Please Help I’ll give more if answer correctly. A Christmas carol plot

A Christmas Carol opens on a bleak, cold Christmas Eve in London, seven years after the death of Ebenezer Scrooge's business partner, Jacob Marley. Scrooge, an ageing miser, dislikes Christmas and refuses a dinner invitation from his nephew Fred—the son of Fan, Scrooge's dead sister. He turns away two men who seek a donation from him to provide food and heating for the poor and only grudgingly allows his overworked, underpaid clerk, Bob Cratchit, Christmas Day off with pay to conform to the social custom. That night Scrooge is visited at home by Marley's ghost, who wanders the Earth entwined by heavy chains and money boxes forged during a lifetime of greed and selfishness. Marley tells Scrooge that he has a single chance to avoid the same fate: he will be visited by three spirits and must listen or be cursed to carry much heavier chains of his own.

1. read the following excerpt from franklin d. roosevelt's "fireside chat 19":

on the other side of the picture, we must learn also to know that guerilla warfare against the germans in, let us say serbia or norway, us; that a successful russian offensive against the germans us; and that british successes on land or sea in any part of the world strengthen our hands.

remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.  

the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.
