Inference题目都有规律性吗?

我做阅读时inference的题目做的很不稳定,有时总觉得题目怎么INFERENCE退出来,

那么牵强.请大家看看下面的这篇文章. 有没有什么好办法能提高呀INFERENCE呀?

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 (5) this discovery by exposing small areas of 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 (10) also respond to electrical stimuli, such receptors do so only in response to electrical field strengths about 1,000 times greater than those known to excite electroreceptors.

Having discovered the electroreceptors, (15) 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 (20) 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 (25) 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 to quickly locate unseen (30) prey suggests, according to the researchers, that the anteaters were using their electroreceptors to locate the nesting chambers.

65.   Which of the following can be inferred about the experiment described in the first paragraph?

(A) Researchers had difficulty verifying the existence of electroreceptors in the anteater because electroreceptors respond to such a narrow range of electrical field strengths.

(B) Researchers found that the level of nervous activity in the anteater’s brain increased dramatically as the strength of the electrical stimulus was increased.

(C) Researchers found that some areas of the anteater’s snout were not sensitive to a weak electrical stimulus.

(D) Researchers found that the anteater’s tactile receptors were more easily excited by a strong electrical stimulus than were the electroreceptors.

(E) Researchers tested small areas of the anteater’s snout in order to ensure that only electroreceptors were responding to the stimulus.

Inference

Since this question asks for an inference, the answer is not directly stated in the passage; it must instead be derived from the information given. The question calls attention to lines 1-6, where the experiment is described. The researchers exposed small areas of the snout
                to electrical stimuli and discovered the electroreceptors clustered at the tip
                of the snout. It is reasonable to infer that some portions of the snout exposed to electrical stimuli—those outside the clusters of electroreceptors—did not respond.

A     By showing how sensitive the electroreceptors are, the passage suggests that the range is not narrow.

B      The passage does not report a rise in brain activity corresponding to increased electrical stimulation.

C     Correct. In order to find that electroreceptors were clustered, researchers must have tested areas of the snout outside those clusters.

D     The passage discusses the amount of electrical stimulation required to excite the two kinds of receptors rather than the degree of intensity in the response.

E      Researchers did not know that electroreceptors existed before the experiment, so they could not have conducted the experiment in this way.

The correct answer is C.

不知道INFERENCE是不是有什么规律呀?
