Task 2
This task is the same as Task 1. The 5 questions or unfinished statements are numbered 41 to 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.
To encourage people to take ticketless flights, the airlines______.

A.sell their tickets for $ 99 from June to February the following year
B.let travelers go to both the US and Canada with the same tickets
C.allow each traveler to have an extra $ 99 ticket for a friend of theirs
D.offer ticketless travelers free miles to fly in the US
