1. What does Jeanne imagine hatred looks like? A. Heavy Stone B. A dark cloud C. A puff of smoke D. A dense fog

You can find the answer to this question in Chapter 19 -- the one entitled "Reentry."  This chapter describes what happens as the Wakatsuki family is allowed to leave the camp at Manzanar.

Papa buys a car and the family heads back to Los Angeles.  As they do that, they start to worry about what kind of a reception they will get from all the white people.  They worry that they will be hated.  Jeanne imagines that the hate would look like a "dark, amorphous cloud" that would come down on them.

So the best answer of these would be B -- a dark cloud.
