Many studies have shown that individuals who consume a diet rich in fruits and vegetables have lower rates of cardiovascular disease. However, a recent study found that a group of individuals who followed a strict vegetarian diet, which includes only plant-based foods, had higher rates of cardiovascular disease compared to a group of individuals who consumed a balanced diet that included both plant-based and animal-based foods. This finding seems contradictory to the previous studies.

Which of the following, if true, resolves the paradox?

(A) The individuals in the vegetarian group had a higher overall calorie intake compared to the individuals in the balanced diet group.

(B) The individuals in the vegetarian group had a higher average body mass index (BMI) compared to the individuals in the balanced diet group.

(C) The individuals in the vegetarian group had a higher intake of processed vegetarian foods that are high in sodium and unhealthy fats.

(D) The individuals in the balanced diet group had a higher prevalence of pre-existing medical conditions related to cardiovascular health compared to the individuals in the vegetarian group.

(E) The individuals in the vegetarian group had a higher genetic predisposition to cardiovascular disease compared to the individuals in the balanced diet group.

 This question was provided by Unacademy for the Around the World in 80 Questions Win over \$20,000 in prizes: Courses, Tests & more

The effect of BMI, calorie intake and processed food is not mentioned in the passage. We do not know for sure how they will impact the rates of cardiovascular disease. A, B and C are out.
D actually complicates the situation more by providing the counter explanation. D is out.
E gives a clear case of impact on rates of cardiovascular disease on the vegetarian group by mentioning that the vegetarian group had higher risk to begin with. E is the answer.

(B) The individuals in the vegetarian group had a higher average body mass index (BMI) compared to the individuals in the balanced diet group.

(C) The individuals in the vegetarian group had a higher intake of pocessed vegetarian foods that are high in sodium and unhealthy fats.

(D) The individuals in the balanced diet group had a higher prevalence of pre-existing medical conditions related to cardiovascular health compared to the individuals in the vegetarian group.

(E) The individuals in the vegetarian group had a higher genetic predisposition to cardiovascular disease compared to the individuals in the balanced diet group.

The paradox in the argument is that individuals who follow a strict vegetarian diet, which is rich in fruits and vegetables, have higher rates of cardiovascular disease compared to individuals who consume a balanced diet. Option C resolves the paradox by providing an explanation for the higher rates of cardiovascular disease in the vegetarian group. It states that the individuals in the vegetarian group had a higher intake of processed vegetarian foods that are high in sodium and unhealthy fats. This suggests that the quality of the vegetarian diet, specifically the consumption of processed foods, could be a contributing factor to the higher rates of cardiovascular disease. Therefore, option C resolves the paradox by providing a plausible explanation for the contradictory finding.

Option A does not explain why the vegetarian group has higher rates of cardiovascular disease despite consuming a diet rich in fruits and vegetables. Option B does not provide a reason for the higher rates of cardiovascular disease in the vegetarian group. Option D introduces a new factor (pre-existing medical conditions) that is unrelated to the paradox. Option E introduces a genetic predisposition, which is also unrelated to the paradox. Only option C directly addresses the contradictory finding and provides a potential explanation for it.

I have seen many posts given the answer E. That was also my answer. I believe that the genetic predisposition would explain the results. Answer C can only be correct if a higher intake of pocessed vegetarian foods that are high in sodium and unhealthy fats can lead to a cardiovascular disease; however, that information is not in the stimulus.
As I see it Letter C relies on an assumption that may not be true. Without a link between processed food and cardiovascular disease, this answer does not explain the result.
I do not think this is a good GMAT question.

How can the Answer to this question be C when , A and B are also asserts ideas outside the scope of statement .(Higher calorie/Higher BMI/ Processed food are not specifically related to Cardio disease in the statement ). For a group to be distinct from an established similar group there must be any pre existing condition., Like pre-existing a medical condition ..Hence i think E as answer to the paradox. Please correct me if am wrong.

I suppose the main problem here is in the answer key/explanation. Whoever wrote the "official explanation" doesn't seem to have a strong command of how this question type works. E clearly helps to resolve the paradox, while D heightens it. Neither is irrelevant.

C is tempting, but as others have pointed out, we have to rely on real-world knowledge to connect these foods to cardiovascular disease. Also, if we're being precise, it says that the veg group ate more processed VEGETARIAN foods. Maybe the "balanced" group ate more processed animal-based foods, or other unhealthy foods.

So in short, choose answer E (and eat your veggies!), and don't rely too much on sketchy unofficial material!

My choice is C, because it directly solve the paradox between the illness rates of 100% vegetarian and 80% vegetarian
