1. What is the lecture mainly about?
A possible explanation for why prehistoric Tasmanians lived where they did
Evidence showing that Tasmania was populated by humans during the Last Glacial Maximum
The discovery of a series of caves in the mountains of Tasmania
Prehistoric climate change in Australia and Tasmania
2. What does the professor imply about the land bridge that existed between Tasmania and Australia in prehistoric times?
It increased the area where prehistoric Tasmanians could live.
It existed because so much water was frozen into glaciers.
It enabled early Tasmanians to escape intense cold by fleeing north to Australia.
It explains the similarity of the wildlife in Tasmania and Australia.
3. According to the professor, why was it surprising to discover that prehistoric peoples occupied the mountainous regions of southwestern Tasmania?
Archaeologists had assumed that there were no animals there to hunt.
Very little plant life grew at this altitude above sea level.
It had long been believed that early Tasmanians were a seafaring people.
The cold temperatures found in this area seemed inhospitable to humans.
4. What point does the professor make about the wallaby?
The wallaby was the only animal that Tasmanians were able to hunt.
Tasmanians captured wallabies to try to domesticate them.
Wallabies were central to the survival of prehistoric Tasmanian people.
Wallaby meat was difficult to obtain
5. According to the professor, what have archaeologists traditionally assumed about how climate change affected prehistoric societies?
That its main effect was related to the food resources available to the society
That societies were less affected if they had a strong form of central government
That the effects varied according to the society’s ability to clothe itself appropriately
That the effects varied according to the society’s access to adequate shelter and firewood
6. What is the professor’s opinion of the hypothesis that protection from the wind was a key factor in the choices made by prehistoric Tasmanians?
It will probably be the prevailing view of most archaeologists within a few years.
It strongly suggests that more traditional explanations have no merit.
It is convincing in view of the evidence that the researchers uncovered.
It may not account for all of the discoveries that were made in the caves.
