Which of the following sentences contains a non-restrictive clause that requires punctuation?

 The book store that is on the corner carries my favorite comic book.

 The book store that Justin likes is open until 10:00 p.m.

 The corner book store the one that sells coffee has the best cookies.

 The corner book store with the red awning has finally opened

wach · Answer

The third one requires commas between 'store' and 'the' and between 'coffee' and 'has', because it adds detail and is separate from the clause.
