Which statement correctly explains the reasons that the compromise of 1820 and the compromise of 1850 were unsuccessful at solving the nation's issues? slave labor was such an important part of the american economy that most northern states stopped opposing slavery.

slave and abolitionist rebellions in virginia and kansas convinced most americans that slavery was not worth fighting for.

escaped slaves became voting citizens in the north and did not want their representatives to compromise with the south.

congress could not control the states' desire to make their own laws, and dependence on slavery grew in the south while opposition to it grew in the north.

explanation: we can only guess at how our actions may be perceived in the future. doing something really big like killing lots of people, saving lots of people, affecting the lives of lots of people is a sure fire way of being remembered in historical records. we can also make a difference in the history records by being a small influence on something bigger, whether that is as a civil servant, scientist or artist.

of course you could argue that we all affect history just as tiny cogs in a   bigger machine.

if you mean how do people influence our opinions of things which have already happened, then simply by writing a book which looks at things form a different perspective and trying to convince people that this perspective is more accurate or truthful. people do it all the time i.e. richard the third was a terrible or was he? plenty would disagree, it's just that their views aren't the most widely known.n:
