LSAT3-I-6.7

Questions 6-7

Rotelle: You are too old to address effectively the difficult issues facing the country, such as nuclear power, poverty, and pollution.

Sims: I don't want to make age an issue in this campaign. so i will not comment on your youth and inexperience.

7. Rotelle is committed to which one of the following?

(A) Many old people cannot effectively address the difficult issues facing the country.

(B) Those at least as old as Sims are the only people who cannot effectively address

the difficult issues facing the country.

(C) Some young people can effectively address the difficult issues facing the country.

(D) If anyone can effectively address the difficult issues facing the country, that

person must be younger than Sims.

(E) Addressing the difficult issues facing the country requires an understanding of

young people's points of view.

答案D,

1)我认为A和D都是R说的等价命题,为何A错?原文中Rotelle说的话明显是对Sims类似人身攻击，怎么能　打击一大片，且older的标准是什么呢，D则以Sims为基准，爽，确切

2) Rotelle is committed to ...中的committed　请查字典，谢谢!
