Passage
Measuring more than five feet tall and ten feet long, the Javan rhinoceros is often called the rarest large mammal on earth. None exist in zoos. Like the Indian rhino, the Javan has only one horn; African and Sumatran rhinos have two. While the Javan rhino habitat once extended across southern Asia, now there are fewer than one hundred of the animals in Indonesia and under a dozen in Vietnam. Very little is known about Javan rhinos because they lead secretive and solitary lives in remote jungles. Until recently, scientists debated whether females even have horns, and most scientific work has had to rely on DNA garnered from dung.
The near extinction of the Javan rhino is the direct result of human actions. For centuries, farmers, who favored the same habitat, viewed them as crop eating pests and shot them on sight. During the colonial period, hunters slaughtered thousands. Now, human efforts to save them may well prove futile. The Vietnamese herd is probably doomed, as too few remain to maintain the necessary genetic variation. Rhinos from Java cannot supplement the Vietnamese numbers because in the millions of years since Indonesia separated from the mainland, the two groups have evolved into separate sub-species. In Indonesia, the rhinos are protected on the Ujung Kulon peninsula, which is unsettled by humans, and still have sufficient genetic diversity to have a chance at survival. Ironically, however, the lack of human disturbance allows mature forests to replace the shrubby vegetation the animals prefer. Thus, human benevolence may prove little better for these rhinos than past human maltreatment.
Q. The author’s attitude toward current human efforts to save the Javan rhino can best be described as
  • a)
    optimistic and worthwhile
  • b)
    pointless and doomed
  • c)
    idealistic but profitable
  • d)
    problematic and ironic
  • e)
    confused but heroic
Correct answer is option 'D'. Can you explain this answer?

PassageMeasuring more than five feet tall and ten feet long, the Javan...
In the second paragraph, after citing human actions as the cause of the Javan rhino’s plight, the author goes on to mention that the population in Vietnam is probably not viable and that human efforts in Indonesia, such as the protection of the rhino on the Ujung Kulun peninsula, have had mixed results. The passage ends with the thought that human benevolence is not helping the rhinos much more than past maltreatment. Thus, the correct answer will note the problems with current human efforts.
(A) The author is certainly not optimistic, as the passage mentions that in Vietnam the outlook is doubtful and in Indonesia, problems plague the effort. It is possible, although not certain, that the author considers the effort worthwhile.
(B) The author gives no indication that he or she believes the effort is pointless. Furthermore, especially in Indonesia, the passage does not indicate a certainty that it will fail.
(C) The passage does not at all discuss the profitability of the effort. It is possible, although not certain, that the author considers the effort idealistic.
(D) CORRECT. The discussion of the mixed results and poor prognosis for the population in Vietnam justifies “problematic.” The last sentence of the passage, observing that benevolence has proved little better than maltreatment justifies “ironic.” Also, the author references the ironic quality of human protection of the Javan rhino in the 8th sentence in the 2nd paragraph, “Ironically, however, the lack of human disturbance allows mature forests to replace the shrubby vegetation the animals prefer.”
(E) The passage indicates that the efforts have been much less than entirely successful but does not indicate any confusion related to the current efforts. It is possible for efforts to be less than fully successful without being confused. Furthermore, it does not at all address the idea that any particular heroism is involved.
