This question presents the "Yorgorian Paradox": the Yorgorian people consume high amounts of protein RX7G (linked to coronary heart disease) but have a lower incidence of heart disease than the industrial nation of Transpraxia. We are tasked with explaining this paradox.
Let's analyze the answer choices:
(A): This only states that some jungle meats have higher concentrations of RX7G compared to farm meats. This doesn't explain the paradox, because it doesn't address why the Yorgorians have a lower incidence of disease despite consuming more of the protein. Not helpful.
(B): This tells us that Transpraxians consume almost the same amount of RX7G per capita as the Yorgorians. However, it does not explain the difference in heart disease rates between the two populations. Not helpful.
(C): Some restaurants in Transpraxia serve jungle meats. Again, this does not explain the lower incidence of heart disease among the Yorgorians. Not helpful.
(D): This suggests that the Yorgorian diet is high in berries that neutralize the harmful effects of RX7G. This directly addresses the paradox, as it provides a reason for the lower incidence of heart disease: the nutrients in the berries counteract the harmful protein. This helps explain the paradox.
(E): This only states that Yorgorians eat jungle meat multiple times a day. It doesn’t explain why they are less affected by the harmful protein. Not helpful.
Conclusion:
The best answer is (D) because it provides a potential explanation for why the Yorgorian people are not suffering from heart disease despite consuming high levels of RX7G—their consumption of berries neutralizes the harmful effects of the protein.
