Students because their is referring to the students. Students is the antecedent because an antecedent is just a phrase that replaces the third-person personal noun. Their would be the personal noun. Hope this helps!
I want to help but what's supposed to be bolded?
A complex sentence can be created by adding an incomplete thought to a complete thought. It can also be created by taking two simple sentences and making one into a big sentence, which would be half a paragraph. I honestly, don't always write correctly so I use Grammerly. My whole class uses it. This sounds as if I'm advertising, but I'm not.
