LSAT SET 22 SECTION II 18，25
Dillworth: More and more people are deciding not to have children because of the personal and economic sacrifices children require and because so often children are ungrateful for the considerable sacrifices their parents do make for them: However, such considerations have no bearing on the fact that their children provide the best chance most people have of ensuring that their values live on after them. Therefore, for anyone with deeply held values, foregoing parenthood out of reluctance to make sacrifices for which little gratitude can be expected would probably be a mistake. Travers: Your reasoning ignores another fact that deserves consideration children's ingratitude for parental sacrifices usually stems from a wholesale rejection of parental values.
18. Dillworth employs which one of the following argumentative strategies?
(A) showing that considerations cited as drawbacks to given course of action are not really drawbacks at all
(B) exposing as morally suspect the motives of people who would make the choice that Dillworth rejects
(C) indirectly establishing that a given course of action is obligatory by arguing that the alternative course of action is prohibited
(D) distinguishing a category of person for whom the reason presented in favor of a given course of action is more telling than the reasons cited against that course of action
(E) using evidence that a certain course of action would be appropriate under one set of conditions to arrive at a general conclusion about what would be appropriate in all cases.
KEY：D。感觉是D，但是实在理解不了。可以讲讲为什么吗？
25. S: It would be premature to act to halt the threatened "global warming trend," since that alleged trend might not be real. After all, scientists disagree about is, some predicting over twice as much warming as others, so clearly their predictions cannot be based on firm evidence. W: Most scientist consider discussions of accepted ideas boring, and prefer to argue about what is not known, According to the International Science Council there is a consensus among reputable investigators that average global warning in the next century will be from 1.5 to 4.5 C.
W's rejoinder proceeds by
(A) denying the existence of the disagreements cited by S
(B) accepting S's conclusion while disputing the reasons offered for it.
(C) relying on authorities whose views conflict with the views of the authorities cited by S
(D) putting disagreements cited by S in perspective by emphasizing similarities.
(E) reasoning in a circle by accepting evidence only if it agrees with a desired conclusion.
KEY D
I can not find where is the similarities cited by W. Could anyone help me to explain it? |
