• B. TheJavan rhinos cannot swim to Vietnam and have no land route available
• C. Neither Vietnam nor Indonesia has the funds for such a project.
• D. Javan rhinos in the Ujung Kulon peninsula are almost impossible to capture.

Answer 1

The correct option is A

The Indonesian Javan rhinos constitute a separate sub-species.

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 Vietnam 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 subspecies.
(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.
