CR inference quesion

by vinodhinir » Wed Sep 07, 2011 9:31 am
Got this question in a practice test..
OA is C..

My take is for B..

The last sentence talks about rise in airfares,but the OA seems to talk about low air fares..
CAN someone explain



Since the deregulation of the air travel industry in the late 1970's, air fares have been relatively low and the number of passenger-miles flown has been increasing. In recent months, however, air fares have risen but the number of passenger-miles flown is still going up.

Which of the following can most reasonably be inferred from the statements above?

A)The cost of air travel does not affect the number of passenger-miles flown.

B)People are now flying to destinations that they formerly reached by train or by other modes of transportation.

C)Factors other than low air fares must be contributing to the rise in the number of passenger-miles flown.

D)Takeovers in the deregulated air travel industry have been responsible for the rise in air fares.

E)Air fares can climb even higher without causing a drop in the number of passenger-miles flown.


Thanks

initially: low air fares and #miles increasing.
now: high air fares and #miles increasing.
What can be inferred?? (means what must be true)
B) This can be the reason for #miles increasing. but we can't say that it must be the reason. maybe people need to make more frequent trips and they still use trains or other modes of transportation for normal travels.
C) #miles are increasing despite fare rise. Thus some other factor contribute.
IMO C
If my post helped you- let me know by pushing the thanks button ;)

(Partially true but this is a strong statement, may be it affects passengers are travelling less but the number of passengers has gone up)
B)People are now flying to destinations that they formerly reached by train or by other modes of transportation.
( May be or may not be true)
C)Factors other than low air fares must be contributing to the rise in the number of passenger-miles flown.
( Keep this)
D)Takeovers in the deregulated air travel industry have been responsible for the rise in air fares.

( Not relevant)E)Air fares can climb even higher without causing a drop in the number of passenger-miles flown.

( We dont know this fact stands true or not)
C
This time no looking back!!!
