Answer:
2. The semicolon joins two related independent clauses.
Explanation:
One of the functions of semicolons is to link two independent clauses that are closely related but that are not linked with a conjunction like and, but, or, nor, for, yet, or so. An independent clause is a group of words that have at least a subject and a verb and that express a complete thought on its own, such as the clauses "Leticia has to leave early this afternoon" and "she has a doctor's appointment."
In that sentence, the semicolon is used to join those two independent clauses that are closely related.
