Step-by-step explanation:
Based on previous data, Junto's belief that most people do not interact in an elevator because it is a confined space and they feel awkward is true.

The behavior of commuters in train stations, where they tend to be focused on their journey and avoid unnecessary interactions, can be applied to elevators as well.
