Which of the following, if true, could present the most serious disadvantage for Northern Air in replacing its large planes with Skybuses (S)?
Playing gamble of reading q stem first helps.
I need to say: It is not advantageous to replace large planes with S
Quote:
Northern Air (NA) has dozens of flights daily into and out of Belleville Airport, which is highly congested.
NA operates on a highly congested airport (e.g Dubai/ Mumbai)
Quote:
Northern Air depends for its success on economy and quick turnaround
Its success depends on how can we enhance the maximum time the plane is in air, i.e.
reduce time spent for fueling or requires less fuel itself or reducing its maintenance.
adkikani - Right on track. Excellent!
One thought: keep an open mind about what "economy and quick turnaround time" mean.
You went straight to "maximum time in the air."
True, but not complete in terms of the content of the prompt and therefore potentially limiting.
The prompt stresses both turnaround and
economy in the sense of "thrift."
The prompt reinforces thrift by noting that fuel efficiency = fuel savings.
Turnaround and economy are not identical.

Quote:
consequently is planning to replace its large planes with Skybuses, the novel aerodynamic design of which is extremely fuel efficient. The Skybus’ fuel efficiency results in both lower fuel costs and reduced time spent refueling.
Conclusion marker: consequently.
So, NA plans to replace large planes with S (y)
because S delivers more mileage per fuel and this shall help to reduce time on the ground for the plane.
You are wise to spot markers. Again, turnaround time may depend on more than "time in the air."
Quote:
Quote:
(B) Aviation fuel is projected to decline in price over the next several years.
OK, so aviation fuel prices are reduced, so in fact it is advantageous to use S. This is opposite to what we want.
Spot on.
Quote:
Quote:
(E) The aerodynamic design of the Skybus causes turbulence behind it when taking off that forces other planes on the runway to delay their takeoffs.
Though I selected this correctly, I wasted up to a min to think what other planes are: S or large planes.
Eventually, it seems irrelevant to the scope of the argument.
Imp takeaway: S causes the delay for
other flights so we should not replace current large planes with S.
The delay of planes because of S is important, not the type of planes is causes delay to.
Let me know your thoughts.
See my answer below about E.
If you find yourself spending too much time trying to figure out WHY the POE answer is correct, stop after 10 seconds.
"Waste" your time differently. Go back to the other options.
Read carefully but decide
quickly whether you were correct to omit the option.
Watch for traps as you read carefully.
• A and B are straightforward 180 traps: direct flights and cheaper fuel would be advantageous to the airline.
• If you catch a word you didn't consider, reconsider that answer.
Hypothetical: (C) for example, could be relevant to turnaround time.
"Several" mechanics cut = fewer mechanics. Slower turnaround time for maintenance?
But wait: fewer mechanics cuts both ways (decreased salary costs, but maybe slight increase in turnaround time).
Decide: "several" implies "only a few" and thus makes this answer too ambiguous and probably irrelevant.
Reject (C) again
• (D) is out of scope. Only one word in the prompt, "success," has anything to do with D.
We know nothing about the rest of the industry. (Don't engage with content that is irrelevant.)
Look at (E) one more time. Take 5-10 seconds. Look for a word or a concept that is tied directly to the argument.
You hit upon the right phrase. You wrote, "S causes the delay to
other planes."
A slight adjustment: S causes the
delay to other
planes."
(E) may be confusing, but it mentions "delay," which is tied directly to "quick turnaround."
That connection is enough, and logically (E) is better than the other options.
(Respectively, those options are advantageous, ambiguous and irrelevant, and irrelevant.)
Nice work, especially because you forced yourself to choose the best answer that remained.
That move is really hard for most people. Keep it up!
