Read an essay about aids,and you think about aids. But you can also think about the essay. Does it discuss preventive strategies or medical treatments? Or both? Does it describe aids symptoms or offer statisticd? Is the disease presented as a contagious disease. A biblical scourge , or an individual experience? What evidence is relied on? Does it quote medical authorities or offer anecdotes from everyday people ? Does it appeal to reason or emotions? These are not questions about what a text says,but about what the does. They are not about aids,but about the discussion of aids.
