A study found that neighborhoods with more trees have lower average summer temperatures. City planners infer that planting trees will cool other neighborhoods. This inference is:
A) True — trees definitely lower temperatures everywhere.
B) Probably true — the evidence suggests a cooling effect from trees.
C) Insufficient data — the neighborhoods with trees might differ in many other ways.
D) False — trees have no effect on urban temperature.
