From this last sentence of the first paragraph, you do know that the rhinoceros' faith is not deemed yet.

Quote:
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.


The answer is D

Hope this helps

Thanks for clearing my query

OFFICIAL EXPLANATION

1.
The correct answer to this question will be a claim that must follow from text contained in the passage. This question does not provide any clues as to where the justifying text will be found.
(A) The first paragraph mentions that the the Javan rhino is the most endangered species of large mammal. However, it does not have to be true that it is one of the most endangered animals, a category that is far broader than mammals.
(B) CORRECT. The first paragraph states that very little is known about the life of the Javan rhino. The passage does indicate, however, that scientists have been able to extract information on the species’ DNA from gathered dung. The paragraph also suggests that very little information about female Javan rhinos has been gained, given that scientists only recently discovered whether or not females of the species even have horns. Thus, one can infer that more is known about the genetics of the Javan rhino than its mating patterns.
(C) The second paragraph indicates that hunters slaughtered many rhinos, but it does not mention where. Furthermore, it does not have to be true that more rhinos were killed in Vietnam simply because fewer rhinos remain there.
(D) The passage only discusses the Javan rhino; therefore, a generalization about the extinction of "most animals" is not supported by the passage.
(E) The passage does not mention other survival factors for a species or rank them; therefore, this inference is not supported by the passage.
2.
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.
3.
The author mentions the number of horns in the first paragraph in the course of describing the Javan rhino. The correct answer must follow from this text.
(A) Although the Javan rhino is described as rare, the discussion of extinction is in the second paragraph,. Furthermore, the vitality of the African rhino is not mentioned.
(B) The passage contrasts the number of horns of the Javan rhino to that of the African and Sumatran rhinos. However, the author makes a parallel comparison to the Indian rhino because both species have one horn.
(C) The passage only discusses the Javan rhino’s evolution into a separate subspecies in the second paragraph in a completely different context,; no direct link is drawn between this evolution and the Javan rhino’s single horn.
(D) CORRECT. The author mentions the Javan rhino’s single horn in conjunction with a general description of the Javan rhino. The passage then goes on to discuss its habitat and the scientific knowledge to date. Thus, the author included this detail to add depth to his or her description.
(E) The passage only states that until recently scientists were unsure if females had horns, and no definitive answer is given. Furthermore, this point is mentioned in a different context, after the passage has finished describing the Javan rhino.
4.
The first paragraph describes the Javan rhino and indicates how little is known about it. This should be reflected in the answer. It is the second paragraph that relates the effects of human activity on the rhinos and their chances for survival.
(A) This choice is too broad, as the paragraph focuses on the Javan rhino and only mentions its differences from some other rhinos to distinguish the species from others.
(B) This answer choice describes the topic of the second paragraph, not the first.
(C) CORRECT. The first paragraph provides the known facts about the Javan rhino and indicates that much remains unknown.
(D) The steps taken to save the Javan rhino are only mentioned in the second paragraph; they do not appear in the first paragraph.
(E) The first paragraph only indicates the respective number of rhinos in Indonesia and Vietnam in passing, and does not mention the differences between the two groups. The fact that the two have evolved into separate sub-species is mentioned only in the second paragraph.
5.
The passage mentions the Ujung Kulon peninsula in the second paragraph. Immediately before that, the passage states that Indonesian Javan rhinos cannot supplement those in because they have evolved into separate sub-species. The correct answer choice will rely upon this fact.
(A) CORRECT. This choice rephrases the information in the second paragraph which states that the Indonesian Javan rhinos have evolved into a separate sub- species.
(B) The passage does not mention the aquatic abilities of the Javan rhino nor can it be assumed that they would have to get there without human assistance.
(C) The passage does not discuss the funds available in either country; therefore this choice is incorrect.
(D) The passage does not mention the difficulty involved in capturing a rhino; therefore this choice is incorrect.
(E) The passage does not mention terrorist activity at all; therefore, this choice is incorrect.
6.
In the second paragraph, the passage states that the “near extinction of the Javan rhino is the direct result of human actions.” The correct answer must be justified by that statement.
(A) Rhino deaths at the hands of farmers are mentioned as a detail and as just one of the human actions responsible. It does not single farmers out as the primary cause of the Javan rhino’s near extinction.
(B) The passage mentions the separation of from the mainland to explain why the Javan rhino population in Vietnam cannot be supplemented by rhinos from Ujung Kulon. It is not discussed as a reason for the near extinction of the Javan rhino.
(C) Rhino deaths at the hands of hunters are mentioned as a detail and as just one of the human actions responsible. It does not single hunters out as the primary cause of the Javan rhino’s near extinction.
(D) The passage does not say that current human efforts are at all responsible for the near extinction of the Javan rhino. Instead, it indicates that current benevolent human efforts may not prove sufficient to save them.
(E) CORRECT. The beginning of the second paragraph clearly states that human actions, taken as a whole, have directly caused the near extinction of the Javan rhino.

1. Which of the following can be inferred from the passage?

A. Javan rhinos are one of the most endangered animals on the planet.
B. More is known about the genetics of the Javan rhino than is known about its mating patterns.
C. Hunters killed more Javan rhinos in Vietnam than in Indonesia.
D. Most animal extinctions are the result of human actions.
E. Genetic diversity is the most important factor for the survival of a species.

How can we say that the DNA gathered from dung of female rhino does not give same level of details?
