Which passage from Kennedy’s inaugural address is a metaphor? “And let every other power know that this Hemisphere intends to remain the master of its own house.” “To our sister republics south of our border, we offer a special pledge—to convert our good words into good deeds . . . .” “For only when our arms are sufficient beyond doubt can we be certain beyond doubt that they will never be employed.” “Let us never negotiate out of fear. But let us never fear to negotiate.”
