sir, we have to include 1st para in our answer or not. I think it is irrelevant or not purposeful.
i understand it is little extra and not directly related . Objective should be to understand to increase content and not decrease it from exam point of view. Studying pm gives us info how to increase the content . So I will say learn small things which are question specific from pm and try to increase content rather that decrease it. Because more content more marks . Definitely keep it relevant as per question and pm
