Question

Families as a whole tend to resist change and strive to preserve what is normal. True or false?

Answer 1

First of all, it's not exactly clear what is "normal" - this changes from generation to generation and for example the traditional family used to be considered "normal" but now all other kinds of families are normal too.

Second, there is typically a big generational difference between family members, so it's hard to say that they function "as  a whole"

For these reasons I don't think this statement is true.
