What evidence can you find in the book where the legislation shows how life changed for the Jews?

They had to wear yellow stars on their person. They were not allowed to own property and had to give it to the Nazis.

Over the years, they perfected a system of obtaining lists of all the Jewish inhabitants of a particular place and making them all wear a distinguishing mark in the form of a yellow star, herding them into "ghettoes" and then loading them into crowded cattle cars and dispatching them by train to concentration camps. There, they were either worked until they died, starved to death, or gassed.
