Question

correct the text by inserting two commas. (note: in this skill, serial commas are not optional.)
im fairly certain ms. quinn that ellie is graduating from college with a degree in biology next year.

Explanation:

Commas are used to set off direct addresses. In the sentence, "Ms. Quinn" is the person being directly addressed. So, we need to insert commas before and after "Ms. Quinn" to separate it from the rest of the sentence.

Answer:

I'm fairly certain, Ms. Quinn, that Ellie is graduating from college with a degree in biology next year.
