HELP ME PLZ ASAP !!
(a bit extra points)

how did Americans confront the issue of slavery and what were the results?

America has been messed up since it was "made." (I can say that...I'm an American.) I am not completely sure what side you are thinking of...but American's (Union) constantly got into fights with the Confederate side even before the Civil War. The key thing to understand though is that American's (Union) ATTEMPTED to confront the issue(s) but that somehow made it worse. Fast forward a little bit and now we are in the CW. That caused a lot of pain, anger, and bloodshed. Lincoln was the only American that went about "confronting" it the right way. Now, the results, the results are a completely different story. See, for awhile everything was better (after the war) but somehow things got bad again. (Segregation) Now almost everything is okay again. Sadly, there is still racism (not just for black people but every ethnicity.)  

the right answer is the end of world war ii

after the end of a global wwii all the nations involved, in an attempt to create an organization to maintain world peace. this agreement would work settling international disputes via negotiation and arbitration instead of leading the issues escalate to another war.

answer: the time zones used to be whatever the local authority wanted them to be. one town might have 6am whenever the sun came up and another town had 6am 10 minutes later.  

the trains had a hard time when their orders said to be at a certain point at 6am.  

6am, but who's 6am.  

the railroads got together and set the time zones more or less along the longitude lines across the country.
