og 103这个正确答案怎么翻译？

Passage 38
Australian researchers have discovered electroreceptors
(sensory organs designed to respond to electrical fields)
clustered at the tip of the spiny anteater’s snout. The
researchers made this discovery by exposing small areas of
(5) the snout to extremely weak electrical fields and recording
the transmission of resulting nervous activity to the brain.
While it is true that tactile receptors, another kind of
sensory organ on the anteater’s snout, can also respond to
electrical stimuli, such receptors do so only in response to
( 10) electrical field strengths about 1,000 times greater than
those known to excite electroreceptors.
Having discovered the electroreceptors, researchers are
now investigating how anteaters utilize such a sophisticated
sensory system. In one behavioral experiment, researchers
(15) 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,
( 20) 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
(25)to locate unseen prey suggests, according to the researchers, that the anteaters were using their electroreceptors
to locate the nesting chambers.

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
246
research on electroreceptors in anteaters.

答案是A

可是eliminate是动词，而altternative是形容词两个词怎么同时修饰explanation啊？A怎么翻译？

og解释说

Choice
E is not correct because the information in lines 7-11 is presented in addition to information about
the experiment and not as a criticism or to point out an omission.

是说：7－11行是在说除关于试验的信息外，7－11行并没有批评或指出一个疏漏吗？

再问104提

10 4. Which of the following can be inferred about anteaters
from the behavioral experiment mentioned in the
second paragraph?
(A) They are unable to distinguish between stimuli
detected by their electroreceptors and stimuli
detected by their tactile receptors.
(B) They are unable to distinguish between the electrical
signals emanating from termite mounds and those
emanating from ant nests.
(C) They can be trained to recognize consistently the
presence of a particular stimulus.
(D) They react more readily to strong than to weak
stimuli.
(E) They are more efficient at detecting stimuli in a
controlled environment than in a natural
environment.

用排除法也可以选对选项C是正确的，但是consistently好像文中并没有提啊，c怎么翻译呢？

10版OG把an打成了and,是type error.
