Answer:
O establish context based on the continued broken promises of white politicians.
Step-by-step explanation:
King discusses Boutwell and Connor primarily to establish context by highlighting the broken promises of white politicians, particularly in regards to civil rights issues. This helps to provide background information and helps to set the stage for the rest of his argument. It also serves to establish a sense of frustration and disillusionment on the part of the African American community, which helps to build towards King's overall argument for the need for change and progress.
