Question 12

To solve this, we recall geographical knowledge about rivers. The Mississippi River starts in Minnesota and flows to the Gulf of Mexico, draining many states. The Missouri River is a tributary of the Mississippi, the Ohio River has a different source and path, and the Colorado River flows to the Gulf of California. So the correct river is the Mississippi.

The United States does not have an official language at the federal level. While English is widely used, there's no legally established official language for the entire country. So the correct option is that the U.S. does not have an official language.

Answer:

d. Mississippi
