Surveys in Domorica indicate that only 10 percent of Domoricans in their twenties read a newspaper regularly, while more than half of all Domoricans over thirty read a newspaper regularly. Although Domoricans in their twenties constitute a large proportion of the population, newspaper publishers nonetheless predict that ten years from now, the percentage of Domoricans who regularly read a newspaper will probably be no lower than it is today. Which of the following, if true, provides the strongest grounds for the newspaper publishers' prediction? A.The number of Domoricans in their twenties is less than the number of Domoricans over thirty. B.The number of newspapers in Domorica has been gradually increasing over the past several decades. C.The proportion of Domoricans in their twenties who regularly read a newspaper has always been low. D.The surveys defined a regular reader of a newspaper as someone who reads a newspaper more than twice a week. E.The proportion of Domoricans who regularly read a newspaper was higher 20 years ago than it is today. 這題OA是C,但想不通為什麼"D國二十代閱報比例一直以來都很低"可以支持Support十年 後D國閱報的人口不會比現在還低的論點? 再板友麻煩幫忙解答,謝謝 -- ※ 發信站: 批踢踢實業坊(ptt.cc), 來自: 36.235.106.200 ※ 文章網址: https://www.ptt.cc/bbs/GMAT/M.1460876461.A.750.html ※ 編輯: taiyaki35 (36.235.106.200), 04/17/2016 15:01:50 ※ 編輯: taiyaki35 (118.160.10.242), 04/18/2016 07:49:56

首先文內已經前提過了30歲的人是閱讀報紙的最大群眾

20歲的是少眾閱讀報紙但是人數最多,過了10年
04/23 01:13, 2F

04/23 01:14, , 3F
20歲變30歲就會變閱讀的大眾,自然而然報紙就會上升
04/23 01:14, 3F

04/23 01:15, , 4F
答案要有一個設定就是這些20歲的人不會改變習慣,
04/23 01:15, 4F

04/23 01:15, , 5F
如果改變,那10年後的結果很不一定
04/23 01:15, 5F

試著去想這是一個SOP 20歲人數多但讀的人數最少
04/23 01:19, 6F

04/23 01:20, , 7F
30歲讀的人數最多,所以我們要保持這個連結
04/23 01:20, 7F

不能有額外可能性
04/23 01:20, 8F

04/23 01:26, , 9F
補充:這是一個小轉大的概念 要保證10年後不會比現在
04/23 01:26, 9F

04/23 01:27, , 10F
少讀報紙,假設如果20歲的人有增加閱讀數量,那十年
04/23 01:27, 10F

04/23 01:29, , 11F
後閱讀報紙的總量不一定會增加,因為那些增加量已經
04/23 01:29, 11F

04/23 01:30, , 12F
被統計過在過去的總量裡頭,所以十年後實際成長的幅
04/23 01:30, 12F

04/23 01:31, , 13F
度就不會提高,因此就可能不一定比現在高
04/23 01:31, 13F

04/23 01:33, , 14F
希望有幫助到你,我也還在學習,若有錯誤請指教
