Question

Which best describes the punctuation error in the sentence?

Answer 1

The answer to your question would be that what best describes the punctuation error in the sentence is that a comma should be placed after "this weekend". The use of the comma shown in the sentence is the Oxford comma.

An Oxford comma, also called serial comma, is a comma used before the last item in a list of three or more items. When there are three or more items, then you should use a comma with the conjunction (and/or).

Answer 2

There should be a comma right after weekend.

We're not sure if the tickets are for the preview night, the opening night, this weekend, or next week.

Hope this helps you.
