问题补充：

—Do you know the Capital Museum?

—Next Saturday.

A. when will they visit

B. when did they visit

C. when they visited

D. when they will visit

答案：

A. when will they visit

B. when did they visit

C. when they visited

(答案→)D. when they will visit

解析：根据句子的结构，本句应该是一个宾语从句。而宾语从句要用陈述句语序，故排除AB；根据答语Next Saturday可知，本句应将来时。所以本题选D。
