Explanation:

Part a

The sentence has a misplaced modifier. The phrase "with an ear - to - ear grin" should describe Jolene, not the test. So we need to reposition the modifier.

The participial phrase "Scrubbing the shower with bleach and a brush" should modify a person (the one doing the scrubbing), but the subject of the main clause is "the mold stains" which can't do the scrubbing. We need to add a subject who is doing the scrubbing.

The phrase "To finish by the 6pm deadline" is an infinitive phrase that should modify the doer of the action. But the subject of the main clause is "the computer keys" which can't finish the deadline. We need to make the subject a person who can do the action.

Answer:

Error? Y
If error, revise: Jolene, with an ear - to - ear grin, was delighted when Professor Yancey returned her perfect calculus test.
