托福閱讀真題及答案（4）

paragraph 5—6

Many scholars continue to support this scenario.For example,geologist Larry Agenbroad has mapped the locations of dated Clovis sites alongside the distribution of dated sites where the remains of wooly mammoths have been found in both archaeological and purely paleontological contexts.These distributions show remarkable synchronicity(occurrence at the same time).

There are,however,many problems with this model.Significantly,though a few sites are quite impressive,there really is very little archaeological evidence to support it.Writing in 1982,Martin himself admitted the paucity of evidence;for example,at that point,the remains of only 38 individual mammoths had been found at Clovis sites.In the years since,few additional mammoths have been added to the list;there are still fewer than 20 Clovis sites where the remains of one or more mammoths have been recovered,a minuscule proportion of the millions that necessarily would have had to have been slaughtered within the overkill scenario.

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

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

B.Agenbroad’s maps were the first to indicate the ages of the Clovis sites.

C.Agenbroad reinforced the idea that humans could have caused the extinctions.

D.Agenbroad’s studies of wooly mammoths led to his discovery of Clovis sites.
