Answer: A. establish borders between American and Spanish territories
Explanation:
The Louisiana Purchase of 1803 gave the United States vast new lands that now meant that they shared a border with New Spain. President Thomas Jefferson in a bid to find out the extent of the land that was purchased, convinced Congress to fund an expedition to establish the boundaries of the new territory.
This expedition was the Sparks' Expedition also known as the Red River Expedition. They were led by Capt. Richard Sparks of the U.S. Army and their goal was to establish positive relations with American Indians in the new territories and to establish borders between American and Spanish territories.
The Spanish were not in support of the expedition however and sent a force to stop them. The Americans then headed back in order to avoid an international incident.
The Quakers participated in the early fight for human rights in that the Quakers did not believe in the institution of slavery based on moral principles and began their fight against this unjust institution when it was still popular and largely unopposed in the United States.
