To check the subject-verb agreement in the given sentence, we need to identify the subject and the verb and make sure they agree in number.

Subject: "Robert's friend Steve, as well as his wife"
Verb: "are going"

The subject is plural because it consists of two entities: "Robert's friend Steve" and "his wife." Therefore, the verb "are going" is also correct because it agrees with the plural subject.

So, your answer is correct.
