单项选择题
What is implied hut not directly stated in the passage is that ________.
A．young people have been the leaders in the fight against authority
B．today, jeans are no longer looked down upon
C．jeans are the typical dress of civil rights marchers
D．formerly students were not allowed to wear jeans to class
答案
参考答案：D
解析：[参考译文] 文中已暗示到但未直接指出的是[试题分析] 此题为推论题。[详细解答] 根据原文第二段最后一句“So it is natural that teenagers would defy parents and school administrators over the right to wear jeans to Class．．．” (所以很自然，年轻人会与他们的父母及学校当局斗争以争取在教室穿牛仔的权利)。由此可推知在此之前学生是不允许穿牛仔裤到学校的。而A、B和C项文中均提到。因此D为正确选项。
