试题详情
文章：
When species are extensively hunted, individuals that reach reproductive maturity early make up a larger proportion of the population, because they have a better chance of reproducing.

These considerations may help settle whether the primary cause of the gradual disappearance of North America's mastodons, prehistoric animals related to elephants, was diminished food resources or human hunting, since __________.
题目：
Which of the following most logically completes the reasoning?
选项:
A、from the location of certain hunting weapons in juxtaposition with mastodon remains, it is possible to determine whether those weapons were used to hunt mastodonsthe average age at which mastodons reached reproductive maturity can be established from mastodon tusks, of which there are many fossils dating from different periods
B、from the remains of mastodons already discovered, it can be accurately estimated when mastodons became extinct
C、from tusks and other bones, it is possible to determine whether male and female mastodons reached reproductive maturity at about the same age
D、it is possible to determine whether the earliest human dwellings constructed from mastodon tusks and bones come from an earlier period than the earliest hunting weapons unambiguously associated with mastodon remains
