Since the 1950s, jets have steadily replaced smaller propeller planes as the preferred method of transportation within the island nation of Kawaii. Jets are quieter and more comfortable for passengers, and can fly faster and higher. The fuel efficiency of jets has steadily improved as much as 70% since the 1950s, and travel at cruising altitude is especially efficient, as motion relies mainly on aerodynamics. However, turboprop planes are now enjoying resurgence in Kawaii, replacing jets for short trips between the islands.

Which of the following, if true, most helps to explain why turboprop planes are enjoying resurgence in Kawaii?
(A) Because trips within Kawaii are relatively short, planes spend little time at cruising altitude.
(B) As jets have become more popular, their increased price has erased the financial advantages of their fuel efficiency.
(C) Turboprop planes have also enjoyed resurgence in other island nations, especially those with extreme climates.
(D) Many of the independent airlines that once served Kawaii have been purchased by larger multinational airlines.
(E) Due to Kawaii's remote location, jet fuel is more expensive there than in most other parts of the world.

Now CR is killing me.

My take (A). Short trips =>little time at cruising altitudes => Efficiency of JETS as mentioned is not a major factor now => TP are Enjoying hence

Perhaps my brain is nor working, but I would like to know how B helps in the resurgence of the other species.
If two genres become equal, does it means that we prefer one over the other?
Moreover what is wrong with E. IMO it seems fine.
What is the OA?

@Marcab

OA is (B) indeed.

Plz advice

@Saurabh-
I too got it wrong.
It shall be great if you please post the OE.

this is a question where the source above says LSAT but I find it only on gmathack by jeff sackman

Unfortunately at the moment the website is off line (weird) and even with webchache, googlecache and so on is impossible to reach

B, anyway, is the clear answer. I do not know why you make such assumptions about E

@carcass...
I don't feel B resolves any paradox.
Does it tells us the reason why there is a resurgence of TurboProp in Kawaii? As per the paradox questions, the correct answer must support both the sides.
As per the stimulus:
i)Jets have steadily replaced smaller propeller planes as the preferred method of transportation within the island nation of Kawaii.
Then the stimulus talks about the advantages of Jets: Such as:-
a)Jets are quieter and more comfortable for passengers,
b)Jets can fly faster and higher.
c)The fuel efficiency of jets has steadily improved as much as 70% since the 1950s,
d)Jets travelling at cruising altitude is especially efficient, as motion relies mainly on aerodynamics.

Then the author counters by saying that even though Jets have so many advantages, turboprop planes are now enjoying resurgence in Kawaii, replacing jets for short trips between the islands.

Now we must find an evidence that can counter one of the advantages of the Jets. E says that in Kawaii, the Jet fuel is costlier. If Jet fuel is costlier, then the efficiency may not be that high as compared to other regions.

In B, there is elimination of just one advantage of Jets, but there are still so many advantages as listed above. Then how does B explains the resurgence?
Regards.

OE

This is an explanation question. The passage describes the various benefits of jets--their fuel efficiency, comfort, and ability to fly higher and faster than smaller planes--but then notes that turboprop planes are enjoying a resurgence. We're looking for a choice that resolves the apparent paradox.

(A) This choice addresses one of the benefits of jet travel, but it doesn't suggest why turboprop planes have overtaken jets despite the other clear advantages.
(B) This is correct. While it acknowledges the benefits of jet travel, it relates their very popularity with an increasing price that makes other alternatives more attractive.
(C) This is a common form of incorrect choice. Just because the same phenomenon is observed elsewhere does not explain why it is occurring as described in the passage.
(D) This is off-topic. It doesn't matter who owns the planes. We're looking for a choice that explains why jets are losing popularity despite several benefits.
(E) This choice suggests one cost of travel by jet, but it doesn't suggest that turboprop planes escape the same fate, nor does it confirm that the increase in cost is enough to offset the benefits of jet operation and travel.

The sourse: is valuable, without doubt

+1 for A. Because, it seems to bring in all premises.


Stated:
Since 1950's Jets have become quieter, more comfortable, faster and fly higher. FE as much as 70% (Probably stated to say it takes a LOT to negate this benefit).
Travel @ cruising altitude is especially efficient.

What if the improvements since 1950's were fine but, not actually applicable in Kawai islands case because, the trips are shorter (so passengers don't care about comfortable). Trips are shorter, so, they hardly even fly at cruising speed.

Alternatively, What if Jets can take more passengers (50-100) and turbo planes take 10-15 passengers, so, there is not more than 10 passengers per flight, so, the companies feel it is rather economic to deploy turbo planes instead of using jets almost empty. [ Nonetheless, I did not see any answers related to this]

(A) Because trips within Kawaii are relatively short, planes spend little time at cruising altitude.

This answer seems to state the same point

(B) As jets have become more popular, their increased price has erased the financial advantages of their fuel efficiency. => We've not been told of any supply/demand equation or how much is more popular and increased price? are they huge enough to negate 70% fuel efficiency. It is stretching.

(C) Turboprop planes have also enjoyed resurgence in other island nations, especially those with extreme climates.
Out of scope
(D) Many of the independent airlines that once served Kawaii have been purchased by larger multinational airlines.
No way related to the topic
(E) Due to Kawaii's remote location, jet fuel is more expensive there than in most other parts of the world.
That would have been the case always. Kawai would have not gone far away in decades. Also, we've been told 70% fuel efficiency is achieved, so, this actually doesn't resolve the paradox.
