1. Subject – Verb Agreement Rules

2. Subjects Joined by “and”…

Answer: They (are) at the fair.

3. Exceptions to That Rule…
Rarely, but sometimes, two subjects joined by and represent one object. If that is the case, you should use a singular verb. You can replace the subjects with he, she, or it, and the sentence will work.
Ex: Ice cream and cake (is, are) my favorite dessert.
Answer: It (is) my favorite dessert.
since the SC = one dessert, then the subject must be singular.
