In the sentence "Trayvon, Julie, and Caleb who are members of the drama club, are auditioning for the school musical on Wednesday," a comma should be placed after "Caleb."
The sentence contains an appositive phrase, "who are members of the drama club," which provides additional information about Trayvon, Julie, and Caleb. When an appositive phrase provides non-essential information (meaning the sentence would still make sense without it), it is set off by commas. Therefore, a comma should be placed after "Caleb" to separate the appositive phrase from the main part of the sentence.
By placing a comma after "Caleb," the sentence would read: "Trayvon, Julie, and Caleb, who are members of the drama club, are auditioning for the school musical on Wednesday."
This comma usage helps clarify the information provided about Caleb and ensures the sentence is grammatically correct and easy to understand for the reader.
