HELP PLEASE ASAP?!

Read the following argument .

Kathleen : My grades have gone up over the past year . Also, I was made captain of the swim team this year. Without being made captain of the swim team, I never would have done so well in school . More students should participate in athletics . What is the primary fallacy in Kathleen's argument ?

1. She assumes that because two things happened at the same time, one caused the other.

2. She has made a circular argument and associated swimming with all athletic activities .

3. She thinks that because it is impossible to prove her argument untrue, she must be correct.

4. She can only think of two possible causes for her good grades
