这句话中which指代哪个?

题目

这句话中which指代哪个?
原文:As we have seen,work has to be compared with other values like family life,which often get lost in its interest.
58.In the last paragraph,the underlined word “which” refers to _______.
A.family life B.situations
C.other values D.trends
除了单复数的问题,
比如说把句子中family life改成family lifes.那该怎样选..
为什么?)
family life 的确是修饰 other values.
但和"为什么'which'不修饰family life"有什么关系呢?
---------------------------------------------------
为什么like family life中可省略掉,which就不能修饰他了?
-------------是不是因为which只能修饰宾语?如果这样的话,要修饰familylife应该怎么办?英语总学不好,真的很痛苦啊)

答案

比如说把句子中family life改成family lifes（复数写错了）
like family life是介词短语作定语,核心词是other values
