Critical Reasoning

In an effort to reduce traffic congestion in downtown Whitmore during the morning rush-hour, the city's transportation commission constructed a new highway connecting Whitmore directly with its northern suburbs. But since the completion of the highway, traffic congestion in downtown Whitmore has actually increased during the morning rush-hour.

Which of the following, if true, would best explain the increase in traffic congestion?

A) More commuters to downtown Whitmore come from the southern suburbs than from the northern suburbs.
B) Because the new highway gives downtown Whitmore residents easy access to the northern suburbs, several new businesses have opened adjacent to the highway in the northern suburbs.
C) Many who live and work in the northern suburbs have begun to use the highway as a way to access downtown Whitmore's nightlife.
D) The convenience of the new highway has encouraged many commuters from the northern suburbs to drive to work in downtown Whitmore rather than take public transportation.
E) The majority of people who work in downtown Whitmore also live in downtown Whitmore.
