Final answer:
Lewis and Clark are the explorers who followed the path on the map as part of their expedition from 1804 to 1806, which aimed to explore the western lands of the United States and search for potential trade routes.
Step-by-step explanation:
The explorer(s) who followed the path shown on the map to the right are Meriwether Lewis and William Clark. President Thomas Jefferson selected these two individuals to lead an expedition to explore the new western lands acquired by the United States, with a multitude of objectives including finding commercial possibilities, potential trade routes, and to solidify the United States' claim to the territory. They undertook this journey, commonly known as the Lewis and Clark Expedition, from 1804 to 1806. Despite facing numerous challenges such as fierce storms, swarms of insects, and encounters with wildlife, they traversed the West from the Mississippi to the Pacific Ocean, though they failed to find an all-water route known as the 'Northwest Passage' because none existed. Their vast contributions included mapping the territory, documenting its natural resources and wildlife, and establishing relations with Native American tribes.
