26. The usefulness of lie detectors cannot be overestimated. Although there is no employee screening procedure that is 100 percent accurate, the lie detector is a valuable tool for employers and employees alike. The lie detector’s usefulness is amply demonstrated in a recent survey conducted by a prestigious university. In the survey, those employees of a large company who were applying for a newly created position within the company were asked if they had ever worked on Project X. More than one-third of the applicants studied lied and said they had worked on the project—a project that never existed.
Which one of the following best identifies a flaw in the author’s argument about the usefulness of lie detectors?
(A) The argument depends on the assumption the whatever is good for the employer is good for the employee.
(B) Since lie detectors are known to be less than 100 percent accurate, the test will tend to help only those with something to hide.
(C) By referring to a prestigious university, the author is appealing to authority rather than to evidence.
(D) The study shows only that certain individual will lie, not that the lie detector can detect them.
(E) The author fails to address the issue that the use of lie detectors may fail to prevent embezzlement.
问题：这道题的结论是不是第二句话？按照答案看来应该是说“测谎器有用”，但第一句的意思是说测谎器用途被高估了。是否矛盾？

Test1：SECT1－17. The peculiar evil of silencing the expression of an opinion is that it robs the human race. It takes from posterity, as well as the existing generation, and from those who dissent from the opinion even more than from those who hold it. If the opinion is right, they are deprived of the opportunity of exchanging error for truth; if it is wrong, they lose what is almost as great a benefit: the clearer perception and livelier impression of truth, produced by its collision with error.
Which one of the following best expresses the conclusion presented in the argument?
(A) Silencing the expression of an opinion is robbing the human race.
(B) Silencing the expression of an opinion harms those who dissent more than those who agree.
(C) Anyone who agrees with an opinion would not want to silence its expression.
(D) Gaining a clearer perception and livelier impression of truth is a great benefit.
(E) The greatest benefit is the opportunity of exchanging truth for error.

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.
问题：感觉C和D也是假设。个人理解如下：
C：如果雇主现在不依照排名的话，学校控制分数膨胀进而提高排名可信度的做法就没有意义了；
D：如果低分学生和高分学生找工作没有区别的话，控制分数以提高其参照度的做法也就没有意义了。

SECT1－17：是指题干吗？
题目在唠叨言论自由的好处。
压制言论是对人性的剥夺，对后代、当代人的剥夺；对持不相同意见的人的剥夺比对持相同意见人的剥夺更剧烈。表达不同的意见的好处：若意见正确，将避免错误；若意见错误，它的好处也是很多的：通过与错误意见的比较，可以使对真理的认识更清晰。

13、不同意你的意见。
C：顾主依赖荣誉排名。则，目前学校大派荣誉学位的做法就是对的。
D：这个是无关的选项。
