Answer:
Finally, my daughter published her novels; my son graduated.
Step-by-step explanation:
An independent clause is a clause that can stand alone as a sentence. It contains a subject, a predicate, and expresses a complete thought. If a sentence consists of two or more independent clauses, they must be properly connected either by a comma followed by a conjunction or by a semicolon. Semicolons shouldn't be used to connect more than two clauses and the first word of the second clause is not capitalized.
