There are many different parts of a sentence. There are subjects which are what the sentences are about. Verbs are what the subjects do. After the verbs there will be either a direct object or an indirect object. Just like there can be a compound subject, there can be a compound verb and a compound direct object. One example would be Sara and Bob walked to the store.
This sentence contains a compound subject. Sara walked and ran to the store. This sentence contains a compound verb. I bought hamburgers and pizzas. This sentence contains a compound direct object. It shows what was bought. Direct objects take the action of the verb. It is what is accepted by the verb.
Look at this sample sentence with multiple objects.
My friends and I visited Rome, Paris, and London during our European vacation. The names Rome, Paris, and London answer the question what? about the transitive verb visited.
