Question

which of the following is least useful in arguing that territorial expansion was motivated by a desire to spread slavery

Answer 1

The least useful in arguing that territorial expansion was motivated by a desire to spread slavery was, the slogan "Fifty-four or Fight".

The "fifty-four or fight" campaign slogan was developed by James K. Polk, a candidate from Tennessee who was hardly known to most Americans. Despite this, he was privately prepared to reach a truce rather than start a war. Additionally, Polk accepted the British proposal to divide Oregon at the 49th parallel in June 1846, preventing conflict.
