估狗過了, 如果有重複還請見諒! 這題是老題目了: Educational theorists have long hypothesized that an interest in culture and the arts, especially music, has a positive impact on academic performance. A recent study of high school seniors confirms this theory. A test measuring proficiency in a broad range of academic disciplines was administered to high school seniors in major cities in the northeastern United States. The average score of students who attended schools that offered classes in art history and music appreciation was significantly higher than that of students who attended schools without such cultural enrichment programs. The agrument above assumes which of the following? A. At the schools offering art history and music appreciation classes, such classes were open to underclassmen, as well as juniors and seniors. B. Enrollment in the art history and music appreciation classes was restricted to students who had previously demonstrated an interest in culture and the arts. C. Students attending schools with cultural enrichment programs, whether they participated in such a program or not, possessed a higher average level of interest in culture and the arts than did students at other schools. D. Among students attending schools offering cultural enrichment classes, those enrolled in such classes performed better on the test than did those not enrolled in such classes. E. Students attending the schools that did not offer enrichment programs had no other opportunities to develop interest in culture and the arts. 問: 答案是C還是E呢? (很多人選C.... ) 這題問的是Assumption. 我的解法如下 A 錯, 題目沒說 B 錯, 題目沒說 D 錯, 題目沒提到'選課'(enrolment)和成績的關係為什麼我覺得C錯: 本題的argument是說, 對音樂的興趣和學業成績成正比. 有提供文化藝術音樂等課程的學校, 學生的學業成績'相較於'那些沒有提供文化藝術音樂課程學校的學生來得高.(不好意思有點拗口) 我初看覺得這是一個很可能的假設, 因為對音樂文化有興趣--> 教育學家又認為對音樂文化的興趣和學業成正比--> 故這些去有提供音樂文化課程學校的學生成績較好但是總是有怪怪的地方, 從題目我們只知道凡是去有提供音樂藝術文化這類課程學校的學生, 成績較好, 但是我們不知道他們是否都有'興趣' 另外C選項結尾的...'than did students at other schools'也很可疑, 有種 out of scope的感覺. 文中學校的分類只有一個標準 - 有沒有提供藝術類課程. E 我覺得是對的, 因為排除了這個因素, 才能確保這兩群學生之間唯一的差別在於學校是否有提供藝術類課程. 也因此才能確保'學校課程'與'成績'之間的相關性. 不過E感覺又不太像是'假設'... 所以C跟E到底怎麼選呢? 不好意思解釋的很混亂啊QQ~ 邏輯真差... 還請大大們幫幫我吧~~~ -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 61.231.15.233 ※ 編輯: Metonymia 來自: 61.231.15.233 (06/11 00:17)
