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 spear-thrower.

Each of the following, if true, would contribute to an explanation of differences described 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 spear-thrower 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.

Correct Answer is B

(B) This answer seems to open up more questions. If these things were developed by the
Tasmanians, why did they stop using them? This answer doesn't help explain our discrepancy, and it is therefore
correct.

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.

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.
> Incorrect. So Tasmanians got bored of the practices and tech and ditched them. Logical enough. Thus eliminate.

B. Devices such as the spear-thrower and the boomerang were developed by the indigenous Tasmanians more than 10,000 years ago.
> This is interesting. If they developed the practices then why did they abandon it? Doesn't provide a logical explanation. Keep.

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.
> So when the land bridge disappeared, neither party had the ability. Post the disappearance of the bridge, Polynesian explorers came to Australia and introduced the new tech to THEM only and not the Tasmanians. Logical enough. Eliminate.

D. Indigenous people of Australia developed hunting implements like the boomerang and the spear-thrower after the disappearance of the land bridge.
> The Australians developed this after the land bridge developed. Explains why Tasmanians did not know about it. Logical enough. Eliminate.

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.
> A specific group of people developed it in isolation and the knowledge transfer never happened. Thus the Tasmanians were not aware of this. Provides a logical explanation. Eliminate.

IMO B.
