Question

read the excerpt from jackie robinsons letter to president eisenhower.
when you said we must have self-respect, i wondered how we could have self-respect and remain patient considering the treatment accorded to us through the years.
this excerpt contains an historical allusion to
○ civil rights activists that advocated for equal rights in the united states throughout the 20th century.
○ the discrimination and bigotry faced by black people throughout history in the united states.
○ robinson’s belief that an end to segregation is impossible to achieve in the united states.
○ robinson’s belief that president eisenhower is responsible for ending segregation in the united states.

Explanation:

The excerpt references the "treatment accorded to us through the years" where "us" refers to Black Americans. A historical allusion here points to the long-standing systemic discrimination and bigotry this group faced in U.S. history. The other options are incorrect: the excerpt does not focus on other activists, does not state segregation is impossible, and does not frame Eisenhower as solely responsible for ending segregation.

Answer:

the discrimination and bigotry faced by Black people throughout history in the United States.
