Answer:
There is no linking verb in the sentence above. The verb, studied, would be an action verb.
Explanation:
Linking verbs are verbs that serve as a connection between a subject and further information about that subject. They do not show any action; rather, they “link” the subject with the rest of the sentence. The verb to be is the most common linking verb, but there are many others, including all the sense verbs.
These are the linking verbs
Am, is, are, was and were, being, been, and be, Have, has, had, do, does, did, will, would, shall, should, may, might, must, can, could.
