Question

初中小生问一个英语题目，各位高手帮忙~谢谢！

这个题目是：
连接各组句子，将括号中的词置于句首。
Someone spoke to her. She had been in the office for days before that happened. （She....)
我写的是：She had been in the office for days before someone spoke to her.
但是，正确答案是：She had been in the office for days before anyone spoke to her.
为什么正确答案用的是anyone而不是someone？有点不明白，为什么要用anyone？
各位学长们指导一下，谢谢！
在原剧中我没看出有疑问和否定的意思呀

Answer 1

其实句子是否定的，因为之前“没有人”和她说话。

Answer 2

因为any用于疑问句和否定句，而some用于陈述句

Answer 3

因为any用于疑问句和否定句，而some用于陈述句~
