Here's why:
* Action verbs describe an action that the subject is performing. In the sentence "The museum exhibited a new collection of art," the subject (museum) is performing the action of "exhibiting".
* Linking verbs connect the subject to a noun or adjective that describes or renames it. Examples of linking verbs include "is," "am," "are," "was," "were," "seems," "becomes," etc.
