31. What does the grey whale example show?
32. How was the seabed-hibernation idea finally rejected?
33. Why was Aristotle's theory wrong?
34. Why was the Newfoundland humpback discovery important?
(A) is incorrect. The recording does not support this option: Some whales stay near one coast.
(B) is correct. Grey whales are described as travelling more than twelve thousand miles between Arctic feeding waters and Mexico.
(C) is incorrect. The recording does not support this option: Some whales breed in Arctic waters.
Associated Text:
Others, like the grey whale, travel more than twelve thousand miles seasonally between feeding waters in the Arctic and the warm lagoons of Mexico.
(A) is incorrect. A and B are not mentioned.
(B) is incorrect. A and B are not mentioned.
(C) is correct. Experiments on captive marine mammals showed whales have no hibernation instinct.
Associated Text:
experiments were done on captive marine mammals in the 1940s, which demonstrated that whales have no hibernation instinct.
(A) is incorrect. The recording does not support this option: he confused whales with fish.
(B) is correct. Aristotle observed real seasonal changes, such as skin loss, but wrongly interpreted them as one species changing into another.
(C) is incorrect. The recording does not support this option: he ignored dolphin behaviour.
Associated Text:
These assumptions are understandable, given that this pair of species are similar in shape, but they are a classic example of an incorrect interpretation based on correct observations.
(A) is incorrect. The recording does not support this option: it proved whales could survive hunting injuries.
(B) is incorrect. The recording does not support this option: it identified a new Atlantic whaling fleet.
(C) is correct. The embedded harpoon came from the Pacific, proving that the whale had travelled between distant oceans.
Associated Text:
it was the first piece of physical proof that whales travel between distant oceans.

Write the correct letter
A-H next to questions 35-40.
The correct answer is A because Aristotle's explanation was transmutation, the idea that one species changed seasonally into another.
Associated Text:
He developed the theory of transmutation, the seasonal change of one species into another, by observing whales and dolphins
The correct answer is D because the seventeenth-century cave theory claimed that whales spent winter sleeping inside enormous underwater caves.
Associated Text:
whales spent the winter sleeping inside enormous underwater caves, hidden far beyond the reach of any boat.
The correct answer is F because the 1856 humpback discovery involved a long harpoon embedded in the whale's flank, giving physical proof of long-distance movement.
Associated Text:
the long harpoon embedded in its flank, which incredibly had not killed it.
The correct answer is B because photographic identification recognises whales from the same fluke pattern.
Associated Text:
tagged whales are seen again at the place they have migrated to and identified by the same fluke pattern.
The correct answer is G because the tagging method involved putting numbered tags on whales' fins to gather information about migration routes.
Associated Text:
putting numbered tags on their fins became established.
The correct answer is E because the 1925 publication was the first detailed migration chart of Pacific humpback whales.
Associated Text:
In 1925, the first detailed migration chart of Pacific humpback whales was published,
