Wildcats are improbable candidates for domestication. Like all felids [cats], wildcats are obligate
carnivores, meaning they have a limited metabolic ability to digest anything except proteins.
Wildcats live a solitary existence and defend exclusive territories, making them more attached to
places than to people. Furthermore, cats do not perform directed tasks and their actual utility is
debatable; even as mousers, in this latter role, terrier dogs and ferrets are preferable. Accordingly,
there is little reason to believe an early agricultural community would have sought out and
selected the wildcat as a house pet. Rather, the best inference is that wildcats exploiting human
environments were simply tolerated by people and, over time and space, they gradually
diverged from their “wild” relatives.
2. Which of the following best describes the function of the highlighted sentence in the context of
the passage as a whole
A. It challenges a widely accepted theory presented in the passage.
B. It explains a fact that has long puzzled researchers.
C. It draws a conclusion from evidence presented in the passage.
D. It presents new facts in support of a hypothesis.
E. It formulates a new hypothesis from evidence presented in the passage.
为什么选C不选E?文章不是说 “the best inference”,也就是说文章是根据证据在推测,而不是确凿证明。所以难道不能说是“formulates a new hypothesis”吗?毕竟这也只是推测而已呀
