Multiple choice

Which of the following, if true, best explains the discrepancy in the argument?

Directions: Answer the given question based on the following passage:

In 2010, when private airlines in Alstonia were first allowed to operate in the country, the average domestic fares were three times the average train fares to the cities connected both by air and rail network. In the immediately following years, due to the increasing number of flights, the air fares slipped till they were just twice the train fares. Since then, the domestic airfares have reached a level that is again three times the train fare for corresponding cities even though the number of domestic flights has not changed.

  1. More foreign tourists are choosing to come to Alstonia to enjoy their vacations.

  2. The boom in the economy has lead to more Alstonians taking vacations

  3. An increase in population has increased the number of passengers.

  4. Trains have not been able to keep up with the flow of passengers in the last few years.

  5. An industrial boom has lead to many top managers traveling by air often.
