the death of his mother was followed two years later by the loss of his daughter

Question

是他妈先死，还是他女儿，为什么 ？

Answer 1

是他母亲先死的，两年后女儿死。
follow的意思是：如果A follow B，那就是A跟着B，改成被动语态，就是B be followed by A，由此可知，是“女儿死”跟着“母亲死”，也就是跟在这件事的后面，所以是先母后女的顺序。

Answer 2

女儿先死的，因为你他妈是followed two years later 说明是两年后

Answer 3

是他妈先死，两年后才是他女儿

举一个简单的例子：
他跟着你。
He follows you.
=You are followed by him.

Answer 4

他妈妈 翻译：他母亲去世两年后他失去了女儿

Answer 5

她女儿 was followed
