Digital SAT Reading and Writing Practice Question #274

A team of urban economists evaluated the impact of a state-level tax subsidy designed to encourage the purchase of electric vehicles (EVs). The subsidy was uniformly available across the state. However, the researchers hypothesized that financial incentives alone are insufficient to drive widespread EV adoption; rather, they argued that such subsidies will only catalyze significant adoption in municipalities that already possess robust public EV charging infrastructures. Data on EV Adoption (Percentage of all vehicles) City A (High Infrastructure): Year 1 (Pre-Subsidy) = 2.1%, Year 3 (Post-Subsidy) = 9.4% City B (High Infrastructure): Year 1 (Pre-Subsidy) = 3.0%, Year 3 (Post-Subsidy) = 11.2% City C (Low Infrastructure): Year 1 (Pre-Subsidy) = 1.2%, Year 3 (Post-Subsidy) = 1.8% City D (Low Infrastructure): Year 1 (Pre-Subsidy) = 2.5%, Year 3 (Post-Subsidy) = 3.2% Which choice best describes data from the table that supports the researchers' hypothesis?
