The historical allusions that President John F. Kennedy made in his inaugural Address were: the American Revolution
; the Discovery of America
; the Declaration of Independence. Options B, C and D are correct.
Now, I will provide somo quotes from his address with regards those allusions.
The American Revolution: "And yet, the revolutionary convictions for which our ancestors fought continue to be debated throughout the earth. Let's not forget today that we are heirs of that first revolution."
the Discovery of America: "Let us explore the stars together, conquer the deserts, extirpate the diseases, take advantage of the depths of the sea and stimulate the arts and trade."
The Declaration of Independence: "Let friends and enemies know from here and now alike, that the torch has passed into the hands of a new generation of Americans, unwilling to witness or allow the slow disintegration of human rights."
