What causes size variation in bumblebee workers? In pollen storing species larvae develop in individual nest cells and are fed directly by adults. Thus, adults probably
determine
the size attained by each larva. Bumblebee larval cells are not as neatly organized as are those of honeybees, and larvae at the periphery of the brood may receive less care than others. Some researchers may thus believe that ten-fold variation in worker mass results from the accidental neglect of some larvae. However, given that larvae are reared in a controlled environment by specialized nest workers, it seems more likely that this size variation has an adaptive function and that the colonies benefit from rearing workers of a range of sizes. [br] It can be inferred that the author of the passage considers the variation in size of bumblebee workers to be
选项
A、serendipitous
B、unpredictable
C、inconsequential
D、advantageous
E、unfortunate
答案
D
解析
本题问的是作者观点,因此只能定位到第六句,作者认为体型差异有可能是一种适应性的功能,而且巢穴会因此而获益,因此选项D正确。A项认为体型差异是一种意外收获的是some researchers而非作者。
