Passenger boardings on trains almost doubled between 1985 and 1995, yet the actual number of trips made by passengers increased by only 38 percent over the same period. The reason for this discrepancy is that at least two boardings are counted when a passenger must take more than one train trip to get to the final destination of his or her trip.
Which of the following, if true, best helps explain why the increase in boardings exceeded the increase in the number of train passengers between 1985 and 1995?
(A) Between 1985 and 1995, the number of train stations increased dramatically.
(B) Between 1985 and 1995, the number of train lines decreased significantly.
(C) Between 1985 and 1995, the proportion of train trips requiring passengers to change trains en route to their final destinations increased significantly.
(D) The proportion of business travelers using trains increased significantly between 1985 and 1995 relative to the proportion of pleasure travelers.
(E) The average seating capacity of passenger trains increased significantly between 1985 and 1995.

(A) Between 1985 and 1995, the number of train stations increased dramatically.
If train stations increased, it doesn't necessarily mean that the train journeys for passengers were split into multiple trips. We can rule this out.
(B) Between 1985 and 1995, the number of train lines decreased significantly.
Number of train lines is not relevant in this argument.
(C) Between 1985 and 1995, the proportion of train trips requiring passengers to change trains en route to their final destinations increased significantly.
If the proportion of trips that require passengers to change trains increased during that period, it means that more number of passengers had to change trains to reach their final destination. So the number of trips counted would exceed the number of passengers boarded. This looks like the correct option.
(D) The proportion of business travelers using trains increased significantly between 1985 and 1995 relative to the proportion of pleasure travelers.
The type of passenger is irrelevant in this case.
(E) The average seating capacity of passenger trains increased significantly between 1985 and 1995.
The seating capacity of the train is irrelevant in this case.
