Globe trade winds, such as those that blow around the Horn of Africa, tend to unexpectedly shift direction once every five years. The force of the shift in direction, and/or its accompanying change in air pressure, is strong enough to force a commercial airline jet into a downward spiral if the pilots are not prepared for it. The response of computer-controlled detection systems on commercial jet liners to unexpected changes in air pressure and direction stemming from severe weather conditions is not entirely predictable.
Which of the following can most reasonably be concluded, if the statements above are true, about computer-controlled detection systems on board commercial jets?
(A) Sometime in the next five years a plane will crash as a result of an inappropriate response to changes in air pressure or direction.
(B) A detection system’s response to a change in air pressure or direction during a severe storm may by not be entirely accurate, unless a back-up system was included for this problem.
(C) It would be impossible for the system to distinguish changes in air pressure and direction resulting from two different types of severe weather conditions.
(D) Detection system responses depend on where in the world the changes in air pressure or direction occur.
(E) The only way a plane can avoid going into a downward spiral when air pressure or direction suddenly changes is if the detection system identifies changes early enough so that the pilots have time to react.
Does anybody know OA for this.....I am not convinced with the one which I got. will post OA later

IMO, only contenders are B and E.
I will go for E. Back up plan in B seems out of scope to me.

B has one issue.
B - talks about back up system.
E - looks clearer.
