Incorrect. This answer is an alternative possibility that the argument concludes won't come to pass, so it's not the main point.

Question Type:
Main Point

Stimulus Summary:
Gigantic planes could hold shops/lounges, but the number of passengers is going to keep increasing and airports can't accommodate more normal-sized planes, so the extra space will probably go to seat more passengers.

Answer Anticipation:
The argument starts with something that could happen in the future, but it pivots ("However") away from it. That pivot is to an alternative prediction about the future of aviation.

Pivots aren't always to conclusions—arguments frequently pivot to facts that refute the opposing point. However, here, the argument pivots to an alternative prediction. Alternatives are frequently conclusions; predictions are frequently conclusions. An alternative prediction? Almost certainly a conclusion!

That's backed up by the rest of the stimulus bringing up information about what will happen in the future backing up that prediction. Let's find this prediction—that the extra space in gigantic passenger planes will likely be used to seat more passengers—in the answer choices.

Answer Explanation:
This answer reflects the prediction the author of the argument makes about what the extra space in the gigantic passenger planes will be used for, so it's the correct answer.

Key Takeaway:
Pivots move from one side to another, but they can be to premises or conclusions. However, predictions are generally conclusions—especially when they serve as an alternative to one raised before a pivot.

Incorrect. This is a statement about a trend that the author uses to support her prediction, so it's a premise of the argument.

Incorrect. This answer supports the prediction that extra space in passenger planes will be used to seat more passengers.

Incorrect. The argument doesn't state that most passengers will fly in these gigantic planes, just that the space in them will go to passenger seating rather than lounges and shops.
