Question

Which of the following was the critical issue facing political parties in the late 1840s?

Answer 1

Answer:

expansion of slavery

Explanation:

I know this because of how it was technically not the fate of native Americans in the west and probably not the acquisition of Oregon and all it is left is the annexation of texas and the expansion of slavery so I dug a little deeper and figured out that the annexation of texas happened to happen in 1845 so all that is left is an expansion of slavery which happened in 1840 and was a hugely critical issue facing political parties.
