Explanation:
In English, structures in sentences MUST be balanced. That is to say, the sentence has to have parallelism in structures. In grammar, parallel structures are those which have the same grammatical structure. For example, in the first sentence several nouns are repited, and it would be incorrect if we put another structure (a verb phrase, for example) in the middle of a enumeration of nouns.
As in many languages, in English, the subject has to agree or concord with the verb; this is called subject/verb agreement. That is, if the subject is singular, the verb MUST be singular, and if the subject is composed of two or more people/objects, the verb MUST be plural. If not, there is a serious grammar mistake, which makes ungrammatical the complete sentence.
