Identify the sentence structure: “She studied hard, yet she didn’t pass the exam.”

Correct answer: Compound. The sentence joins two independent clauses with the coordinating conjunction “yet”, which makes it a compound sentence.

• Simple: A simple sentence has only one independent clause, but this one has two.
• Complex: A complex sentence needs a dependent clause, but both clauses here can stand alone.
• Compound-Complex: A compound-complex sentence needs two independent clauses and at least one dependent clause, and there is no dependent clause here.
