Para 1- experts have different views on origins of Varanus; Early researchers' view- Australia to Indo-Australian archipelago; RM's opposite view
Para 2- Komodo dragon distribution- a puzzle; ability to manage body temperature much more efficiently than do mammalian carnivores
1. It can be inferred from the passage that the geographical distribution of the Komodo dragon isD) more restricted than is the distribution of the genus Varanus as a whole- Correct
These carnivores live only on four small islands in the archipelago where, scientists note, the prey base is too small to support mammalian carnivores
2. Which of the following elements in the debate over the origin of Varanus is NOT provided in the passage?A) The evidence that led Mertens to argue that Varanus originated in the Indo-Australian archipelago- Correct
B) The evidence that led early researchers to argue that Varanus originated in Australia- incorrect, Because most existing species live in Australia, early researchers concluded that Varanus originated in Australia and subsequently island hopped westward along the Indo-Australian archipelago.
C) A possible explanation of how Varanus might have spread to the Indo- Australian archipelago if it had originated in Australia- incorrect,
early researchers concluded that Varanus originated in Australia and subsequently island hopped westward along the Indo-Australian archipelago
D) A possible explanation of how Varanus might have spread to Australia if it had originated in the Indo-Australian archipelago- incorrect,
geologic evidence points to a collision between the archipelago and the Australian landmass after Varanus evolved—a fact that could account for the genus’ present distribution.
E) An indication of the general present-day distribution of Varanus species between Australia and the Indo-Australian archipelago - incorrect,
most existing species live in Australia
geologic evidence points to a collision between the archipelago and the Australian landmass after Varanus evolved—a fact that could account for the genus’ present distribution.
3. It can be inferred that which of the following is true of the “geologic evidence” (Highlighted) ?A) It was first noted by Mertens as evidence in favor of his theory about the origins of Varanus.- incorrect, we are never told Mertens used it as an evidence
B) It cannot rule out either one of the theories about the origins of Varanus discussed in the passage.- Correct
C) It accounts for the present distribution of the Komodo dragon.- incorrect; it could account but we can't say for sure
geologic evidence points to a collision between the archipelago and the Australian landmass after Varanus evolved—a fact that could account for the genus’ present distribution.
D) It has led to renewed interest in the debate over the origins of Varanus.- incorrect, no discussion about renewed interest
E) It confirms the conclusions reached by early researchers concerning the origins of Varanus.- incorrect, it weakens the claims of early researchers
