Explanation on the subject:
The correct conjugation of these verbs is the infinitive form, since in the given sentences, the verbs are in the third person singular (he, she, you) in the present and past tense. It is important to remember that in Spanish the conjugation of the verb changes depending on the person and the tense. For example, the verb "visit" in the first sentence is in the third person singular (él, ella, usted) in the present, therefore it is conjugated as "visita".
