Hi Jing Jing, thanks for the question.

E is incorrect here because the professor is trying to prove the argument wrong and the argument is saying the following

IP -> FT

The professor's reasoning is

IP -> ID

So stating E, which is diagrammed as FT -> ID, simply makes it such intellectual discipline is another necessary condition for freedom of thought. The entire argument would become.

IP -> FT -> ID

This would not prove the argument wrong. It would just add another necessary condition.

I hope this helps. Please let me know if you have any other questions or would like to expand further!
