Question

9. Choose the best answer.

Which sentence is correctly punctuated?
After the race, Margarite left early for a dance recital and Elmer hung around.
The weather was hot, and seemed humid, too
Margarite, and Elmer attended the race.
The winner was announced, and I received first place!
O

Answer 1

The last option.
The first one is wrong because Elmer is a new subject and thus makes this a compound sentence. Due to that, there should be a comma before and.
The second is wrong because there is no new subject after “and”. There is simply a new verb, which means there shouldn’t be that comma
The third is wrong because there is no verb between Margarita and the comma to justify the comma. It should be “Margarite and Elmer attended…”
Thus, by deduction, the fourth answer is right
