City forester: Streets planted with broad-canopied trees are cooler on summer afternoons than streets without them, and no street in the city has been measured as cool in the afternoon unless it is planted. The market square is the hottest place we measure and has no trees at all. So planting the square is what will cool it, and the council should find the money for it.

Which one of the following, if true, most seriously weakens the forester's argument?

AThe trees the city plants in its streets come from a list chosen to tolerate compacted soils under paving, and the same list would be used in the square.

BEvery street in the city measured as cool in the afternoon is narrow enough for its own buildings to shade it for part of the day, which the wide and open square is not.

CEvery street in the city narrow enough for its own buildings to shade it for part of the day has been planted with broad-canopied trees, which the wide and open square has not.

DA broad-canopied tree in an open paved square reaches full canopy in about fifteen years, sooner than one in a street, where its roots must share room with pipes and cables.

EShoppers asked in the square said they would stay longer on summer afternoons if it had shade to sit in.
