What is it appropriate to break the rule that requires subjects joined by and to use a plural verb

"It is appropriate to break the rule that requires subjects joined by and to use a plural verb when: the two subjects separated by and refer to the same person or thing. Examples are: Peanut butter and jelly is my favorite sandwich. Red beans and rice is my mom's favorite dish."    

Objective pronoun is the answer.

The lines for all we know could idicate she shoved a whole bag of jelly beans up her rear end. because you're a moron and trying to cheat by having classmate from your online school fill in the next time just put the dialogue in the question too. thx for the points.
