标题: LSAT-11-4-14

14. In a learning experiment a researcher ran rats through a maze. Some of the rats were blind, others deaf, others lacked a sense of smell, and others had no sensory deficiencies: yet all the rats learned the task in much the same amount of time. Of the senses other than sight, hearing, and smell, only kinesthesia had not previously been shown to be irrelevant to maze-learning. The researcher concluded on the basis of these facts that kinesthesia, the sensation of bodily movement, is sufficient for maze-learning.

The researcher’s reasoning is most vulnerable to which one of the following criticisms?

(A) The small differences in proficiency found by the researcher did not appear to fall into a systematic pattern by group.

(B) The possibility that the interaction of kinesthesia with at least one other sense is required for maze-learning cannot be ruled out on the basis of the data above.

(C) It can be determined from the data that rats who are deprived of one of their sources of sensory stimulation become more reliant on kinesthesia than they had been, but the data do not indicate how such a transference takes place.

(D) It can be determined from the data that rats can learn to run mazes by depending on kinesthesia alone, but the possibility that rats respond to non-kinesthetic stimulation is not ruled out.

(E) It can be determined from the data that maze-learning in rats depends on at least two sources of sensory stimulation, one of which is kinesthesia, but which of the remaining sources must also be employed is not determinable.

答案：B

的确不太明白答案再说什么？：（可能是阅读的问题：（

能不能也帮我分析一下其他选项错在哪里，多谢了：）

原文：原文试验老鼠，它们每种的感官各缺一种，还有一种是三种感官都好。但它们的某种能力一样。因为所有感官中，只有kinesthesia没有证明和这种能力无关，所以说kinesthesia充分导致了这种能力有关。它没有排除的可能性就是kinesthesia和三种感官中的至少一种共同导致这能力（因为尽管每种老鼠缺一种感官，却还有别的两种）。即B。其它容易排除。

谢谢，Lawyer，这下彻底明白了：）

Spot the question type: Weaken

K ---> Maze learning ---> only K had not been shown to be irrelevant to maze learning

Apparently, we know that K is necessary for maze learning; however, is it sufficient for maze learning ? We dont know that.

So, what we are going to do is to choose one answer which best attack the sufficiency of K to guarantee the maze learning.

A. Its not really relevant. Why should it matter ?

B. True that, what if it has to be the interactions between K with other senses to sufficiently lead to learn maze learning ?
