Maybe character vs self???
<span>the treat that Mr.Jones will come back; Each time the animals dare to question an aspect of Napoleon’s regime, Squealer threatens them with Jones’s return. This is doubly threatening to the animals because it would mean another battle that, if lost, would result in a return to their former lifestyle of submission. Jones’s return is such a serious threat that it quashes the animals’ curiosity without fail.</span>
That they are rich and poor that means more money and less money
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)
