The best choice that adds credibility to Freedman’s statement that the immigrants believed that in America life would be better is:
It comes from an immigrant who called America the land of his dreams.
This choice is most relevant because Edward Corsi's personal experience and perspective as an immigrant—expressing wonder and hope about arriving in America—directly supports the idea that immigrants had optimistic expectations about their new life in the United States. His description reflects the aspirations and dreams many immigrants held when they arrived in America, reinforcing Freedman's statement.
