GWD-29-Q1
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.
A. with the Congressional Medal of Honor, which was the nation’s highest military award, and which was long overdue in
B. with the Congressional Medal of Honor, the nation’s highest military award for long-overdue
C. the Congressional Medal of Honor, which was the nation’s highest military award, long-overdue in
D. the Congressional Medal of Honor, the nation’s highest military award for long-overdue
E. the Congressional Medal of Honor, the nation’s highest military award, in long-overdue


答案选E
可是想请教一下，D选项为啥不行呢？
理解成对于“对于他们长时期的勇敢表现的奖励” 不行吗？
D中的“reward for”不是比E选项的“reward，in”更好吗？
求牛牛赐教！！！
