The document discusses Rosa Parks and the Montgomery Bus Boycott. It asks what the text structure is and provides evidence that it follows a chronological structure by asking about the events surrounding Rosa Parks' arrest on December 1, 1955 and the results of the Montgomery Bus Boycott on November 13, 1956. Rosa Parks was arrested for refusing to give up her seat to a white man on a bus in Montgomery, Alabama, which sparked the Montgomery Bus Boycott by the black community and ultimately led to a Supreme Court ruling declaring segregation on public buses unconstitutional.
