Hillsburgh and Nansensville are two major metropolitan areas only 50 miles apart. Until recently, the only road connecting the two cities was a traffic-clogged, six-lane Interstate Highway. Six years in the making, the Metro Expressway, a four-lane road connecting the two cities, was hoped to relieve this congestion. After the first month, however, the traffic along the Interstate Highway has not improved.

Which of the following, if true, could account for the continued traffic congestion along the Interstate Highway?

A:The Metro Expressway opened up in July, a month when many of the citizens leave for vacation.

B:During the month that the Metro Expressway opened, the railway workers who service the train connecting the two cities went on strike.

C:The new expressway is made up of a high-grade asphalt that is said to wear down less over time than the asphalt on the Interstate Highway.

D:The Hillsburgh Gazette reports that police activity along the Interstate Highway has decreased since many police are now patrolling the Metro Expressway.

E:In the next five years, both cities plan on building another expressway connecting both cities.
