Question

The greatest problem facing the United States during the period of "Manifest Destiny" was Question 12 options: whether Indians would be moved to North Carolina whether states would let women vote whether slavery would expand across the United States (into newly acquired territory) whether labor unions would be allowed to form

Answer 1

One of the biggest debates during the westward expansion was whether or not the states would be slave states or free states. Side note; this debate would become pointless eventually, as Dredd v Scott ruled that it is unconstitutional to establish slave/slave free regions.
