Will someone please help me with number 3?

Answer 1

Answer:

James Polk won the election against Henry Clay because of the controversily of slavery. Clay was a slave owner and waffled on the annexation. As a slave owner Clay tried to focus on not risking going into the topic of the annexation to personally.

Answer 2

In 1850, Southerners wanted to exercise the provision to create another slave state from Texas to balance the admission of California as a free state. In one of the provisions of the Compromise of 1850, Texas was instead given a payout of $10 million to give up its northern and western claims. A few years later, the Kansas-Nebraska Act repealed the Missouri Compromise and made the issue of the boundaries a moot point. Although in theory Texas could still be divided into multiple states, any possibility of carving additional states from Texas ended when the Civil War settled the question of slavery once and for all.
