A.
If everything were replaced with I there would be some lonely and crazed people. Nobody would care about other people. There would be no reason to progress, just only to survive. I feel that If everyone became like this that the world would simply come to an end and things would cease to exist

C.
The names given to the characters are not normal. To me they seem to reflect the thought of the names. I think that these names are used to show how they are grouped

D.
I think the word would be something like individual or self. The society in the book would not like a the thought or ideal of this word being used. I think the word would be punishable by law simply because of what it means. Also the people may realize that society doesnt really have to be grouped.
