Ecologists hypothesize that urban green spaces reduce summer city temperatures specifically through evapotranspiration from plants, rather than only by providing shade.
Which finding, if true, would most strongly support the ecologists' hypothesis?
- A
Some plants require more water than others.
- B
Many cities have planted trees along major streets in recent years.

On hot days, air temperatures over densely vegetated parks are several degrees cooler than over equally shaded parking structures with no vegetation.
- D
Urban green spaces offer recreational benefits to residents.
Explanation
A compares vegetated and shaded-but-non-vegetated areas, isolating the contribution of plants beyond shade alone. B, C, and D are tangential.
