premise: People are coming down a movable staircase built through a tunnel, which has three of those staircases.
hypothesis: People are descending in a tunnel.
explanation_1: Coming down a staircase is inarguably descending; doing so through a tunnel is therefore descending in a tunnel.
explanation_2: Descending is the same as coming down.
explanation_3: Coming down and descending have the same meaning.
