Issues:
Be very careful about definitive black and white answers.
Your statement about Severe damage is not totally correct. With severe damage you may have N1 rotation but equally you may not. You may also have no N2 rotation.
The conditions people see in the sim do not represent all situations you could be faced with and sometimes they can also not represent real world symptoms, you have to use good technical UNDERSTANDING and problem assessment skills to identify the malfunction.
