Airport official: Local residents have been complaining that

Airport official: Local residents have been complaining that night fights into Plainsville airport disturb their sleep and should be sharply reduced in number. This complaint is completely unreasonable -there have been night flights coming into the airport from the very beginning, twenty years ago, and these residents should have taken that fact into account when buying their homes.

Which of the following is an assumption on which the airport argument depends?

A. There are fewer night flights now than there were originally.
B. The residents who are complaining have been in their current homes fewer than twenty years.
C. The residents who are complaining are ignoring the benefits they gain from the presence of the airport.
D. The economic success of the airport depends entirely on the existence of the night flights.
E. People buying houses in Plainville all avoid buying houses near the airport if they can.

OA: B

Let's debate Why E can't be the correct answer.

Hi RichaChampion,

i think E is wrong because the language is too extreme "all" is not needed.
Plus if you negate it it would be : "not all people buying houses in plainville avoid buying houses near the airport if they can", and this won't weaken the conclusion

I assume we can look at it this way.

Regards,

Joe

Premise: Night flights have been coming into the airport for the past twenty years, a fact that local residents should have taken into account when buying their homes.
Conclusion: It is unreasonable for local residents to complain that night fights are disturbing their sleep.

Apply the NEGATION TEST.
When the correct answer choice is negated, the conclusion will be invalidated.
In other words, the negation of the correct answer choice will show that it is REASONABLE for local residents to complain about noise from night flights.

B, negated:
The residents who are complaining have been in their current homes for twenty years or longer.
Since night flights have been coming into airport only for the last 20 years, residents who have been in their current homes longer than 20 years could NOT have taken night flights into account when purchasing their homes, making it REASONABLE for them to complain about noise from night flights.
Since the negation of B invalidates the conclusion, B is the correct assumption: the answer choice that MUST BE TRUE for the conclusion to be valid.

The correct answer is B.

E, negated:
People buying houses in Plainville do not all avoid buying houses near the airport.
Here, at least one person does not avoid buying a house near the airport.
Since it remains true that local residents should have taken night flights into account when purchasing their homes, the negation of E does not make it reasonable for these residents to complain about noise from night flights.
Eliminate E.
