What the model leaves out: the subway map

The Seoul subway map is a model that simplifies the real Seoul to the extreme. It keeps only the station-to-station connections, transfer points, and line colors, and erases everything else. Kim, in a neighborhood they're visiting for the first time, is trying to reach a meeting place by relying on the map alone.

Choose the judgment that could go wrong because of the information the map 'left out.' The other three are judgments backed by information the map actually contains.
