Final answer:
The Lewis and Clark expedition contributed to knowledge in geography, botany, and animal life but not modern warfare.
Step-by-step explanation:
The Lewis and Clark expedition advanced knowledge in the following areas: geography, botany, and animal life but not in the area of modern warfare. President Thomas Jefferson commissioned Meriwether Lewis and William Clark to explore the Louisiana Territory for several reasons, including to map the territory, document its natural resources, wildlife, and to establish relations with Native American tribes. The expedition, which took place from 1804 to 1806, collected hundreds of plant and animal specimens, documented Native American customs, and mapped out vast stretches of the continent. However, the expedition did not contribute to modern warfare knowledge. It was more focused on exploration, mapping, and establishing trade routes for future economic and territorial expansion of the United States.
