The prevalence of a simian virus has been directly correlated with population density in gorillas. Recent fieldwork in the Republic of Dunaga, based on capturing gorillas and testing the gorillas for the virus, has shown that Morgania Plain gorillas are more than twice as likely to be infected than are the Kogula Mountain gorillas. Nevertheless, the population density of Koluga gorillas is significantly greater than that of Morgania gorillas.
Which of the following could best account for the discrepancy noted above?
A. During periods of little rainfall, Koluga gorillas often wander down into the plains in search of food.
B. Dormant strains of the simian virus are often difficult to detect.
C. Due to the Morgania gorilla’s natural habitat and its less reclusive nature, researchers have tested a greater number of Koluga gorillas than Morgania gorillas.
D. Infected Koluga gorillas behave very aggressively and are more difficult to subdue for testing.
E. The Koluga and the Morgania both have similar markings on their backs but are classified as different subspecies.

Option A
Close two were A and C
A. During periods of little rainfall, Koluga gorillas often wander down into the plains in search of food. - explains the discrepancy
C. Due to the Morgania gorilla’s natural habitat and its less reclusive nature, researchers have tested a greater number of Koluga gorillas than Morgania gorillas. - if greater K's were tested, as per hypothesis, then K should be higher by default since they should be infected more.... so it is the opposite of what we want

Higher Population Density (PD) = Higher prevalence of infection
We have to find why the test results showed that M Gorillas are more that twice as likely to be infected than K Gorillas, whereas K Gorillas have a higher PD than M Gorillas.
A. This provides us an additional fact, it does not provide a reason to prove discrepancy. INCORRECT
B. Again, a fact, this would hold true for both M and K Gorillas so we can't infer any discrepancy here. INCORRECT
C. Even if K are more tested, still the discrepancy exists; K still have more PD than M, why didn't the infection ratio show more prevalence in K? Doesn't help solve the paradox. INCORRECT
D. Ah, so it is likely that the fieldworkers who tested K, only tested the ones subdued - which are more likely the uninfected ones; as the infected ones couldn't get subdued easily. This skews the ratio, and helps explain paradox. CORRECT
E. Nothing more than a fact. INCORRECT
