Read this passage from "The American Dream."

America is essentially a dream, a dream as yet unfulfilled. It is a dream of a land where men of all races, of all nationalities and of all creeds can live together as brothers. The substance of the dream is expressed in these sublime words, words lifted to cosmic proportions: "We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable rights, that among these are life, liberty, and pursuit of happiness." This is the dream.

Based on the passage, how does the speaker provide evidence to support the idea of the American dream?

by stating that the country was founded on the idea of equality
by presenting the idea of men as brothers who live together
by stating that the country includes people from many races
by presenting the idea that words have the power to help people
