※ 引述《Birou (十里春风不如你)》之铭言：
: 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?
: 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.
: 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?
其实如果原po一开始有先读问句，认知到这题是假设题，
并且预测出对假设题的正确思路时，就不会被E选项混淆了。
那么，什么是实战中对这题正确的处理方法呢？
1. 先读题目问句，发现是假设题。
2. 假设题有两种可能的答案：主动假设与被动假设。
(1) 主动假设：衔接断桥。
观念教学：http://dustingmat.blogspot.tw/2015/07/blog-post_22.html
约20%的假设题是走这个方向。“不一定”以否定字眼写出来。
（原po可能是以为假设的答案都要用否定字才会避开C）
如何发现是主动假设？观察点为：结论中出现其他句中没有出现的新概念。
所以这时候应该要主动留意结论中是否有其他句没有出现的概念。
这里你会发现是“an interest in culture and the arts”（有兴趣）
因此，C选项有直接将“有兴趣”连到证据中所述的“有program的学校”，
再连到“学业表现高分”。完成衔接断桥。
而E选项提到的opportunities to develop interest...非但没有衔接断桥，
反而还创造了一个新概念“opportunities”，也就是多断了一座桥：
“谁说‘有机会发展兴趣’就等于‘有兴趣’？”
