I know a little about racial relation in the U.S. In the past, colored people likes slavery in some white people's opinion. Colored people can't attend some public activities. Some white people look down on colored people.In that time, white people have prejudice with other color people.
I am interested in Jackie Robinson because I know something about him and he is famous person in baseball area. I like what he said" there is a chance for you". Whatever, only if we have chance we need to do something. Jackie Robinson use the chance, he try his best to play baseball and he become the first African-American baseball player in MLB. He is one of representative person in racial relation.
By this audio, I have learned in the past the race is a so serious problem in US. Black people faced a lot of  problem in America. Sometimes, although the people have ability to do something, they can to do because they didn't have right. They can do nothing they want. They lose the right they should have. But they insist what they want, and they are going to get that they should have.
