一道初中的英语选择题，帮帮忙
there is still _____ who said he was ______to reach the top of the mountain besdies these two people.
a.the third one, the first b.a third one ,the fist
c.the third, the first
请说明原因
参考答案:很明显B正确。除了这两个人以外，又有一个人说他是第一个登上山顶的人。
a third one指又一个，再一个。除非说 He is the third one who ...才用the，强调他是第三个。
后一个空用the修饰序数词，没有异议。
