Answer:
The summer sun is fading; the stars are appearing in the sky.
Step-by-step explanation:
Independent clauses are clauses that can stand alone and act as complete sentences. They contain all elements of a sentence: a subject, a predicate, and they express a complete thought.
If a sentence consists of two or more independent clauses, they need to be properly connected either by a comma and 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.
