The plan to increase passenger traffic at the busiest airports is high

Dinesh, we have to weaken the fact that there is not sufficient space for handling the increase in passenger and the baggage volume with the increase in the flights.

Option D clearly states that an increase in airline traffic does not correlate with an increase in passengers and baggage.

This statement is sufficient to say that this airport might fall is the category of the airports for which there is no correlation.
Hence if the volumes of baggage and passengers does not increase, so we do not need additional space.

Always remember, you need to prove all the conditions true for a statement to be true.
But to prove a statement false, you just need to prove one condition false.

Regarding option E, the additional flights in low traffic hours will still increase the overall volume of passengers and baggage.
We have no correlation with the space required to accommodate this increased volume.

Let's get this in this way

The plan to increase passenger traffic at the busiest airports is highly impractical. There is sufficient space to accommodate more take-offs and landings, but not to handle the increased volume of passengers and baggage per hour that additional flights would create.

Which of the following if true, will seriously weaken this conclusion?

A. Studies have shown that plans to increase commercial airline traffic at airports are heavily dependent on the business development plans of the airlines themselves.
B. When one of the most busiest airports increased commercial traffic by 15 percent last year, there were 10 percent more passengers per hour and 12 percent more baggage per hour.
C. If the plan to increase airline traffic is approved, the ten largest airports will serve an even higher proportion of air travellers.
D. At all airports, an increase in airline traffic does not correlate with an increase in passengers and baggage.
E. Most of the additional flights will be scheduled at times when the airport traffic is at its lowest.

Option E only states that additional flight is possible to accommodate. but we don't find any correlation of this choice with the increased or decreased number of passengers.

The argument says that additional flight will lead to increased number of passengers. So, the plan to increase passenger traffic at the busiest airports is highly impractical.

To weaken this we should find the circumstances that causal relation is not true. option D does so.

Thanks GMATIFY

now i got it....

Hi TeamGMATIFY

Kindly clarify further on option D

In my understanding you trying to saw that as the option mentions there doesn't exist any correlation among additional flight and additional baggage.

There might be a case that even if addition flights are added , even then there will not be change in the baggage quantity

CAn you further give insights of this option D

Yes, and that is what we need to show to weaken the claim that because if additional flights, baggage will also increase.
As there is not co-relation between flights and baggage, we cannot say anything. Hence D is the answer.

Does this make sense?

What is the source of this question? I found this in 800score.com and the answer is (E) over there. Even I marked (D) first, but then it showed (D) is wrong and (E) is right.

What is the source of the question? I find option E more convincing to weaken the argument.

Ans: D
My thought process is as follows:
Support :- not to handle the increased volume of passengers and baggage per hour that additional flights would create.
Conclusion:- plan to increase passenger traffic at the busiest airports is highly impractical

Pre think : What if existing flights can handle additional capacity besides current capacity.
This will make the conclusion less believable.

Option D: - it is in line with my pre think analysis.

For this question, i don't think answer D is correct. E is a better answer to this question
Let me explain how..

Premise : The plan to increase passenger traffic at the busiest airports is highly impractical.
Conclusion : There is sufficient space to accommodate more takeoffs and landings, but not to handle the increased volume of passengers and baggage per hour that additional flights would create.

It is very clear from the conclusion that the airport can easily handle the takeoffs and landings as it has space available for the operations. Conclusion also states that the airport can't handle the increased volume of passengers and baggage per hour as there is a huge rush and more passengers and baggage can't be controlled by the current equipment, manpower and space inside the airport available.

To weaken this argument we need to find an argument which says that either the increase in flights will not increase passengers and baggage volume per hour or will decrease the passenger and baggage volume per hour or somehow we are creating more space for the increased passengers and baggage which can be done if flights are introduced at the time of lowest traffic(Say afternoon or midnight).

Lets scrutiny the options one by one :

A. Studies have shown that plans to increase commercial airline traffic at airports are heavily dependent on the business development plans of the airlines themselves.
Increase commercial airline traffic dependent on business development plans of the airlines.. No relation with the passengers or baggage volume.. Out of scope.

B. When one of the most busiest airports increased commercial traffic by 15 percent last year, there were 10 percent more passengers per hour and 12 percent more baggage per hour.
Here it actually strengthens the argument that there was an increase in the volume of passengers and baggage , thought not upto the level of airline traffic increase. But there was still increase.

C. If the plan to increase airline traffic is approved, the ten largest airports will serve an even higher proportion of air travellers.
Again strengthening the argument with the 10 largest airports serving even higher proportion of air travellers, if the busiest airport is among these 10 largest airports. If the busiest airport is not one of the 10 largest airports.. then Out of scope.

D. At all airports, an increase in airline traffic does not correlate with an increase in passengers and baggage.
At all airports an increase in airline traffic doesn't correlate with an increase in passengers and baggage. But we still don't know if it will remain same, or decrease or increase.... Our option should show that it is going to be either same or decrease per hour, which is not the case with this option.

E. Most of the additional flights will be scheduled at times when the airport traffic is at its lowest.
This option says that additional flights will be scheduled at the time when the airport traffic is at its lowest .... So when per hour flights are less. Hence the increase in flight and hence the passengers and baggage volume increase can be easily taken care of.

So, according to me E is the best option and the OA should be checked again from the original source...

E. Most of the additional flights will be scheduled at times when the airport traffic is at its lowest.
This option says that additional flights will be scheduled at the time when the airport traffic is at its lowest .... So when per hour flights are less. Hence the increase in flight and hence the passengers and baggage volume increase can be easily taken care of.

We can argue in similar manner for E as well .
Even if airport traffic is at lowest , we dont know whether the excess baggage can be handled or not

Whereas D is better
At all airports, an increase in airline traffic does not correlate with an increase in passengers and baggage
If it does not correlate , the argument fails .

Hi 4d

Let me know if my below explanation makes sense to you.

The conclusion is that the plan to increase passenger traffic is impractical. And it is so because additional flights will increase passengers or baggage per hour.

Weakener - Now in what scenario additional flight will not increase passengers or baggage per hour

1. One thing that comes to my mind is that the flights are added in a time when there is already low pressure

and option E states that ... whereas option D states that there is no correlation which means with the addition of flights passengers could increase or decrease both... So, we can't say what impact it will have and we can't say that it will not have an impact which the author is mentioning.

Option D is very tempting. It says that an increase in airline traffic does not correlate with an increase in passengers and baggage. This means that if airline traffic increases then passenger traffic will not increase. However, we are not concerned about the airline traffic, that can be handled, as stated in the prompt. We are concerned about the increased passenger traffic. The plan is to increase passenger traffic at the busiest airports.

The plan to increase passenger traffic - How are they going to do that ?
increase in airline traffic

What is the issue? - baggage

increase in airline traffic has no relation with baggage .

D works .

Anyways i dont think this is a well written problem .

Why is the answer not D as it clearly weakens the argument.
