How did the missouri compromise of 1820 attempt to settle the debate over the future of slavery in the growing american republican

 Maine entered the Union as a free state and Missouri entered the Union as a slave state.

Further details:

The Missouri Compromise (1820) admitted Missouri into the Union as a slave state with Maine being added as a free state at the same time, to keep the balance of slave and free states equal.  It also prohibited any future slave states north of the latitude line 36 1/2 degrees north of the equator in territories of the Louisiana Purchase, with the exception of Missouri (north of that line) being admitted as a slave state.  

in 1897, pershing became a tactical officer at west point, and that's where he was given the nickname "black jack." pershing's first name is "john," for which "jack" is a nickname, and he was a white man who commanded black troops. hence "black jack".
