A. The river flowing through the hard rock region will have a higher velocity.
B. The river flowing through the soft rock region will have a higher discharge.
C. The river flowing through the hard rock region will have a lower sediment load.
D. The river flowing through the soft rock region will have a lower velocity.

A. Increased poverty among local communities
B. Improved infrastructure in the region
C. Enhanced biodiversity in the Niger Delta
D. Increased oil production in the region
