Answer:
True
Explanation:
On their way to the Pacific ocean, Lewis and Clarke collected information on various fauna, wildlife and tribes on their journey. However, it is important to remember that the expedition wasn't good for everyone. The expedition had distrust and disdain for local Native American tribes, calling them Savages(Thomas Jefferson called Native Americans that too) and caused much tension when they interacted with Native American tribes. The expedition also spread disease that the Native American tribes had no immunity against, leading to many deaths.
