Groundwater overdraft occurs when a. the location of the water table changes due to season b. aquifers become polluted c. the rate of use exceeds the rate of replenishment d. trees are planted

the answer is C.) the rate of use exceeds the rate of replenishment

c. the rate of use exceeds the rate of replenishment

Groundwater overdraft occurs when more water is pumped out from ground for use and quantity of  water reaches the ground table through sources like rain, irrigation is extremely low. This results in decline in volume of groundwater. Therefore, the rate of use exceeds the rate of replenishment.

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.
