Final answer:
Dr. Martin Luther King Jr.'s repeated use of "now is the time" underscores the urgent need for immediate action in the civil rights movement, rejecting any form of delay in addressing racial injustices and moving towards equality and brotherhood. The correct answer among the provided options is (a) Waiting, or cooling off, is not the answer to the problem.
Step-by-step explanation:
Dr. Martin Luther King Jr.'s usage of the phrase "now is the time" in his "I Have a Dream" speech evokes a sense of immediacy and urgency in the fight for civil rights. This repetition is a rhetorical strategy that emphasizes the critical moment in history and the need for immediate action. King highlights the ongoing racial injustices and calls for a swift move towards equality, signaling that delay or inaction is no longer acceptable.
The phrase serves as a clarion call to make good on the long-overdue promises of democracy and to transition from a society riddled with segregation and racial injustice to one built on the values of brotherhood and racial justice. By insisting that the time for change is now, King rejects the notion of gradualism and insists on immediate transformation.
Among the provided options, the correct answer is (a) Waiting, or cooling off, is not the answer to the problem, which captures the thrust of King's insistence on taking urgent action against the systemic racial discrimination that plagued the United States at the time. The other options do mention issues such as broken promises and rampant injustice, but they do not specifically address the urgency conveyed through the repetition of "now is the time."
