Question

review the way that john f. kennedy uses a metaphor.
let every nation know, whether it wishes us well or ill, that we shall pay any price, bear any burden, meet any hardship, support any friend, oppose any foe, to assure the survival and the success of liberty. . . .
in the long history of the world, only a few generations have been granted the role of defending freedom in its hour of maximum danger. i do not shrink from this responsibility—i welcome it. i do not believe that any of us would exchange places with any other people or any other generation. the energy, the faith, the devotion which we bring to this endeavor will light our country and all who serve it. and the glow from that fire can truly light the world.
and so, my fellow americans, ask not what your country can do for you; ask what you can do for your country.
my fellow citizens of the world, ask not what america will do for you, but what together we can do for the freedom of man.
adapted from john f. kennedy, \inaugural address\
how does this strategy help john f. kennedy encourage americans and people worldwide to work together for freedom?
it makes american listeners feel grateful for the freedoms they enjoy.
it inspires unity and enthusiasm to aid in the global struggle for freedom.
it invites listeners to distinguish between americas interests and the worlds interests.

Explanation:

1. Analyze the first option: The text focuses on encouraging action for freedom, not on making Americans feel grateful for existing freedoms. So this option is incorrect.
2. Analyze the second option: Kennedy's metaphors (like the fire lighting the country and world) and calls to action (asking what people can do for the country/world freedom) aim to inspire people globally to unite and be enthusiastic about the fight for freedom. This matches the purpose.
3. Analyze the third option: The speech emphasizes working together ("what together we can do") rather than distinguishing interests. So this option is incorrect.

Answer:

B. It inspires unity and enthusiasm to aid in the global struggle for freedom.
