Don't comment on anything else, you only care about whether it is off topic.
You'd better provide the title of your composition, because propositional composition always makes people feel that "the title is life-threatening." Actually, it is not. Questioners often penetrate the understanding of the topic itself in the stem of the question. Careful examination of the questions will make you suddenly enlightened. Judging from the information you have provided now, your composition is really beside the point. If it is an argumentative paper, then the topic only allows you to discuss the proposition that "a leaf falls to know the autumn of the world", but the final conclusion you draw is that "a leaf falls to know the autumn of the world, and a leaf does not necessarily fall to the world." This is a bit redundant.
No matter how full the argument is, no matter how clear the argument is, no matter how wonderful the argument is, it is meaningless not to focus on the theme.
