Which of the following best summarizes why the missouri compromise needed to be replaced by the compromise of 1850.
a. members of congress wanted to end the question of slavery in the us
b. us wanted to sell the territory gained after the mexican american war to build railroads, and the missouri compromise prevented it.
c. congress decided that the people should be able to decide whether the territory gained in the mexican american war should be allowed to have slavery.
d. territory gained after the mexican american war was mainly below the missouri border and the us leaders believed slavery would be necessary to ensure settlement.

answer: your answer choice should be 'a.'

explanation:

a fugitive slave law was passed, requiring northerners to return runaway slaves to their owners under penalty of law. the compromise of 1850 overturned the missouri compromise and left the overall issue of slavery unsettled

biological/genetic factors means they were born or predisposed to have something. nothing can really change it, and you can't really do much to "fix" it. it isn't something learned

these are the biological factors:

adrian is relatively tall and he is on the basketball team

(adrian can't ever stop being tall or force himself to be tall. likely one or both of his parents are tall as well and they passed on the tall gene. he probably does basketball because he is tall)

the rest are environmental/cultural factors. these are things that are taught to us. for example, cynthia wasn't born saving pocket money, her family most likely taught her this (environmental factor)

hope this !
