Task 2
Directions: This task is the same as Task 1. The 5 questions or unfinished statements are numbered 41 through 45.
Fliers may want to have their tickets in hand before catching their planes, but the airline companies are doing everything they can to bring forward cost-saving ticketless flight —no paper needed, just a ticket number and a photo ID.
Anyone who buys a Northwest E-ticket through the airline's computer service by June 16 will get an award. Next time you fly, you can buy another ticket for a friend for $ 99,good anywhere in the US or Canada through February, along with the lowest ticket prices.Some airlines offer extra frequent-flier miles for the ticketless crowd. And there are rising punishments for paper lovers. American, Northwest, United, and US Airways have raised the cost for lost-ticket replacement to $ 70 from either $ 60 or $ 50 last week. The airlines insist that the increase in price is not meant to push travelers toward E-tickets but only covers the increasing cost of replacing and tracking a missing ticket.
Why is the new ticketless flight introduced？

A. It is cheaper for air travelers.
B. It helps reduce the cost for airlines.
C. It can use computer to plan air traveling.
D. It helps prevent fliers from losing their tickets.
