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. 答案选A，为什么不选D呢作者: aary431 时间: 2010-5-2 14:40
