Question

read the excerpt from martin luther king jr.s \i have a dream\ speech. fivescore years ago, a great american, in whose symbolic shadow we stand today, signed the emancipation proclamation. this momentous decree came as a great beacon light of hope to millions of negro slaves who had been seared in the flames of withering injustice. it came as a joyous daybreak to end the long night of their captivity. the emotional connotation of the underlined word helps king emphasize the documents history. significance. timing. creativity.

Explanation:

The word "momentous" means of great significance or importance. In the context of the Emancipation Proclamation, it highlights the document's far - reaching and crucial nature. It is not about just the history (as it emphasizes more than just being part of the past), not about timing (the passage doesn't focus on when it was signed in that sense), and not about creativity (there is no indication of innovative creation).

Answer:

significance.
