※ 引述《cjwing (屬於我的freetime)》之銘言： : 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 : 做兩次這題都錯 : 想請牛人幫我解釋一下為何是A : 另外 若是有人對於Assumption題有些心得 : 也拜託請指導一下 : 我真的很怕assumtion題也 >.< : 寫5錯4的窘境 : 星期一就要上戰場了 : 胃痛不已阿... ---------------------分隔線------------ 其他選項為何錯我就不贅述了 題目說:(1)提供RDS PROGRAM的電台數增加 (2)有可收聽RDS PROGRAM的收音機數量幾乎一樣 (3)結論為收聽的到RDS PROGRAM的VERLAND居民可能沒有明顯增加 (A)選項說:即使有任何一個從1994年就開始在Verland廣播的RDS廣播電台, 他是廣播 給那些住在之前RDS沒有涵蓋的範圍卻有可收聽RDS PROGRAM的人, 那這些 電台也是少數 所以A選項代表說有提供RDS PROGRAM電台她所廣播的範圍沒有擴大 那(1)+(2)+上面那句話=(3)結論 那如果用取非法, 在(A)選項加個否定性副詞, 的確無法導出結論, 所以(A)對 如果再不懂, 可用實際生活的例子 無線網路當成RDS技術 可用無線網路的電腦當成RDS-equipped radio 這樣再想一想應該就可以懂哦 ^^ --
