※ 引述《cjwing (属於我的freetime)》之铭言： : 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? : (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A : 做两次这题都错 : 想请牛人帮我解释一下为何是A : 另外 若是有人对於Assumption题有些心得 : 也拜托请指导一下 : 我真的很怕assumtion题也 >.< : 写5错4的窘境 : 星期一就要上战场了 : 胃痛不已阿... ---------------------分隔线------------ 其他选项为何错我就不赘述了 题目说:(1)提供RDS PROGRAM的电台数增加 (2)有可收听RDS PROGRAM的收音机数量几乎一样 (3)结论为收听的到RDS PROGRAM的VERLAND居民可能没有明显增加 (A)选项说:即使有任何一个从1994年就开始在Verland广播的RDS广播电台, 他是广播 给那些住在之前RDS没有涵盖的范围却有可收听RDS PROGRAM的人, 那这些 电台也是少数 所以A选项代表说有提供RDS PROGRAM电台她所广播的范围没有扩大 那(1)+(2)+上面那句话=(3)结论 那如果用取非法, 在(A)选项加个否定性副词, 的确无法导出结论, 所以(A)对 如果再不懂, 可用实际生活的例子 无线网路当成RDS技术 可用无线网路的电脑当成RDS-equipped radio 这样再想一想应该就可以懂哦 ^^ --
