890 - Logical Reasoning

Question: In 2003 an airline in United State lost more than half, on average, of the foreign passengers they had previously served each year. Researchers have alleged that this extreme drop resulted from a rise in price of tickets for international lines from $60 to $90 per 1,000 miles.
Which of the following, if feasible, offers the best prospects for alleviating the problem of the drop in passengers as the researchers assessed it?

1. Cooperating with other airlines to provide more international lines.
2. Allowing foreign passengers to pay the same as the previous international line
3. Reemphasizing the goals and mission of the airline as serving both domestic passengers and foreign passengers
4. Increasing the financial resources of the airline by raising the ticket price for domestic passengers
5. Offering superior VIP service for foreign passengers.
