1.我认为答案是A
in that...因为 解释奥运会这个作用的原因。
when从句做状语，句意变成：当他们宣布停战协定时奥运会帮助维持和平（如果这个月没有停战协定，奥运会就没有这个作用了）

contribute to + doing/sth.
function as..
GMAT里最常出现：consider sth.sth.
consider sth or sb （to be）+adj.
consider sth. as ...也是正确的，但是不能在GMAT里用

I think the answer is B now, because C "them" is not clear, I think A is not right, because festival's is not right.
Thank you very much.
