Which function is associated with the glossopharyngeal nerve?

Explanation:
The glossopharyngeal nerve handles both taste from the posterior third of the tongue and motor control for swallowing. Taste fibers from that region travel with IX to be perceived as taste, while a motor branch innervates the stylopharyngeus muscle, which helps elevate the pharynx during swallowing. Hearing, on the other hand, is carried by the vestibulocochlear nerve, not IX. So the function that best fits is taste and swallowing.
