这是解析，我不够聪明~看不懂啊
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.
