Answer:
What is a novelist's obligation to the truth? The very word fiction implies untruth. When children read or hear a story that frightens them, they're told not to worry because “it's not true.” But for many stories to work, one has to suspend disbelief. So the essence of a novel appears to be something dishonest.
Explanation:
Here are some of the ways the families are significant, I'm not sure how far you are in the story yet tho. I read this book last year, so I can't remember which parts these are from
1) The way they have 2 children to a family, one male and one female
2) Raising children were rules in the community
3) The parents aren't the real birth givers of the children, you had to apply for kids
4) Very controlled family with special practices
Hope this helps! (I believe it's all before chapter 10)
