Answer 1

There is an elevator in the building, so we

Have to and must climb the stairs.

Answer 2

Answer:

There is an elevator in the building, so we wouldn't have to climb the stairs.​

Explanation:

The sentence clearly states that the building has an elevator. So, the blank will have '' wouldn't have to'' as whenever there is an elevator we do not climb the stairs. We always take the easier path that is the elevator.
