B. where were the girls; have been
C. where are the girls; have gone
D. where the girls were; have been
答案：
(答案→)A. where the girls are; have gone
B. where were the girls; have been
C. where are the girls; have gone
D. where the girls were; have been
解析：句意：-你能告诉我这些女孩子们在哪吗？-是的，他们去了博物馆。在第一个空中where 引导的是一个宾语从句，从句中应该用陈述语序，故可以先排除B和C；have been to 去过，表示去了又回来了；have gone to 去了，表示去了但没回来。根据句意可知选A。
