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.

有无线电资料系统技术的无线电站广播一些特别的节目,这些节目只有那些有rds特征的收音机才能收到,才1994年到1996, rds的无线电站从250增加到600个,然而,自从安装了rds的收音机的数量没怎么增加,收到特别节目的v人,人数也不会上升

不知道为什么选a 不懂a要表达什么

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 Verdland after 1994 broadcast to people with RDS-equipped radios living in areas not previously reached by RDS stations.只有很少的开始广告在1994年之后的rds无线电站,会向人们有rds收音机的人广播,这些人住的地方不在rds频道范围------

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

(E) The RDS radio st

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.

stool 凳子

现在的好莱坞餐厅只有标准高度的桌子,然而,很多顾客是为了看那些时不时出现的好莱坞名人才来的,他们会喜欢高一点的桌子,因为这样的座位可以让他们好的看到名人,而且做这些高桌子的人不会像坐标准桌子的顾客一样待那么就,所以好莱坞如果换了这些桌子的的话,就赚大钱了

The argument is vulnerable to criticism on the grounds that it gives reason to believe that it is likely that 这个论述易受到到批评因为它给出原因去相信很可能----这题是问什么 推论还是虚弱 答案是c

(A) some 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 那些坐高桌子的好莱坞顾客会是流连忘返的例外

(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 削弱

(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

ations in Verdland in 1996 did not all offer the same type of programming.
