What was the long term effect of the “bleeding kansas” problem?

the antislavery and proslavery governments established separate states.
the north and south agreed to accept kansas into the union as a slave state.
the abolitionists sent enough settlers to the kansas territory to make it a free state.
the north and south became more divided over the issue of slavery.

c. is the answer : ) (you may punch me if im wrong lol)

so, based on the research i've done. the u.s. government were always on a wild goose chase just to take down castro. he then retired his trone to his brother raul in 2008 due to some health issues. so it's obvious your answer would be:

castro had no allies from which he could receive aid.

hope this and have a fantastic day!
