mr. shelby, in the meantime, has still been plagued by debt. mrs. shelby offers to raise money, especially so that they can buy tom. mr. shelby becomes angry, and his wife lets the unlikely hope drop for the present. chloe then calls for mrs. shelby and asks if she could be hired out as a pastry cook in louisville in order to earn money for tom. mrs. shelby gives chloe her blessing.

question:

write a 1500-word historical investigation report. use exposition, narration, description, argumentation or some combination writing to support the main proposition. you will give this report orally.

there's many interesting events that have occurred over the course of humanity's existence. off the top of my head, you could discuss the cold war; the world wars (1 & 2); american civil rights movements; the russian or french revolutions. world war ii has ended. you are the leader of a great superpower—one of two   in the world. to keep the balance of power in your nation’s favor, you want to   gain as many allies as possible. you are particularly interested in gaining the   support of nations in africa, asia, and central and south america who do not   yet favor either superpower.   you call your advisers together to develop policies for making uncommin.

hope this !
