—Do you know the 2011 Xiamen International Marathon was held?
—On January 2．
A. when it was that
B. when was it that
C. what it was that
D. what was it that

(答案→)A. when it was thatB. when was it thatC. what it was thatD. what was it that解析：考查含有强调句型的宾语从句。Know后面是宾语从句，从句要用陈述语序，排除B,D；根据On January 2，可知是询问时间，所以用when 引导，选A。

你的回答很对
