A new voice-recognition system can limit access to airplane [#permalink]
 23 Sep 2010, 21:22
Question Stats:
37% (01:40) correct
62% (01:10) wrong based on 1 sessions
A new voice-recognition system can limit access to airplane controls, including those required to pilot the aircraft, to those people who have been licensed to fly the aircraft. The system identifies the persons voice by analyzing not only the tone of the voice, but also characteristics such as accent, speaking speed, and volume. Even the most adept impersonators cannot duplicate all the characteristics that the system takes into consideration. Which statement can most logically be concluded from the above passage? (A) No one can fly an airplane equipped with the system solely by virtue of their skill at impersonating voices. (B) In case of a major emergency this system could lead to a terrible airplane crash and will not, for that reason, be used by major airlines. (C) This voice-recognition system is the culmination of many years and millions of dollars of research and development. (D) In the wake of 9/11, most airplanes will soon be equipped with these systems to prevent terrorist attacks. (E) Even authorized pilots can be barred from flying their own planes if something is amiss in their voice. - Give me kudos if you like this post.

I chose 'E'. But A also looks good.... So does 'E' mean the inference form the passage?

Even I chose E and was not convinced that it is incorrect. I am not against A but felt it was weaker than E. Impersonation means all the things, the accent, speed, volume etc... consider people who mimic for a living..they would try to match all such characteristics.
Well, let us see what others think of it.

I also went for E , The claim in A seems to be extreme . Had it been "Most people" rather than "No one" , I would have gone for A . We can have a possibility of sm1 impeccably impersonating the attributes of legitimate user and passing that test . In other words , what i mean is :No system can be perfect.

I went with A, but E did look tempting. However, after considering the possibility that there might be some "backdoor" for licensed pilots it did not look as good anymore. Also, A refers to planes equipped with the system while E does not. I felt A's extreme language matched up with the stimulus where it said Quote: No one can fly an airplane equipped with the system solely by virtue of their skill at impersonating voices. with Quote: Even the most adept impersonators cannot duplicate all the characteristics that the system takes into consideration.

I too fell for E but the conclusion of an argument must capture the main point of the passage and on a closer look E fails to do so.
The jist of the argument is that since the voice-recognition system identifies the persons voice by analysing his/her tone, accent, speaking speed and volume, nobody can fly the airplane just by the virtue of their skill at impersonating voices. Hence the answer should be A.
E is something that can be inferred but not concluded.

@above..
Inference need not be the main point . For main point , it is explicitly
mentioned to point out the "Main point" of the passage..

Also conclusion questions require you to find the main point of the passage which is what this question is asking you to do. The various forms this question type can take are: 1) Which of the following expresses the main conclusin of the argument? 2) Which of the following most accurately states the main point of the argument? 3) The main point of the argument is that....

IMO A
(A) No one can fly an airplane equipped with the system solely by virtue of their skill at impersonating voices.
As the tone of the argument is positive towards the new voice recognition system , i think the inference should be positive as well.
(B) In case of a major emergency this system could lead to a terrible airplane crash and will not, for that reason, be used by major airlines.
This is negative inference
(C) This voice-recognition system is the culmination of many years and millions of dollars of research and development.
Irrelevant(D) In the wake of 9/11, most airplanes will soon be equipped with these systems to prevent terrorist attacks.
Too Narrow
(E) Even authorized pilots can be barred from flying their own planes if something is amiss in their voice.
Negative inference
Please send kudos if you like my post

No, your explanation is not good enough. But after searching throughout the Internet I have not found anything better  Only the following, but it's not brilliant... (A) This matches what we wrote as the answer to the question. Keep. (B) No mention is made of emergencies. Eliminate. (C) No mention is made of the development time of this system. Only that it is new. Eliminate. (D) No mention of 9/11 is made. Eliminate. (E) This is speculative since the prompt only mentions impersonators. Eliminate. Compare Remaining Choices (A) is the only choice remaining and is correct. Choose

I eliminated B,C and D
E is very tempting and really hard to ignore it
But I picked A
I suppose Financier is quite right!

+1 for A
E is not a direct conclusion from the passage. There's not enough information from the original passage that allows us to say for sure the voice system won't recognize an authorized pilot if something happens to his voice.
