Answer :
In Martin Luther King Jr.'s "I Have a Dream" speech, the phrase that contains the strongest emotional connotations is "the long night of their captivity." This phrase evokes powerful imagery of oppression, struggle, and endurance. It highlights the historical injustices faced by African Americans and conveys a sense of perseverance and resilience in the face of adversity.
Another phrase that carries strong emotional connotations is "the Negro lives on a lonely island of poverty." This expression paints a vivid picture of isolation, deprivation, and inequality. It emphasizes the harsh realities of economic hardship and social exclusion experienced by African Americans during that time.
Both of these phrases are impactful in stirring emotions, drawing attention to the challenges and inequalities faced by African Americans, and reinforcing the urgency for social change and equality as advocated by Martin Luther King Jr. in his iconic speech.
