单项选择题

Chris: Hundreds of traffic accidents annually are attributable to the poor condition of our city’s streets. The streets must therefore be repaired to save lives.
Leslie: For less than the cost of those repairs, the city could improve its mass transit system and thus dramatically reduce traffic congestion, which contributes significantly to those traffic accidents. The city cannot afford to do both, so it should improve mass transit, because reduced traffic congestion has additional advantages.
Which of the following best describes the point at issue between Chris and Leslie

A．Whether a certain problem in fact exists.

B．How a certain problem came into being.

C．Who is responsible for addressing a certain problem.

D．Whether the city has sufficient financial resources to address a certain problem.

E．(E) How the city can best address a certain problem.
