Question

这道英语题为什么选那个答案啊，要根据。

Mary wrote an article on the team___A__they had failed to win the game.
A.why B.what C.who D.that
我一开始选了D，不过答案是A，为什么呢？

Answer 1

why引导的是一个同位语从句，修饰an article，说明an article的内容，即写了一篇他们为什么没有赢得比赛的文章。

Answer 2

应该是选择A，这个句子是that引导的宾语从句，但是that是在article后面，on the team是 后面宾语从句的状语，

Answer 3

因为从why开始知道最后都是在修饰article的，也就是说这篇文章的内容是这个，其实这里是省略了that了，完整的表达应该是
Mary wrote an article on the team that why they had failed to win the game.
