Q5 - A government agency publishes

[tzyc]

I guess (B) is correct because weather is something people cannot control and if it affects some airlines the rating would not be fair and it would not be objective...
But I feel it applies to (C) as well (if it allows extra time for only busy airport so it's not fair&not objective),
so what distinguishes (B) and (C)?
Thank you

Hey there,
the stimulus tells us that efficiency of the airline personnel is being measured by using the proportion of late flights.

Our job is to find the best way to invalidate the argument. What is the best way to do that? To show flights are late because of circumstances outside the employees control.

(B) does that by saying its the weathers fault.

(C) All airlines are doing it, so it doesn't invalidate our argument. Remember, its not the airports were judging, but the companies. Also we need it to say its not the employees fault, (C) also does not do that.

(A) out of scope, we dont care about travellers choice.

(D) I'm sure airline personell are being monitored by a lot of people all the time, it doesn't really help invalidate the argument though.

(E) Doesn't really matter how late is defined, as long as it's applied objectively.

Hope that helped

So I agree with the above poster's explanation of c except for the fact that the use of the word all is enough to eliminate it. Yes, they all allow extra time, but we shouldn't assume they each allow the same amt of additional time, which could throw off our ratings.

B is the better choice for the reason mentioned above in my opinion.

Totally agree! The key here is that we are looking for an "objective mesa sure" of the relative "efficiency of different airlines' personnel".

If (C) and (E) are applied to all airlines, which - according to the answer choices - they are, then no matter what this would seem to strengthen the idea that this test is objective. What would have to be seen is whether or not this test actually tests the airline's personnel.

(B) shows how this plan breaks down because the means used to evaluate the airline's personnel could actually be affected by something other than the personnel: weather.

(D) is just ridiculous because awareness has nothing to do with this and (A) is focused on the passengers but we don't really care about them.
