In "Why Literature," Mario Vargas Llosa lays out an argument for the importance of literature in a person's life. One of my favorite quotes from Llosa is: "But literature has been, and will continue to be, as long as it exists, one of the common denominators of human experience through which human beings may recognize themselves, and converse with each other, no matter how different their professions, their life spans, their geographical and cultural locations, their personal circumstances." Using this as a springboard for a discussion, which works this semester have completed the goal set out for literature by Llosa? Which three works have been the "common denominators of human experience through which human beings may recognize themselves"?

This assignment asks you to be thoughtful, reflective, and synthetic regarding the texts read during the course. You don't mention the specific readings the course engaged in, other than the original one quoted above, but the prompt is pretty universal. A successful essay would likely follow this format:
Begin with a universal statement about how literature engages us in awareness of self and of others, how it speaks to a shared humanity, and how it opens our minds to the common thread uniting our wildly diverse experiences and realities. You can quote Llosa's passage as a focusing lens since the quote provided is meant to be a springboard. Your thesis statement will both identify the universal human quality you select and identify three of the texts your read that all illuminate that quality.
Supporting paragraphs could merely discuss each of the three different titles in a separate paragraph, all focused on the theme you select. More interesting and likely more successful would be paragraphs that put two or maybe all three together to show how they illuminate an aspect of the theme. Do they all reveal something true about interpersonal relationships, or do they all reveal something about the value of self-awareness or reflection? Do two stand in contrast to each other, showing a successful or unsuccessful approach to a similar dilemma? You need to be efficient with your selection of detail (though you must reference and quote), but you do not want to be deficient with the value of your thought. Make sure your topic sentences are spot-on in terms of illuminating that connection literature makes among individuals.
In your conclusion, you will want to reflect and extend on what reading and thinking about your chosen theme offers a person who wants to lead a more meaningful human life. What is at the core of your readings that speaks to the human desire for connection and meaning?
