I would also recommend making an outline for all the questions before you start them-at least in rough. I made all of mine on the last sheet of the answer book. As soon as I got any question paper I would make a quick rough outline-more like a mind map- in the first ten minutes for at least 5 questions then would chose the four I felt are the strongest. I don't think it ate up much of my time and in fact while writing made sure that I didn't deviate and remembered to include all the key points.

I didn't include the outlines in the actual body of the paper unless I felt that the outline I had come up with was out of this world and would add something to the overall appeal of the question.

For the specific example you have given above I would make a simple mind-map of all their differences that come to mind at that moment. I'll of course add to the list I originally come up with while writing or might even subtract some that don't make sense but its a good way to begin the paper-shows you right off the bat which questions you attempt will be stronger then the others.

Also note that this question, i.e. differentiate between gender and women studies, actually did come in 2019 but has several other parts to it like historically tracing the need for gender studies as a distinct subject and also its scope and significance in Pakistan. So there are in fact enough parts to make a thorough outline which would also serve the dual purpose of making sure you don't miss a part of the question since a lot can be written on each individual sub-section alone.
