When selecting a nest, the female of the river blenny (a small fish) appears to be sensitive to both size and orientation. Blennies deposit their eggs preferably in nests under large stones and in nests facing southeast. Southeast-facing nests contain larger egg clutches, a fact that cannot be completely explained by differences in nest stone sizes. Moreover, in a recent study,
current speeds
upstream of the nest and at the nest entrance were similar for nests facing southeast and those facing in other directions. A southeast-facing entrance per se thus seems to be the specific nest feature preferred by females, rather than the effect of selective positioning on current at nest entrance. The reasons for this preference are unclear, however.
The author of the passage considers “current speeds” in order to
选项
A、identify a factor that undermines the significance of nest stone size for female river blennies
B、indicate one possible advantage of river blenny nests that do not face southeast
C、eliminate a possible explanation for a nest orientation tendency among female river blennies
D、indicate why female river blennies are sensitive to both size and orientation of possible nests
E、suggest a reason why many female blennies prefer southeast-facing nests
答案
C
解析
本题属于功能题,定位句3s版本便是排除掉水流速度对巢穴朝向的影响,因此选项C正确。A项削弱石头大小这一因素的句子是第三句,定位错误。B项文中未提及。D项文中未提及。E项本句话只能排除水流速度这一因素,但是还解释不了喜欢东南朝向的原因。
