Which of the following best expresses the author's attitude toward the likely fate of the Javan Rhino?Measuring more than five feet tall and ten feet long, the Javan rhinoceros is often called the rarest large mammal on earth. Though the habitat of the Javan rhino once extended across southern Asia, now there are fewer than one hundred of the animals in Indonesia and fewer than a dozen in Vietnam. The decline of the species may have progressed too far to be reversed. For centuries, farmers who wished to cultivate the rhino's habitat viewed the animals as crop-eating pests and shot them on sight; during the colonial period, hunters slaughtered thousands for their horns, as poachers still do today. The surviving Vietnamese herd has diminished to the point that it can no longer maintain the genetic variation necessary for long-term survival. The Indonesian herd cannot be used to supplement the Vietnamese population because, in the millions of years since Indonesia separated from the mainland, the two groups have evolved into separate sub-species. The Indonesian rhinos are protected on the Ujung Kulon peninsula, which is unsettled by humans, and still thought to have sufficient genetic diversity to survive. The lack of human disturbance, however, allows mature forests to replace the shrubby vegetation preferred by the animals. Human benevolence may prove little better for these rhinos than past human maltreatment.
A) optimistic about the Indonesian rhino's long-term survival
B) resigned to the eventual extinction of the species
C) uncertain about the on-going impact of farmers and hunters
D) pessimistic about the species' chances for survival
E) ambivalent about the long-term outcome for the Javan rhinoceros
OA D
I am not sure why D is the right answer. The Javan Rhino is divided into two sub-species, one of which (Vietnamese one) is not likely to survive. But the author is hopeful of the Indonesian Rhino and he ends the passage saying that lack of human presence might help the Indonesian Rhino. D generalizes both the species.
MGMAT's explanation for why choice A is wrong:
(A) The author is certainly not optimistic, as the passage states that "the decline of the species may have progressed too far to be reversed."
But the author is optimistic. The species inhabits a protected area and also mentions to have sufficient genetic diversity required to survive. He also states that there is enough vegetation that the animal can feed on to help its survival.
What am I missing here???
