A)

Explanation:

I found the rest of your question.

A. increased water scarcity B. overfishing C. decreased soil salinity D. deforestation

Overfishing, decreased soil salinity and deforestation are concerns about agricultural production and its effect but the increased water scarcity is not.

Overfishing is considering a fish species from the water and because of that population of fish is lack which is not good.

Soil salinity can stop the plant from growing and also the quality of water.

Deforestation is the removal of forests or trees and it has a big effect on agricultural production.

a characteristic is a deep cut in the earth or left over rock aka till.  

for e2020. the answer would be some directions from the mountain range so we can find mt. whitney. to locate which direction is north, you should use a   compass. this would not only find mt. whitney, but also becuase of this long paragraph you would get points because it's not like anyone actually reads your work becuase once they read the first sentence it sounds dumb enough to not read becuase i'm not good at answering this but the answer is compass for your benefit.
