Answer:
A. Both are used as major industrial highways
C. Flooding is a problem for both rivers
Explanation:
The Amazon River and the Mississippi River are both rivers that have enormous importance in the surroundings. While each river has its own specific importance, they also have some common features.
One of the major features that are common for this rivers is that both of them are used as major industrial highways. Both of these rivers are very large and deep, so ships can go through them without any problem. This has been used by the industry as the goods can easily be transported deep into the interior of the mainland, or from deep inside the mainland to be transported to the coastlines or sea.
These two large rivers also share a common problem. That problem is that they both have problems with flooding. Despite the Mississippi River being relatively well regulated and the shores protected, the sheer size of the river and its many tributaries still managed to bring in enough water so that major floods are caused. The Amazon, on the other side, is not regulated, and on top of it is the river with most water in the world, and it is located on one of the rainiest places on the planet, so when it floods it manages to flood areas tens or even hundreds of km away from the river itself.
