Last year, after the number of subway riders who had had their pockets picked at Central Station had risen to an all-time high, the transit authority erected signs in Central Station telling riders to beware of pickpockets. In the year since the signs have been erected, though, riders have had their pockets picked at Central Station at a per-capita rate nearly double that before the signs were erected.
Which of the following, if true, helps to explain the discrepancy pointed out in the passage?
A. Since Central Station's major renovation, during which the signs were erected, Central Station has become much more attractive to tourists from out of town.
B. Rising gas prices and a surging downtown job market have caused the daily number of riders at Central Station nearly to double within the past year.
C. Riders walking past the new signs tend to rummage through their pockets or feel through their clothes to verify the presence of their possessions.
D. The number of individuals convicted of petty theft or grand theft for picking pockets at Central Station has decreased within the past year.
E. Most of the pickpockets' victims were riding the subway during peak travel hours, when Central Station is especially crowded.
