Pikas are small, rabbit-like mammals that live high in the mountains on rocky slopes in western North America. During the 1990s, ecologist Eric Beever revisited 24 locations—all in the Great Basin of the western United States—where pikas had been observed between 1898 and 1947, and he found that seven of the original sites no longer had pikas. The pika populations that had vanished were those at lower, warmer elevations, which suggests climate warming is involved. Generally, when climate warming changes habitat, animals move either to higher, colder elevations or farther north. However, Pikas in the Great Basin are not easily able to migrate in this way. They live on mountain ranges that are separated from other mountains by inhospitable valleys.
Further, even the most widely moving pikas tend to move less than one kilometer from their birthplaces during their lifetimes.
Consider each of the choices separately and select all that apply. [br] Which of the following best describes the function of the highlighted sentence in the context of the passage as a whole?
选项
A、To elaborate on an explanation of a difference between pikas and other animal populations
B、To help explain the statement about pikas that was made in the preceding sentence
C、To present new information that qualifies the findings presented in the second sentence
D、To minimize the significance of information about pikas presented in the preceding sentence
E、To provide evidence that apparently contradicts the observation initially described in the passage
答案
A
解析
本题属于功能题。定位句和前一句很明显都是支持第五句观点的例子。第五句的观点:Pikas…are not easily able to migrate in this way便是在说鼠兔不能迁徙太远,这也是鼠兔和第四句所述的那些可以迁徙的动物之间的区别,因此选项A正确。B项根据定位句的further可知,这句话和前一句并列为两个不同的例子,因此定位句只能用于解释第五句的观点,而不能解释前一句与之不同的例子。C项全篇文章都是在解释第二句的发现,无法用qualify;D项minimize有反驳之意。定位句是和前一句相并列的例子,不能反驳。E项全篇文章都是在解释第二句的观察,没有矛盾。
