Quizplus · Accepted Answer

Multiple studies have suggested a link between the Epstein-Barr virus (which causes mononucleosis) and an increased risk for multiple sclerosis. Therefore, a young woman with a history of mononucleosis living in New York is at the highest risk for multiple sclerosis among the options given. Age, gender, location, and family history may also play a role in the risk for multiple sclerosis, but the presence of a known risk factor (i.e. history of mononucleosis) makes option D the best choice.
