John was flying from San Francisco to New York with a connecting flight in Chicago on the same airline. Chicago's airport is one of the largest in the world, consisting of several small stand-alone terminals connected by trams. John's plane arrived on time. John was positive he would make his connecting flight 30 minutes later because _________.

Which of the following most logically completes the argument above?


John has only 30 minutes to make a connection in a very large airport with separate terminals. The missing support must show why he would not need much time to get from one flight to the other. The best reason is that both flights would be in the same terminal.

(A) John's airline is known for always being on time

This is not enough. His first plane already arrived on time. The issue is whether he can physically reach the connecting flight in 30 minutes.

(B) a number of other passengers on John's first flight were also scheduled to take John's connecting flight

This does not guarantee that John will make the connection. Other passengers having the same connection does not mean the connection is easy or certain.

(C) at the airport in Chicago, airlines always fly into and out of the same terminal

This is correct. Since both flights are on the same airline, John would arrive and depart from the same terminal. That makes a 30-minute connection much more realistic.

(D) John knew there was another flight to New York scheduled for one hour after the connecting flight he was scheduled to take

This does not explain why John would make his scheduled connecting flight. It only gives a backup option.

(E) the airline generally closes the doors of a particular flight 10 minutes before it is scheduled to take off

This weakens the argument. It means John effectively has only about 20 minutes, not 30 minutes.

Answer: (C)

Hi Reva22,

Happy to walk through this one. It's a "fill in the blank" argument, and the trick with these is to first spot the worry the setup plants, then find the choice that erases exactly that worry.

Here's the setup, piece by piece:

- John has only 30 minutes between landing and his connecting flight.
- Chicago's airport is one of the largest in the world, made of "several small stand-alone terminals connected by trams."
- Despite all that, John is positive he'll make the connection.

So the blank has to give us a reason that makes 30 minutes clearly enough - even in a huge, spread-out airport. The one danger the passage highlights is having to hop between far-apart terminals by tram, which eats time.

Why (C) is right: "airlines always fly into and out of the same terminal." This means John lands and departs from the same terminal - no tram ride across the airport. The scary part of the setup disappears, so 30 minutes is plenty. That directly justifies his confidence.

Why the others don't work:

- (A) On-time reputation - irrelevant; his plane already arrived on time. The issue is getting across the airport, not whether flights run late.
- (B) Other passengers making the same connection doesn't help John physically reach the gate any faster.
- (D) A backup flight an hour later would explain being relaxed about missing this one - not being confident he'll make it.
- (E) Doors closing 10 minutes early actually shrinks his time - that would make him less confident, not more.

One quick note on the phrasing you may have seen questioned in the thread: "connecting flight 30 minutes later" just means his next flight departs 30 minutes after he lands - that's his connection window, not a delay. Only (C) removes the terminal-crossing risk inside that window.

Answer: C
