PART B
Both expeditions were sent out by the President Thomas Jefferson. However, while Pike's expedition was only a military party with the goal of exploring the south and west of Louisiana, Lewis and Clark's expedition was considered to be more valuable because it happened during the Age of Enlightenment. In this expedition, they met with Oto, Missouri, Yankton Sious and Arikara chiefs. Pike's expedition brought back geographical information about the portion of new Louisiana. Clark and Lewis's expedition brought back reports, scientific specimens and Indian artefacts.
PART C
The objective of Clark and Lewis's mission was to explore the unknown territory, look for a water route from the U.S to the Pacific, trade with the Natives and make sure they knew of the United States sovereignty in the area. They presented a vast variety of animals and plants to Europeans and Americans. Lewis and Clark's expedition is still important for us nowadays, since it acts as a point of reference by which we can calculate change and progress in every area from relationships with people to the environment.
The primary reason the U.S. expanded its influence in foreign countries: Economic reasons – industrialization in the late 1800s increased the need to trade with other countries. ... Sales of American goods to foreign countries were important to the workers in the U.S.
