Having discovered the electroreceptors, researchers are now investigating how anteaters utilize such a sophisticated sensory system. In one behavioral experiment, researchers successfully trained an anteater to distinguish between two troughs of water, one with a weak electrical field and the other with none. Such evidence is consistent with researchers' hypothesis that anteaters use electroreceptors to detect electrical signals given off by prey; however, researchers as yet have been unable to detect electrical signals emanating from termite mounds, where the favorite food of anteaters live. Still, researchers have observed anteaters breaking into a nest of ants at an oblique angle and quickly locating nesting chambers. This ability quickly to locate unseen prey suggests, according to the researchers, that the anteaters were using their electroreceptors to locate the nesting chambers.

问
The passage suggests that the researchers mentioned in the second paragraph who observed anteaters break into a nest of ants would most likely agree with which of following statements?

A: The event they observed provides conclusive evidence that anteaters use their electroreceptors to locate unseen prey.

B: The event they observed was atypical and may not reflect the usual hunting practices of anteaters.

C: It is likely that the anteaters located the ants'nesting chambers without the assistance of electroeceptors

D: Anteaters possess a very simple sensory system for use in locating prey

E: The speed with which the anteaters located their prey is greater than what might be expected on the basis of chance alone.

我选的是A，正确答案是E。先不说A，E为什么对呢？都没有提到相关的内容吧。 PS：答案和文章都是从GMAT阅读大全里面来的。
