PREP2012-Pack1-RC-009-02 VRC000630-02 Easy Which of the following, if true, would most weaken the author's argument in the highlighted text? A. Cub-carrying behavior has been observed in many non-myrmecophagous mammals. B. Many of the largest myrmecophagous mammals do not typically exhibit cub-carrying behavior. C. Some sloth bears have home ranges that are smaller in size than the average home ranges of black bears. D. The locomotion of black bears is significantly more efficient than the locomotion of sloth bears. E. The habitat of black bears consists of terrain that is significantly more varied than that of the habitat of sloth bears.
highlight 部分的内容是指: Furthermore, the daily movements of sloth bears and American black bears - which are similar in size to sloth bears and have similar-sized home ranges - reveal similar travel rates and distances, suggesting that if black bear cubs are able to keep up with their mother, so too should sloth bear cubs. |
