Answer:
B it encouraged the westward movement of the American people
Step-by-step explanation:
what did Lewis and my boy Clark do?
they traveled westward after the louisiana purchase to explore.
it definitely didnt end conflict with natives because it seemed to be an American's destiny to kill them, it was so embedded within the culture that it was okay to wage war against these "savages".
there would be no reason for it to increase price in land that is already explored.. so answer choice C is just strange and silly.
answer choice D doesnt make sense because french werent directly involved.
answer choice B is correct
