A word or phrase coming between the subject and the verb does not go against the subject-verb agreement. The intervening word or phrase functions as a modifier that modifies the preceding subject.
Examples of the intervening word or phrase include: including, like, plus, with, accompanied by, along with, as well as, in addition to, one of, and together with. The intervening word or phrase does not mean the same as and and so does not compound the subject and make it plural. The subject still determines whether the verb is singular or plural in order to adhere to the subject-verb agreement.
