Example #3:  The crevasse yawned.
(Most frequent verb sense inappropriate)

There is only one sense for crevasse in WordNet, and it belongs to n-object.  This doesn’t work as a subject of body verbs, so the verb sense fails (matching with no subjects and failing to fill its external role).

There is another sense of yawn (“be open, gape, yaw”) which does fit with natural objects, and this sense matches.
