More than fifty years after the Second World War, a number of African American soldiers were awarded―some of them posthumously―with the Congressional Medal of Honor, which was the nation’s highest military award, and which was long overdue in recognition of their outstanding bravery.

1. with the Congressional Medal of Honor, which was the nation’s highest military award, and which was long overdue in
2. with the Congressional Medal of Honor, the nation’s highest military award for long-overdue
3. the Congressional Medal of Honor, which was the nation’s highest military award, long-overdue in
4. the Congressional Medal of Honor, the nation’s highest military award for long-overdue
5. the Congressional Medal of Honor, the nation’s highest military award, in long-overdue

给的答案是E，考的人选了C

我倾向于C

不知道大家的意见！

E，窃以为：

1、award sb. sth.，with多余

2、插入语=国会勋章

3、逻辑意思：奖章给得太晚啦，而不是作定语修饰奖章。
