问题补充：

Mary wrote an article on the team had failed to win the game.

A. why

B. where

C. what

D. which

答案：

(答案→)A. why

B. where

C. what

D. which

解析：考查宾语从句。本题中连接副词why连接宾语从句why the team had failed to win the game作为介词On的宾语。Why在宾语从句中做原因状语。这个宾语从句的句子结构很完整，不是要what,which，这两个词在句中要做主语或者宾语。Where与句意不符。句意：Mary写了一篇文章关于为什么这支队伍没有赢得这场比赛。故A正确。
