The punctuation error in the sentence provided is the unnecessary comma before 'when'. After fixing, the correct sentence is: 'Anais Watterson went for a bike ride when she realized it was seventy degrees outside.' Additional sentences were reviewed for correct comma usage.
The sentence 'Anais Watterson went for a bike ride, when she realized it was seventy degrees outside.' contains a punctuation error. The comma before 'when' is not necessary because the clause 'when she realized it was seventy degrees outside' is not independent and cannot stand on its own.
