Why is E wrong?

Hello I am trying to understand why E is wrong. The stimulus states that a minimum amount of meat is essential to preventing osteoporosis. A vegetarian diet has no meat. Therefore, low incidences of osteoporosis among vegetarians should weaken the nutritionists argument, since it's an example of a group without a requirement for preventing osteoporosis, with low osteoporosis.

Hi @colefanninghaag, the stimulus doesn't precisely tell us that you have to have meat. The term "a minimum quantity" is a bit ambiguous. It could mean "at least x grams per day" of meat and dairy, or it could mean "the least possible amount." In the latter case E clearly strengthens. If, however it means the former (as you understand it) I think the vegetarians still might qualify. We are not exactly told they must eat meat, it is possible they are able to substitute dairy for meat.
