I NEED HELP ASAPPPPP

Read the following excerpt from President John F. Kennedy's 1963 Inaugural Address. Then, respond to the question that follows.

Can we forge against these enemies a grand and global alliance, North and South, East and West, that can assure a more fruitful life for all mankind? Will you join in that historic effort?

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.

In a short response of 2–3 sentences, explain how the use of rhetorical questions in the bolded lines help to advance Kennedy's appeal for the American people to unite under a new president.
