Answer:
1.Five score 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. But 100 years later, the negro still is not free. One hundred years later, the life of the negro is still sadly crippled by the manacle of segregation and the chains of discrimination.
this goes to show that they were still not treated equally
2.It would be fatal for the nation to overlook the urgency of the moment. This sweltering summer of the negro's legitimate discontent will not pass until there is an invigorating autumn of freedom and equality.Nineteen sixty-three is not an end but a beginning.
It is A. Symbol.
A metaphor is a figure of speech.
A inference is a conclusion.
Misha I believe! Hope this helps.
