Hi teachers,
Could you correct these directions? Do they need any commas?
Read the questions and if possible answer them without looking at the article. Write your answers in the space provided or circle the letter of the correct answer.

Thanks in advance.

You can, but don't have to, put commas around "if possible."

Otherwise, fine.
