The question stem asks us to resolve the discrepancy in the argument. So, our first task is to identify the discrepancy.

We are told that medical research has established that the Beta Diet is healthier than a more conventional diet. However, on average, those who have followed the Beta Diet for several decades are much more likely to be in poor health than are people whose diet is more conventional.

How can we explain this discrepancy that though the Beta Diet has been medically proven to be healthier than a conventional diet, that those who have followed the Beta Diet for several years are--on average--in poorer health than those who follow a more conventional diet?

Well, if the Beta Diet was intended for people who have a condition that worsens their overall health, then it makes sense that despite the fact that the Beta Diet has been proven to be a healthier choice than conventional diets, that those who follow the Beta Diet for several years--on average--are more likely to be in poor health than those whose diet is more conventional, since those who follow the Beta Diet have a condition that adversely affects their health.

This is why answer choice (B) is correct: "The Beta Diet is used primarily as a treatment for a condition that adversely affects overall health."

Hope that helps! Please let us know if you have any other questions.
