Multiple Choice
Read the following scenario and answer the question below.
On a September day in 1999, folks began to notice that Lake Jackson in the panhandle region of northern Florida was shrinking. Within a few days, it was almost gone. A sinkhole had opened beneath the lake and drained it, along with all of the fish and alligators.
As aquifers lose water, their substrates can become weaker and less capable of supporting overlying strata and any human structures built upon them. In such cases, the land surface above may subside. Sometimes subsidence can occur locally and suddenly, in the form of sinkholes, areas where the ground gives way with little warning. Once the ground subsides, soil becomes compacted, losing the porosity that enabled it to hold water. Recharging a depleted aquifer may therefore become more difficult.
-You have been hired by a small town on the Florida coast to give its residents advice about avoiding further sinkholes. You tell them that ________________.
A) they should limit development and recycle wastewater
B) if they stay here, sinkholes will occur; they should move
C) they should increase groundwater pumping
D) pumping in ocean water will recharge the aquifer
E) because sinkholes are a natural occurrence, nothing they do will help
