MGMAT RC Quesion - Javan Rhino

by hja379 » Sun Jan 23, 2011 1:13 pm
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.
Which of the following best expresses the author's attitude toward the likely fate of the Javan Rhino?
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???

I think answer is E.

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

If you read the above sentence is second paragraph, it seems human presence is necessary otherwise the forests needed for rhino might not exist.

This can be answered by elimination method .

A) optimistic about the Indonesian rhino’s long-term survival [author is not optimistic about Indo rhino survival]

B) resigned to the eventual extinction of the species [Irrelevant]

C) uncertain about the on-going impact of farmers and hunters [Irrelevant]

D) pessimistic about the species’ chances for survival [yeah author does expresses pessimism regarding survival of Javan Rhino , no better optiion is available to answer ]

E) ambivalent about the long-term outcome for the Javan rhinoceros [The author is not ambivalent about Javan , " The decline of the species may have progressed too far to be reversed" -- This doesnt reflect amivalent approach.]

Doubt about A :- The author expresses a ray of hope , he is not optimistic about Indo rhino . Infact author is more pessimistic about Javan Rhino than optimistic about Indo Rhino.

Hope that helps.
Thanks & Regards,

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.
Thanks for your reply. Where in the lines above (where the author mentions hope for Indo Rhino's survival) does he show pessimism. If he might have said, "Though thought to have some genetic diversty, it is doubtful." Or something along the lines, "The area is protected from humans right now, but there is continued encroaching", which might then imply that the vegetation would not be available for the rhinos for long.

If u read the last line of passage

Human benevolence may prove little better for these rhinos than past human maltreatment.

Author is more concerned about the extinction of Javan Rhino rather than Indo Rhino's possibilty of surviving.

I certainly get what doubt you are having .You want a proof from passage that is pessimistic about Indo Rhino , in matter of fact he is not also optimistic .

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.

Above excerpt is expressing a hope , it is still thought to have , does it give u surety ? And also says that human approach of kindness may prove better than maltreatment.
Thanks & Regards,

I know what you are saying and I guess you are right. Just couldn't completely convince myself.

Hi Raj,

I divided the passage intro manageable chunks and took notes:

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.


Topic: Javan rhino

Scope: ability of rhino to survive

1st chunk: to introduce the endangered Rhino

2nd chunk: to explain why the rhino is endangered & that Viet herd can't survive

3rd chunk: to describe how 1 solution won't work (can't mix the Indo herd -- diff. sub-species)

4th chunk: to emphasize that the Indo herd, though protected, might not survive either (lack of food source)

Overall Purpose: to describe the causes of endangerment & challenges facing 2 rhino species

Question Rephrase: How does the author feel about the fate of the rhino?

Prediction: It needs to be something negative, since the author offers no hope for either species. In fact, he makes it a point to say that the Indo rhino will also likely die out.

We can eliminate A, C and E since they are positive or neutral.

Between "resigned" and "pessimistic," choice D is the more negative choice and therefore correct.

@AIM GMAT I think you are misunderstanding the phrase "may prove little better." That means it will NOT prove better. The author provides no hope whatsoever.
