Why was the alliance og Great Britain, the United States, and the Soviet Union an unusual;? How did it change over time?

d

explanation:

i think that this is the best answer, but im sorry if this is wrong

after the senate and the house passed different bills and deadlock threatened, a compromise bill was worked out with the following provisions: (1) missouri was admitted as a slave state and maine (formerly part of massachusetts).

i know number 8 is something about only using 3/5 of the slave votes.
