25. The indigenous people of Tasmania are clearly related to the indigenous people of Australia, but were separated from them when the land bridge between Australia and Tasmania disappeared approximately 10,000 years ago. Two thousand years after the disappearance of the land bridge, however, there were major differences between the culture and technology of the indigenous Tasmanians and those of the indigenous Australians. The indigenous Tasmanians, unlike their Australian relatives, had no domesticated dogs, fishing nets, polished stone tools, or hunting implements like the boomerang and the spearthrower.
Each of the following, if true, would contribute to an explanation of differences desclibed above EXCEPT:
(A) After the disappearance of the land bridge the indigenous Tasmanians simply abandoned certain practices and technologies that they had originally shared with their Australian relatives. (B) Devices such as the spear-thrower and the boomerang were developed by the indigenous Tasmanians more than 10,000 years ago. (C) Technological innovations such as fishing nets, polished stone tools, and so on, were imported to Australia by Polynesian explorers more recently than 10,000 years ago. (D) Indigenous people of Australia developed hunting implements like the boomerang and the spearthrower after the disappearance of the land bridge. (E) Although the technological and cultural innovations were developed in Australia more than 10,000 years ago, they were developed by groups in northern Australia with whom the indigenous Tasmanians had no contact prior to the disappearance of the land bridge.
They were divided before 10000 years ago. Austrilian learned those techs after they were seperated: more recently
than 10,000 years ago. This explains the difference between the two peoples. 作者: jdxf 时间: 2007-9-13 23:40

You must have rushed yourself.
It's very hard to fight the urge to rush during a preptest.
