This argument addresses John's concern about making a connecting flight. The airport with the
connecting flight is very large, consisting of several small stand-alone terminals. The correct answer
choice will support John in concluding that he can likely make his connecting flight thirty minutes
later despite the size of the airport.
(A) Irrelevant. This is a general observation about the timeliness of John's airline, but it does not
provide any new information-it is already established in the premises thllt John's particular
flight arrived on time. The fact that his connecting flight will likely depart on time may even
weaken the argument.
(B) Irrelevant. Airlines have been known to delay flights in order to ensure that a large number of
passengers can make the connection, but we should not have to make an additional assumption
in order to be able to say that this choice strengthens the given conclusion.
(C) CORRECT. Strengthen. This answer choice provides information that John will not have to
leave his terminal in order to reach his connecting flight. The premises describe the terminals as
"small." This information provides us with the strongest piece of information that suggests John
will be able to make his flight within thirty minutes.
(D)Irrelevant. The following flight has no bearing on John's ability to catch the flight on which he
is currently booked.
(E) Irrelevant / weaken. If anything, this choice weakens the idea that John will catch the connecting
flight by shortening the length of time he has to get to the second flight's gate. |
