Question

Which excerpt from John F. Kennedy’s “Inaugural Address” exemplifies the use of metaphor to emphasize the global threat of nuclear warfare?
A. In your hands, my fellow citizens, more than mine, will rest the final success or failure of our course. Since this country was founded, each generation of Americans has been summoned to give testimony to its national loyalty. The graves of young Americans who answered the call to service surround the globe.
B. To that world assembly of sovereign states, the United Nations, our last best hope in an age where the instruments of war have far outpaced the instruments of peace, we renew our pledge of support—to prevent it from becoming merely a forum for invective, to strengthen its shield of the new and the weak, and to enlarge the area in which its writ may run.
C. Let both sides seek to invoke the wonders of science instead of its terrors. Together let us explore the stars, conquer the deserts, eradicate disease, tap the ocean depths, and encourage the arts and commerce.
D. Finally, to those nations who would make themselves our adversary, we offer not a pledge but a request: that both sides begin anew the quest for peace, before the dark powers of destruction unleashed by science engulf all humanity in planned or r accidental self-destruction.

Answer 1

The correct option is D.

The metaphor is a figure of speech which describes someone or something in a way that is not literally true. It is used to compare two things in an implicit way.

The global threat of nuclear warfare metaphor is represented by "the dark powers of destruction unleashed by science engulf all humanity in planned or  accidental self-destruction."

The phrase "the dark powers of destruction unleashed by science" clearly stands for nuclear weapons, which were created by scientists. The case of "planned or accidental self-destruction." also refers to nuclear power events many of which occurred in the history of  the world either by accident or were programmed.
