O Climate changes that would have favored human population expansion occurred at the time of the extinctions.

O The presence of human hunters had caused animal extinctions in other time periods.

O There was a pattern of climate change earlier than 11,000 years ago that had not caused animal extinctions.

O Harmful climate changes 11,000 years ago would have required humans to hunt larger numbers of animals for food.


6. Which of the sentences below best expresses the essential information in the highlighted sentence in the passage? Incorrect choices change the meaning in important ways or leave out essential information

O A computer model was designed to determine how long it would have taken for  a small group of hunters to spread across North America.

O According to a computer model, people coming into North America 12,000 years ago had to kill game animals in order to feed their population.

7. Which of the following best describes the results of the research discussed in paragraph 4?

O Scientists used mathematical models to show that most of the extinctions occurred in areas where humans had recently arrived.

O Scientists established that the main population of North Americans who hunted lived in Canada during the time of the mega fauna extinctions.

O Scientists used numerical models to confirm that a small population of humans could have caused big-game extinctions in a relatively short period of time.

O Scientists used statistics to prove beyond doubt the currently accepted view that human hunters were the main cause of the mega fauna extinctions.


8. Which of the following statements about Larry Agenbroad's work is implied in the discussion in paragraph 5?

O Agenbroad's showed that Mosimann and Martin's estimates of the amount of time needed to drive big-game to extinction were correct.

O Agenbroad's maps were the first to indicate the ages of the Clovis sites.

O Agenbroad's reinforced the idea that humans could have caused the extinctions.

O To help explain why it is unclear whether all large herbivores of late Pleistocene America became extinct after the appearance of Clovis.



11. Paragraph 7 suggests that Donald Grayson believes which of the following about the remains at Clovis sites and mega faunal extinctions?

O The rapid rate of the spread of humans explains why  the  extinctions  also occurred at a rapid rate.

O The lack of evidence of human-caused extinctions is not surprising in view of the speed with which the extinctions occurred.

O It is likely that more evidence will be found as dating methods improve.

O If humans did contribute to the extinctions, much more evidence of that would have been found by now.


12. Look at the four squares [ ■ ]that indicate where the following sentence could be added to the passage.

One possible nonhuman cause 一 weather cycles 一 is not consistent with what scientists know about the timing of the extinctions.where would the sentence best fit?

O That the first humans migrated to North America near the same time as the extinctions of  the mega fauna has led many to  believe that hunting by humans was  a significant cause of those extinctions.

O Support for the hypothesis that hunting by humans caused the extinctions has been provided by computer models, as well as by the discovery  of  some mammoths' remains near human settlements.

O There is more evidence that human settlers hunted large flightless birds like the moa into extinction than there is that hunters caused the extinction of large mammals like the mammoth.

O Early North Americans known as the Clovis society developed spears in order to hunt enough large animals to feed their population as it expanded across vast areas of the continent.

O Scientists have proven that the human hunters of large animals who migrated across North America grew in number so quickly that they killed off most of the mega fauna within a few hundred years.

O Some scholars argue that the evidence linking mammoth remains to human settlements is insufficient to establish that hunting by humans was a significant factor in the mega fauna extinctions.
