I've found that in most subjects the questions asked are highly specific. It is best to stick to what is asked and formulate whatever you are writing in relation to that. Some people have a tendency to write whatever they know about a topic because for 20 marks one needs a lot of material. But remember quality over quantity. For example last year in current affairs paper the first question was; "China-Pakistan Economic Corridor (CPEC) is considered as a game-changer. How the CPEC can be helpful to uplift the Pakistan’s economy? Discuss." Now of course you can write an introduction and an overview of the projects linked with CPEC but going into depth about each and every one of them (and who is responsible for them) is redundant. You are not asked to just reproduce data. You need to formulate the data in the light of the specific question asked (in this case the effects on Pakistan's economy and an overview of what it means for the world. You can break this later part down further into; regional game-changer, implications for the prevailing world order, implications for world trade, etc etc).

If in any case the question has an "either/or" statement then yes, pick a side and back it up with your arguments. Be as relevant and clear to the question asked as possible.
