Question

this map shows the amount of groundwater (gw) in parts of pakistan. farmers in pakistan once relied on rivers and canals for their water supply, but as cities expanded and populations grew, more farmers used groundwater for their crops. when this map was made, there were no laws restricting how many wells could be built in pakistan to remove groundwater. what would be the best solution to help pakistan conserve their water supply? a. increase the number of groundwater wells in all three regions. b. build more wells in region 3, and restrict building in all other regions. c. pass laws restricting well building in region 1, but increase wells in regions 2 and 3. d. pass laws restricting all wells, with the fewest restrictions in region 1.

Explanation:

To conserve groundwater, we need to restrict well - building in regions with low groundwater (to prevent further depletion) and manage well - building in regions with more groundwater. Option C: Passing laws to restrict well - building in region 1 (likely with low groundwater) and increasing wells in regions 2 and 3 (likely with more groundwater) makes sense. Increasing wells in regions with more groundwater can meet water needs without depleting low - groundwater regions. Option A would deplete all regions. Option B's restriction in all other regions is not targeted. Option D's fewest restrictions in region 1 would deplete it.

Answer:

C. Pass laws restricting well building in region 1, but increase wells in regions 2 and 3.
