Sociologist: A recent study of 5, 000 individuals found, on the basis of a physical exam, that more than 25 percent of people older than 65 were malnourished, though only 12 percent of the people in this age group fell below government poverty standards. In contrast, a greater percentage of the people 65 or younger fell below poverty standards than were found in the study to be malnourished. Each of the following, if true, helps to explain the findings of the study cited by the sociologist EXCEPT: ['People 65 or younger are less likely to have medical conditions that interfere with their digestion than are people over 65.', 'Doctors are less likely to correctly diagnose and treat malnutrition in their patients who are over 65 than in their younger patients.', 'People 65 or younger are no more likely to fall below government poverty standards than are people over 65.', 'People over 65 are more likely to take medications that increase their need for certain nutrients than are people 65 or younger.']
