12. If Country X does not intervene militarily in Country Y, then the whole region will definitely fall under enemy influence.
It most logically follows from the statement above that, if Country X does intervene militarily in Country Y, then the whole region.
(A) Will definitely fall under enemy influence
(B) Will probably fall under enemy influence
(C) Will probably not fall under enemy influence
(D) Will definitely not fall under enemy influence
(E) May or may not fall under enemy influence
解题思路:是不是A推出B,A非推出B的方向不定,所以答案是E,B的不对是不是在表述上不如E精确?
前一段都凭感觉做题,错误率也还可以,可是昨天错了一踏糊涂,开始恶补逻辑知识,希望你们可以帮我.
13. Top college graduates are having more difficulty demonstrating their superiority to prospective employers than did the top students of twenty years ago when an honors degree was distinction enough. Today’s employers are less impressed with the honors degree. Twenty years ago no more than 10 percent of a given class graduated with honors. Today, however, because of grade inflation, the honors degree goes to more than 50 percent of a graduating class, Therefore, to restore confidence in the degrees they award, colleges must take steps to control grade inflation.
Which one of the following is an assumption that, if true, would support the conclusion in the passage?
(A) Today’s students are not higher achievers than the students of twenty years ago.
(B) Awarding too many honors degrees causes colleges to inflate grades.
(C) Today’s employers rely on honors ranking in making their hiring decisions.
(D) It is not easy for students with low grades to obtain jobs.
(E) Colleges must make employers aware of the criteria used to determine who receives an honors degree.
这道的B选项为什么不对,是取非以后不会削弱原文吗?这道题的解题思路是什么样?要抓住什么?我做的时候是这么想,结论要控制GRADE INFLATION,假设它对结论有加强的效果,所以答案B,请问这个解题思路的失误在哪里?
12。否命题不一定成立。即可成立,也可不成立。BC错在只说一种情况
13。答案为A,而非B。原文逻辑:过去有不超过10%的HONORS,现在有多余50%HONORS,所以GRADE膨胀了。如果现在学生比过去优秀,那GRADE就不膨胀那个了。A排除这种情况。故为假设。
1。B的错误在于too many honors degrees ,你必须假设怎样才算太多。故错
2。原文用和20年前比较的方式得出现在的情况,然后得出一个结论说要control grade inflation。那作者已假定现在存在grade inflation的问题(不存在这个问题如何需控制)。也就是作者虽然说要control grade inflation,实际是说现在存在grade inflation的问题,就是两个结论是一样的。LSAT题在结论上常有花招,就是换一种说法说出来。

非常清楚,谢谢!
