Spot the question type: Must be true ( Necessary Assumption )

Core of the argument:

Revenues from the fees of users of private aircraft using the airport was lower than expected, thus airport was unable to pay its operating expenses.

let us predict few possible necessary assumptions

1. there are not any other fees to cover for the gap.

2. there are no any reason behind that airport can't charge enough amount from those users.

3. there are no any possibilities that the operating expenses inevitably inflated to the point higher than what predicted.

Let us dive into the options

A. So ? We are discussing user of the private aircrafts.

B. It does not really impact the argument after negating it.

C. So ? we are discussing the relationship between the operational expenses to the revenues charged from the users of private air craft.

D. Negate it. The operating expenses were " not " greater than thee revenues raised from sources other than the user fees for private planes. Perfectly refute the conclusion if the expenses are lower or equal to the other revenues streams, it must " able to " pay for it.

E. Not relevant.
