In relating to behavior, normal means ordinary. Someone who displays normal (and usually healthy) behavior like the majority of people. Abnormal behavior is just the opposite.
For example: Person A sees a poisonous snake. They get away from the snake in fear. This person has normal behavior. Person B sees the same snake. They get on the ground and play with the snake. This person has abnormal behavior.
This is very interesting. I don't remember it at all, and I should. However, I think there is an answer.
First there is Boxer's reaction. He had a very pragmatic view of what the bank notes meant. If you can't eat them, of what value are they? They seem an awful trade to him: at least the timber had use.
So he doesn't like the deal, but the pigs are the masters and no one argues with them.
It isn't D. Fredrick is a louse. He will deceive anyone if there is gain for him in it.
Napoleon really isn't deceitful in this passage. He is very vain. C is not quite right, but it maybe your best answer.
I don't see what B has to do with anything.
A historically has not been proven to be true. Tread carefully around a dictator. They can do you a great deal of damage. Mao for example did not seek approval: he demanded it and he killed millions getting that approval. Same with Stalin.
It is either A or C. A is true of Napoleon. It is not true of the worst dictators of the last century. C doesn't seem to fit, but I can't get rid of it. The answer is between those two. You are going to have to pick or choose one of the other two. I'd pick A myself, but I'd sure be holding my nose.
