Ans Exp:

As this comes under must be true or proven question type we must able to point out or prove the answer from from the question so let's find out

As the question is comparing the two airports so by careful examination we can say that by not considering the climatic conditions the Mayville Airport has less number of delays than New comb Airport so climatic conditions make more delays in Mayville Airport than Newcomb Airport more delays so we must prove this.

A.This states that climate conditions are responsible for delays in Mayville airport so this must be out choice
B. The question does state about climatic conditions but did not say about how worse so eliminate this
C.mechanical problems are not mentioned in the question so eliminate this (we should remember in proven or must be true family questions that if anything not mentioned in the Passage is mentioned in choices then we should straight forward eliminate it .)
D.what ever Airports are better equipped to handle weather conditions ,the planes can be safe within the Airport but who know's what happened when they fly so eliminate this and we should also consider that we are not discusses about weather equipment in question so eliminate it.
e.As we are talking about the delays of departure not about the arrivals ,so eliminate it on this basics.

Hope it helps and clear.

at first C is more lucrative answer to me. but it is a conclusion question. so conclusion must be within the scope of the stimulus. then i took A

IMO strong contenders are A and B.

Marked B but i think the answer is A.
Wrong with B is the the weather between the two airports is nowhere mentioned in the stimulus.

This is a startight A.

All other options are either Irrelevant or Out of Scope. Conclusion should strictly come from argument. No inference.

I did not get the answer..
-> M airport experiences 26 delay per 100 flights..
-> N airport experiences 20 delay per 100 flights..
due to bad weather , Mayville Airport has 5 fewer departure delays per 100 flights than Newcomb Airport does
that means there is less departure delay is taking place at M than airport N...due to weather
now option 1 says exactly opposite...

b) On average, the weather at Mayville Airport is worse than it is at Newcomb Airport.not necessary, maybe both mayville and newcomb have similar weather conditions but newcomb's airport is more efficient in such conditions because of there mechanical, communication adequacy
c) Mechanical problems cause a greater number of delays at Newcomb Airport than at
Mayville Airport.out of scope
d) The fleet of airplanes leaving from Newcomb Airport is better equipped to handle inclement
weather than the fleet of airplanes leaving from Mayville Airport.out of scope
e) Mayville Airport experiences a greater number of arrival delays per 100 flights than
Newcomb Airport does.out of scope, as we are discussing about departure scenario

When the delays caused by bad weather is disregarded the number changes to

M - M Delay per 100 flights
N - M+5 Delay per 100 Flights

Lets Say M is 10

M - 10 per 100 flights
N - 15 per 100 flights


So we can conclude that due to bad weather more flights gets delayed at M airport (16) compared to N(5). Hope its clear

Which of the following conclusions is best supported by the information given above?

A. Bad weather causes a greater number of departure delays at Mayville Airport than at Newcomb Airport.

B. On average, the weather at Mayville Airport is worse than it is at Newcomb Airport.

C. Mechanical problems cause a greater number of delays at Newcomb Airport than at Mayville Airport.

D. The fleet of airplanes leaving from Newcomb Airport is better equipped to handle inclement weather than the fleet of airplanes leaving from Mayville Airport.

E. Mayville Airport experiences a greater number of arrival delays per 100 flights than Newcomb Airport does.

[Reveal] Spoiler: OE
When drawing a conclusion, we must remember not to conclude too much. In
this case, we are looking for the conclusion that comes directly from the
information given without requiring any additional assumptions.
(A) CORRECT. In general, Mayville experiences a greater number of delays per
100 flights than Newcomb does. However, when delays caused by bad weather
are discounted, Mayville has 5 fewer delays per 100 flights. Since the two
airports run the same number of flights, bad weather must cause a greater
number of delays at Mayville Airport than at Newcomb Airport.
(B) While we can conclude that Mayville experiences a greater number of delays
caused by bad weather, we cannot make any conclusions about the relative
weather conditions at either airport. It is very possible that the airports experience
the same weather, but that for some reason Newcomb’s airport is better
equipped than Mayville’s airport to handle inclement weather (e.g. the fleet of
aircraft at Newcomb is better suited to bad weather, or the air traffic controllers at
Newcomb are more competent, etc.). Some other factor could cause the
discrepancy in weather related delays aside from the weather conditions being
different.
(C) While we can conclude that Mayville experiences a greater number of delays
caused by bad weather, we have no information about delays caused by
mechanical problems. There may be other reasons aside from either bad
weather or mechanical problems that account for departure delays (e.g. human
error).
(D) We have no information regarding the quality of airplane fleets at either
airport.
(E) The argument gives no information about arrival delays.

C. Mechanical problems cause a greater number of delays at Newcomb Airport than at Mayville Airport.

D. The fleet of airplanes leaving from Newcomb Airport is better equipped to handle inclement weather than the fleet of airplanes leaving from Mayville Airport.

E. Mayville Airport experiences a greater number of arrival delays per 100 flights than Newcomb Airport does.

If want to approach by rejection than this problem is easy.
Reasons for delay can be many weather, airplane's functioning, type of facilities at airport so any one reason given for the given change in number of delays will be wrong.
B , C , D : wrong because it is not mentioned which reason leads to this departure delays. It can be any other reason.

E is wrong , no mention of arrival delays and nothing is mentioned about any co-relation about arrival delays and departure delays. So nothing can be inferred.

Now option A is left. hence correct

This can be also proved by doing some maths
Take number of flights 100
Newcomb airport 20 departure delays, after disregarding weather: assume X
Mayville airport 26 , after disregarding weather X-5
Now delays due to weather in Newcomb= 20-x
delays due to weather in Mayville airport= 26-(x-5)= 31-x , which is greater than 20-x
Hence proved that bad weather causes a great number of departure delays at Mayville airport than Newcomb airport

Logically also it can be proved
If delays is more(Mayville airport) at the start and disregard weather affect than delays is less , than it can be concluded that weather affect causes a great number of departure delays

A IS CORRECT

straight A. As both the number of departures are same and after disregarding one condition the higher departure rates comes down implies that this condition is the sole factor and option a sates precisely that

Inference Question- The answer to inference question can be-
1. Restatement of a given premise
2. Logical deduction that is tight withing the boundaries of the argument.

Mayville Airport and Newcomb Airport have the same number of flight departures each day. Mayville Airport experiences 26 departure delays per 100 flights, while Newcomb Airport experiences 20 departure delays per 100 flights. When delays caused by bad weather are disregarded, Mayville Airport has 5 fewer departure delays per 100 flights than Newcomb Airport does. Which of the following conclusions is best supported by the information given above?

The argument states that even though the percentage of DEAPRTURE delays ( 26/100) at Mayville Airport is less than that at the Newcomb Airport (when delays due to weather are discounted), Mayville actually has 5 fewer departure delays.The number of flights is the same.

A. Bad weather causes a greater number of departure delays at Mayville Airport than at Newcomb Airport-Only possible LOGICAL DEDUCTION that is within the SCOPE of the argument.Weather delays have been talked about in the argument.

B. On average, the weather at Mayville Airport is worse than it is at Newcomb Airport.-Irrelevant because we are discussing only delays due to weather .

C. Mechanical problems cause a greater number of delays at Newcomb Airport than at Mayville Airport.- Out of Scope- a good weakner but not a good inference answer

D. The fleet of airplanes leaving from Newcomb Airport is better equipped to handle inclement weather than the fleet of airplanes leaving from Mayville Airport.-Out of scope

E. Mayville Airport experiences a greater number of arrival delays per 100 flights than Newcomb Airport does.-Irrelevant because we are concerned with departure delays

A is correct

Answer should be B.
Without bad whether, M has fewer delays than N airport. The number of delays in M is otherwise higher.

A and B were somewhat close to the logic. After elimination, reached A as the correct one.

OA is A

use this for reference: http://gmatclub.com/forum/inference-revision-mayville-airport-and-newcomb-airport-have-193143.html?fl=similar

Mayville Airport and Newcomb Airport have the same number of flight departures each day.
Mayville Airport experiences 26 departure delays per 100 flights,
while Newcomb Airport experiences 20 departure delays per 100 flights.
When delays caused by bad weather are disregarded, Mayville Airport has 5 fewer departure delays per 100 flights than Newcomb Airport does.


A. Bad weather causes a greater number of departure delays at Mayville Airport than at Newcomb Airport.

B. On average, the weather at Mayville Airport is worse than it is at Newcomb Airport.

A and B are the strongest contender for the OA if we use the process of POE as C D E are out of scope and also, I am not taking them here to discuss. Option B uses a very strong word "on average" as it is no where mentioned about the average or daily figure, we are only told that each day there are 100 flights that depart from both airports (each)
and normal day MA = NC - 5
on bad weather day MA = 26 but NC =20.
so you cannot take if this bad weather day happens once in a day/month/quarter/ or in decades :)

I hope this helps.

i am not clear with the logical deduction of the numbers given in the passage.
It says that 26 departure delays per 100 flights for Mayville as compared to 20 departure delays per 100 flights for Newcomb.Then it says that 5 fewer departure delays per 100 flights for Mayville,so does it no become the following:

Mayville Newcomb
26/100 20/100
26-5=21/100 20/100

So basically, Mayville has more departure delays compared to Newcomb???
Its my doubt,please clarify
