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 argument 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.
题目意思是说，对文化和艺术有兴趣，可以提高学业成绩。最近一项研究显示，有提供艺
术和音乐欣赏的学校同学学业分数比没有提供这些课程的学校同学来的高。
我选 (E)，但答案是 (C)。看了一下之后，我觉得 (C) 是 ok 的。但为何 (E) 错呢?
