A report concludes: 'Installing solar-powered pumps will eliminate greenhouse gas emissions associated with agricultural irrigation in the district.' Which finding would most weaken this conclusion?
Options:
(A) Due to zero operating costs, farmers pump twice as much water, causing water tables to drop and compelling the installation of higher-wattage diesel backup generators during cloudy spells.
(B) Solar panels require periodic dusting.
(C) Solar radiation peaks at noon.
(D) Monsoon clouds reduce solar generation for several weeks.
Answer Key:
A
Step-by-Step Solution & Explanation
If zero marginal pumping cost leads to diesel backup deployment and severe groundwater depletion, the emissions elimination claim is undermined.
