I have a doubt, ok the answer is E and the other answ choices are easy to eliminate,but in E there is an assumption that the other airport will not be a regional hub. Because if it is I don't think E could be correct. because ok if I am free to assume that the Hevelia airstrip could be also a regional hub I will not be able to solve the problem,I think.
In many CR questions I don't know how much I can assume from the answer choices can someone help mE?


It's a good doubt, E requires the assumption that 40 miles is too far and airlines won't re-schedule their flights to use that as the new hub. To me this doesn't be a problem, 40 miles isn't far when you are flying at blazing speed.

C to me is a great contender: more development = more congestion, thus we don't get the added benefits. But C is more uncertain than E, therefore E is correct. Does it make sense? Sorta, but not great. It's one of those cases where we just hail to the GMAC lords.

It is a bit odd to see that the right answer in a "strengthener" question attacks a premise! the new airport was supposed to be an "attractive alternative" as mentioned in the stimulus. Are you sure of the source of this question?


This is from OG 13 – #22 in the CR section.

This is framed as a Strengthen question, but it's actually best to think of it as a Weaken!

Note that the argument is deconstructed as

- We need a 10% reduction to help with delays.
- Expanding a nearby airport could make that airport attractive for up to 20% of the passengers.

Then the "experts" basically say "this plan won't work". Since we're asked to justify the experts' opinion, we could think of this as weakening the unstated conclusion "this plan will work."

(E) does not attack a premise. Rather, it basically gives a reason for why switching to the alternative airport won't be a good option for the airlines. The premise states that switch would be appealing to the passengers. Well, if it's appealing to the passengers, but the airlines have a reason not to do it, that weakens the claim that the plan will work!

Hope that helps!

adding to it:
the premise says
1.to avoid delays,10 percent reduction in schedule flight is needed
2.20 percent people can be attracted to the new airport
but the argument never says that 20 percent passengers are needed to divert to other airport to avoid delay
so the strengthener is not attacking the premise
here the strengthener will suggest that even after the alternate airport is fully developed, people will not switch to the new airport ,but rather use the old airport
option e gives such a reason.
