premise: A historic-looking building.
hypothesis: An older building
explanation_1: Just because something is "historic-looking" doesn't mean it is actually historic; it could be a 'younger' building designed to imitate an older one.
explanation_2: Historic-looking does not necessarily imply that the building it actually older, it could be a new structure in a historic aesthetic.
explanation_3: Just because a building is historic-looking does not necessarily mean that it is old.
