What characteristics of the Mississippi River make it important to national trade? Select three options.
It is used for business and tourism.
It supplies water to nearby communities.
It is a migration route for many forms of wildlife.
It serves as a sewage system for nearby communities.
It flows through the United States to the Gulf of Mexico.
For national trade a migration system doesn't have anything to do with that and I've never heard the Mississippi River serving as a sewage system though it could be true.
