In an agricultural province, farmers recently adopted an advanced drip-irrigation technology engineered to reduce water loss from evaporation and soil runoff by forty percent per acre. Over the past three years, this technology was implemented across nearly all farms in the region. However, hydrological records show that the total volume of groundwater pumped from the region's shared aquifer for agricultural use increased substantially over those same three years, even though regional rainfall levels and the total acreage of cultivated farmland remained constant.
Which of the following, if true, most helps to resolve the apparent discrepancy described above?
- AGovernment grants and agricultural subsidies covered most of the upfront purchase and installation costs of the new drip-irrigation equipment for local farmers.
- BThe newly installed drip-irrigation systems feature automated soil sensors that shut off water delivery completely during unseasonable rainfall or high humidity.
- The increased water efficiency and lower per-acre operating costs prompted many farmers to replace drought-resistant grain crops with lucrative specialty fruits that require far more water per plant.Cevap
- DA severe multi-year meteorological drought significantly decreased the total amount of precipitation received by agricultural land across the province during the three-year period.
- EAll conventional spray irrigation systems formerly utilized in the province consistently lost more than half of their distributed water to surface runoff.
Cevap
The choice explaining that lower per-acre operating costs prompted farmers to switch to more water-intensive specialty crops.
The correct statement successfully bridges the two facts by introducing a shift in agricultural crop choice. While the irrigation hardware wastes 40% less water per acre, farmers responded to the lower marginal cost and precise water delivery by planting specialty fruit crops that consume substantially more total water than the previous drought-resistant grains. This allows per-acre efficiency to improve while total water extraction simultaneously increases across identical total acreage.

Anahtar Kavram
Reconciling an efficiency rebound effect where technological efficiency gains induce behavioral changes that increase total consumption.
