103. The author of the passage most probably discusses the

function of tactile receptors (lines 7-11) in order to

(A) eliminate and alternative explanation of anteaters’

response to electrical stimuli

(B) highlight a type of sensory organ that has a function

identical to that of electroreceptors

(C) point out a serious complication in the research on

electroreceptors in anteaters.

(D) suggest that tactile receptors assist electroreceptors

in the detection of electrical signals.

(E) introduce a factor that was not addressed in the

research on electroreceptors in anteaters.

请问此题为什么选A，盼思路，谢谢。

初步看，文章中，为加强其结论中电子感受器的有效性，作者区分了与触觉感受器的不同，从而通过排除他因的办法来加强了作者的论述。

希望楼上能明白了。如果仍有疑问，再好好看看解释，或许可以解决。：）

请指正。
