Explanation:

Part a

The sentence has a dangling modifier issue? Wait, no. Wait, the subject of the main clause is Jolene, and the participial phrase (though there isn't one here, it's a when - clause). Wait, actually, the sentence is correct. The professor returned her test, and Jolene was delighted. The "ear - to - ear grin" is the professor's? Wait, no, the structure: "Jolene was delighted when Professor Yancey returned her perfect calculus test with an ear - to - ear grin." The prepositional phrase "with an ear - to - ear grin" modifies Professor Yancey (who is doing the returning), so the sentence is grammatically correct.

The participial phrase "Scrubbing the shower with bleach and a brush" should modify the subject of the main clause. But the subject of the main clause is "the mold stains", and mold stains can't scrub the shower. So there's a dangling modifier error. To correct it, we need to make the subject of the main clause the one doing the scrubbing.

The infinitive phrase "To finish by the 6pm deadline" should modify the subject of the main clause. But the subject of the main clause is "the computer keys", and computer keys can't "finish by the 6pm deadline". This is a dangling modifier error. We need to make the subject a person who can finish the task.
