Humans have a very strong bias toward right-handedness, with approximately 85-90% having right as their dominant hand. Among studies of nonhuman primates, James Welles’s 1976 study of captive chimpanzees and catarrhine monkeys reported more right-handed individuals than left-handed ones, but Jane Goodall’s 1963 study of wild chimpanzees did not find a tendency toward right-handedness. It’s important to note, however, that captive animals spend significantly more time with humans than wild animals do, and therefore __________

A
the apparent difference between the two studies results may be partly attributable to the 1963 study using a different standard to determine handedness than the 1976 study did.
B
the number of individuals in the study of wild chimpanzees is probably too small to support the claim that no tendency toward right-handedness was found in that population.
C
the number of individuals in the study of captive chimpanzees and catarrhine monkeys is likely too small to support the claim that the species tends toward right-handedness.
D
the right-handedness exhibited by the captive chimpanzees and catarrhine monkeys might be, in part, an effect of extended contact with humans.
