If you mean what substances are present in paper, then it is principally cellulose. If you are asking about substance A in a question paper, it's a way of referring to an unknown substance so it can ask you questions based on the information given about it. For instance, if it says 'substance A turns damp red litmus blue' then you know that substance A is an acid.
