Major airlines will purchase many of the new aircrafts capable of carrying more than 500 passengers on transcontinental and transoceanic flights. These airlines currently rely on "hub and spoke" systems of routing, in which large planes, which can seat 400 people and are capable of transoceanic flight, fly into hubs that have runways sufficiently long to handle them. From there, passengers are dispatched to local airports on connecting flights on small planes. With takeoff and landing time slots almost completely booked at most hubs, and little new runway construction expected, airlines will want to expand the volume of passengers they can fly in a given time slot.

The argument above would be most weakened if which of the following were true?

A. The new 500 seat aircraft cost more per seat than existing aircraft
B. Air traffic control systems at most hub airports cannot handle any more flights per hour than they currently do
C. The new 500 seat aircraft require boarding times substantially longer than those of existing aircraft
D. Small passenger aircraft, capable of efficient transcontinental and transoceanic flight and able to land on short runways, have come into service
E. Transoceanic air flights are currently running at near maximum capacity

Please provide answer along with your reasoning for each option. Thanks.

IMO its D

lets look at the options:

A. The new 500 seat aircraft cost more per seat than existing aircraft
Irrelevant and out of scope. Hence out.
B. Air traffic control systems at most hub airports cannot handle any more flights per hour than they currently do
This one would look very attractive. However, this is something that is already mentioned in the argument. Read the last sentence, With takeoff and landing time slots almost completely booked at most hubs, and little new runway construction expected. Its already given that the most slots are booked. Also, as a remedy, there is a new runway being setup. So this cannot weaken the argument. Hence out.
C. The new 500 seat aircraft require boarding times substantially longer than those of existing aircraft
Irrelevant and out of scope. Hence out.
D. Small passenger aircraft, capable of efficient transcontinental and transoceanic flight and able to land on short runways, have come into service
This option weakens the argument. Our entire argument is based on the assumptions that there are no small aircrafts available that are efficient in making transcontinental and transoceanic flight. Because, if there are such aircrafts then the Airlines will buy these small aircrafts (instead of the bigger aircrafts) capable of making the flight and landing at the local airports directly. This would increase the airllines volume of passengers at a given time slot. Hold
E. Transoceanic air flights are currently running at near maximum capacity
This does not weaken the conclusion in any way. Hence out

Hence D is correct.

Hope its clear :)

There is no medium, transcontinental and transoceanic flights, to go to small air port .Hence if new flights can take more passenger in one go,then airlines can expand their business.
Pre thinking:For weaken
big fligts will not be able to land in the existing airport --
Other way passenger can directly move to local airport/local town.


A. The new 500 seat aircraft cost more per seat than existing aircraft --Cost doesn't matter..Out of scope.
B. Air traffic control systems at most hub airports cannot handle any more flights per hour than they currently do. It may tempt you.But companies will replace their old fligts .No new flights.
C. The new 500 seat aircraft require boarding times substantially longer than those of existing aircraft.It doesn't matter as company expansion is meeting.
D. Small passenger aircraft, capable of efficient transcontinental and transoceanic flight and able to land on short runways, have come into service..Yes.Thats correct.As there is other wa passenger can go directly.
E. Transoceanic air flights are currently running at near maximum capacity.Hence we need some new option.

I went with C on this one cause I thought that given that the airlines wanted to expand the volume of passengers per given time slot, then if boarding times are substantially longer, this wouldn't be possible.

Having said this, I still have doubts on C vs D as contenders
Would be happy to discuss further

Well I think the reasoning using which I eliminated C is as below:

Fact : From the stem we understand that existing 400 seater planes are capable of transoceanic flight and fly into hubs that have runways sufficiently long to handle them.
Conclusion or aim of the airlines: Airlines want to expand the volume of passengers they can fly in a given time slot.

Assumption: Within a given time slot, we do have a way to increase passengers using the new 500 seater,capable of transcontinental and transoceanic flights, and no other alternative.

We need to weaken the above assumption link.

When we look at option C i.e. The new 500 seat aircraft require boarding times substantially longer than those of existing aircraft, we do not have any idea about boarding times for existing 400 seater. Additionally, it might be the case that additional capacity of carrying 100 passenger might still help the airlines achieve the aim. In short, if an option has insufficient info then it will not weaken the conclusion most.

But looking at option D, we know that we do have an alternative to carry additional passengers within a given time slot, keeping in mind that additional runaway construction is unlikely. So this does weaken the conclusion most.

I am not an expert but hope this helps!! :-)

'Air traffic control systems at most hub airports cannot handle any more flights' is not equivalent to 'airports cannot handle any more flights'. I think you are confusing these two terms. You could add on a hundred runways but what it says is that the traffic control cannot handle any more flight. If there are 2 people working in air traffic control then they might not be able to handle the traffic no matter how many runways you add.

'But companies will replace their old fligts' -- it's not the airline companies who will replace the systems. Their willingness to expand wholly relies on the fact that other systems are the same. My point here is that if they add new planes to their fleet but the traffic control cannot manage the new flights then those airplanes will just be left idle in the hangars.

D is practical and efficient option.
If I were a airline CEO, I would have chosen small aircraft which can land on other small airports.

Never in GMAT will we see 2 contenders such that one is better than other...Its always like one weakens and the other 4 do not weaken...A think this flouts the rule and hence is not a quality Q

The conclusion: Major airlines will purchase many of the new aircrafts capable of carrying more than 500 passengers on transcontinental and transoceanic flights.

Given that all other options clearly don't look valid here is my take on C and D:

C. The new 500 seat aircraft require boarding times substantially longer than those of existing aircraft. Let's look at the line 'With takeoff and landing time slots almost completely booked at most hubs, and little new runway construction expected, airlines will want to expand the volume of passengers they can fly in a given time slot.' The words 'almost' and 'most' do not really give us a clear picture of how saturated the time slots are. eg. out of 10 hubs 7 may have their time slots almost completely booked but the remaining 3 may have enough to accomodate these new 500 seat aircraft with longer boarding times. This does not weaken the conclusion that major airlines will purchase many of the new aircrafts capable of carrying more than 500 passengers.

That being said, the argument assumes that, given the situation, the airlines will not want to consider any other option but
to expand the volume of passengers they can fly in a given time slot with the new 500 seat aircraft. There may be another option which is likely to help the airlines achieve their objectives better, weakening the statement that Major airlines will purchase many of the new aircrafts capable of carrying more than 500 passengers on transcontinental and transoceanic flights.

D. Small passenger aircraft, capable of efficient transcontinental and transoceanic flight and able to land on short runways, have come into service. This is an option which clearly is a better bet for the airlines given the current situation and hence, weakens the conclusion.


Let me know if there is a flaw in my reasoning.

D is the correct option because Small Air-crafts will not be flying to hubs, where it is impossible to add more air crafts because of already full landing and take off time slots. Instead the Small aircrafts will be flying directly to the smaller domestic airports, which is the real final destination of travellers. Thus this weakens the airlines' plan

I think D is correct because the concern here is that big planes require longer runways, and according to option D if we have a plane which is capable of efficient transcontinental and transoceanic flight and able to land on short runways. The whole problem of "Hub and Spoke" system of routing itself will not come into picture and hence airlines would not want to purchase many of the new aircrafts capable of carrying more than 500 passengers on transcontinental and transoceanic flights.
That's what i think should be logical explanation of option D. Any comments most welcome. :o

At the same time we are not provided any information on the landing and/or time requirements for the new small planes.

"Boarding times" in C insinuates that additional time will be required to accommodate these 500 person planes, and the argument premise states that take-off and landing time slots are maxed out - these three times may or may not impact each other and may or may not weaken the conclusion.

On the whole this isn't as airtight as weaken questions should be...

On second thought, as you've mentioned, hub and spoke would be removed from the equation, thereby removing the concern about times. Perhaps you're right, but I still feel that this isn't airtight.

Conclusion of the argument is -> airlines want to expand the volume of passengers they can fly in a given time slot by purchasing 500 seat aircrafts
The Reason being -> Takeoff and landing timeslots of the hubs in transoceanic flights being maxed out with no new plans for construction of runways
So, to weaken this argument we need to provide a reason not to buy the 500 seat aircrafts

A. The new 500 seat aircraft cost more per seat than existing aircraft.
->Even thought technically this is a valid reason, it doesn't refer to the points in argument to come to this conclusion. Cost is out of Scope

B. Air traffic control systems at most hub airports cannot handle any more flights per hour than they currently do.
-> In this case, having higher per capacity of aircrafts is better to serve more people. It increases the performance of both Hubs and Airlines. So, buy 500 seat Aircrafts

C. The new 500 seat aircraft require boarding times substantially longer than those of existing aircraft.
-> The hubs are only used for dispatching of customers, so boarding time doesn't play a vital role here. Buying the 500 Seated Aircrafts does not hurt

D. Small passenger aircraft, capable of efficient transcontinental and transoceanic flight and able to land on short runways, have come into service.
->In this case, better go with Small passenger aircrafts! Since they are transcontinental, the capacity of hubs doesn't matter as there is an alternate. They can land directly in local aircrafts instead of Hubs. Also, with the increase in the landing places, the volume of people they can serve should increase as well. So, don't purchase the 500 seat aircraft, but go with the small passenger aircrafts.

E. Transoceanic air flights are currently running at near maximum capacity.
-> We are talking about flights here, and not the hubs. If the flights are reaching their maximum capacity, then buy the 500 seat aircrafts

Hope this helps :)

I opted for C and it is much better than D.

there is no mention of short or long runways in the premise. Premise says there is no scope for new runway construction.
more stress is given on time slot and airport is at operating at its peak level. if boarding time is more for bigger aircraft, then it will impact the airline's operations and on-time performance and this will further delay the schedule of other airlines.

this kind of question is strange and weird.
First, to weaken a conclusion or the argument, ones should look for an option that attacks premises or the conclusion.
Secondly, even though option D is right because it gives another possibility about small planes that can cross ocean and continent, D seems to be unclear and unambiguous.
Third, the passage is too long and has too many words; the weakener turns out to be something that is not covered in the passage.

The conclusion is that the airlines want to expand the volume of passengers per slot and for that they are aiming to buy a new aircraft that can carry 500 people.
so if boarding time increase it will have no impact. If any flight is to take off at 12 am and boarding time of that flight starts at 10 pm then increasing the number of passengers wont effect on anything. simply the airline will open its boarding time an hour before like 9 pm.
Its only when small aircraft will come in competition because people might prefer such crafts as fewer people needs connecting flight to go from international airports to local ones.

Answer is D

A is out of scope as we are not concerned by the cost of seat .

B actually strengthens the argument as the airports can not handle any more flight so airlines have to increase the capacity of the exiting slots and planes.

C also strengthens the argument as the time for boarding is substantially more thus they have to increase the capacity of the planes.

D is our answer it weakens .

E also strengthens the argument .
