1.What is the lecture mainly about?

A The limitations of using computer simulations for archaeological research

B New research that might help solve a mystery about a human migration

C Cultural practices of the first settlers on a group of Pacific islands

D The spread of prehistoric boat-building technologies throughout the Pacific islands

2.According to the professor,what was the purpose of the study that used computer simulations?

A To verify the results of a genetic research project

B To analyze patterns of prehistoric wind and ocean currents

C To identify the most likely routes traveled by prehistoric boats

D To estimate the number of drift voyages that occurred in prehistoric times

3.Why does the professor discuss voyages to the Philippines in the 1660s?

A To emphasize the accuracy of computer simulations

B To imply that Palau was settled long before 4,000 years ago

C To imply that drift voyages occurred frequently in the past

D To suggest that prehistoric sailors had knowledge of ocean currents and wind patterns

4.What does the professor imply about the virtual boats used in the computer simulations?

A More virtual boats should have been included to increase the reliability of the results

B The design of the virtual boats might have been different from the actual boats’ design.

C The virtual boats from Indonesia were bigger than those from the Philippines.

D The biggest virtual boats in the simulations had the best chance of reaching Palau.

5.What do the results of the computer simulations imply about Taiwan?

A Taiwan is more likely than Palau to contain undiscovered artifacts.

B Taiwan’s prehistoric sailors were less skilled than those from New Guinea.

C Taiwan’s prehistoric artifacts are older than those in the southern Philippines.

D Taiwan is not a likely point of origin of the first settlers of Palau.

6.What benefit of the computer simulations does the professor discuss at the end of the lecture?

A They can provide information about the types of vessels used by the prehistoric settlers of Palau.

B They can help archaeologists identify areas within Palau that might contain evidence of prehistoric settlements.

C They can help archaeologists date prehistoric tools and pottery.

D They can help archaeologists determine how quickly the population of Palau grew in prehistoric times.
