Question

compared to the amazon river, the mississippi river is:
a. less polluted.
b. more biodiverse.
c. less traveled.
d. more industrialized.

Explanation:

The Amazon River is in a relatively less - industrialized region with vast rainforest areas. The Mississippi River is in the United States, which has a long history of industrial activities along its banks. Industrial activities can lead to more pollution (so A is wrong as it's not less polluted), and the Amazon is known for its extremely high biodiversity (so B is wrong). The Mississippi is a major transportation route (so C is wrong as it's not less traveled). Industrialization along the Mississippi has been significant compared to the Amazon.

Answer:

D. more industrialized.
