of programming. 只能把CE排除，但是ABD不知道该怎么选。原文的重心我理解的是：Radio stations with radio data system (RDS)增加，the number of RDS-equipped radios in Verdland in1994不变，所以the number of Verdlanders receiving the special program information不会增加。但是ABD应该怎么排除
2.Some airlines allegedly reduce fares on certain routes to a level at which they lose money, in order to drive competitors off those routes. However, this method of eliminating competition cannot be profitable in the long run. Once an airline successfully implements this method, any attempt to recoup the earlier losses by charging high fares on that route for an extended period would only provide competitors with a better opportunity to undercut the airline's fares.
Which of the following, if true, most seriously weakens the argument?
A In some countries it is not illegal for a company to drive away competitors by selling a product below cost.
B Airline executives generally believe that a company that once underpriced its fares to drive away competitors is very likely to do so again if new competitors emerge.
C As part of promotions designed to attract new customers, airlines sometimes reduce their ticket prices to below an economically sustainable level.
D deciding to stop serving particular routes, most airlines shift resources to other routes rather than reduce the size of their operations.
E When airlines dramatically reduce their fares on a particular route, the total number of air passengers on that route increases greatly. 这题为什么不选E呢，B又是说的什么意思呢，我一看到B中的Airline executives想可能他的身份应该是在支持原文说的结论，就立刻排除了。 3. 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
Asome celebrities come to the Hollywood to be seen, and so might choose to sit at the tall tables if they were available
B the price of meals ordered by celebrities dining at the Hollywood compensates for the longer time, if any, they spend lingering over their meals
C a customer of the Hollywood who would choose to sit at a tall table would be an exception to the generalization about lingering
D a restaurant's customers who spend less time at their meals typically order less expensive meals than those who remain at their meals longer
E with enough tall tables to accommodate all the Hollywood's customers interested in such seating, there would be no view except of other tall tables 这道题为什么选C不选D呢，不是说选项应该选最宽泛的那一个么，原文的意思是高椅子受欢迎，逗留时间短，利润会增加，要是削弱的话就说利润不会增加。D选项是说即使逗留时间短但是你点的吃的都很便宜不就可以削弱了么，还有C应该怎么理解，C说愿意选择高凳子的是个例外关于逗留，C应该怎么理解呢 4.During the past year, Pro-Tect Insurance Company's total payouts on car-theft claims were larger than the company can afford to sustain. Pro-Tect cannot reduce the number of car-theft policies it carries, so cannot protect itself against continued large payouts that way. Therefore, Pro-Tect has decided to offer a discount to holders of car-theft policies whose cars have antitheft devices. Many policyholders will respond to the discount by installing antitheft devices, since the amount of the discount will within two years typically more than cover the cost of installation. Thus, because cars with antitheft devices are rarely stolen, Pro-Tect's plan is likely to reduce its annual payouts.
In the argument above, the two portions in boldface play which of the following roles?
A The first rules out a certain strategy for achieving a goal; the second presents the strategy that was adopted instead and whose effectiveness the argument assesses.
B The first is a judgment made in support of a certain conclusion; the second is that conclusion.
C The first has been used as a consideration to support adopting a certain strategy for achieving a goal; the second reports a decision to adopt an alternative strategy.
D The first provides evidence in favor of adopting a certain strategy for achieving a goal; the second reports a decision to pursue an alternative goal.
E The first is a consideration offered against adopting a certain strategy for achieving a goal; the second is the main conclusion that the argument is seeking to establish. C为什么不可以呢 5.Hutonian Government Official: Federal law requires truck drivers to take a long break after driving for ten hours, but truck drivers frequently do not comply. Since the public rest areas along our highways cannot accommodate all the drivers needing a break, we plan to build more rest areas to increase the rate of compliance.
Hutonian Business Representative: But if the parking lots around our businesses are considered, there are more than enough parking places.
Which of the following, if true about Hutonia, would provide a reason for persisting with the government official's plan despite the objection?
A Public parking areas are evenly distributed along the highways.
B Truck drivers are most likely not to comply with the federal law if the total time required for a trip exceeds ten hours by less than an hour.
C In comparison to public rest areas, private parking lots near highways tend to be time-consuming for drivers to reach.
D Even when rest areas are available, some truck drivers park in places, such as highway access ramps, where their trucks are likely to cause accidents.
E Some public parking areas, particularly those on heavily traveled roads, are substantially larger than others. 这道题我觉得五个选项都不正确呢，选不出来ABE可以果断排除，CD呢？原文中official说的 rest areas 和Hutonian Business Representative说的parking places还有C选项说的 private parking lots是一个意思吗，c选项当无关排除了，D选项是不是削弱了？
