SDCAR2010【逻辑入门】(七) Strengthen and Paradox
Strengthen and weaken are two sides of the same coin: the difference is only the angle from which you look at the same coin(problem).
Prompts leading to strengthen:
• Which one of the following, if true, most strengthens the argument?
• Which one of the following, if true, most supports the director’s argument?
• Which one of the following, if true, most justifies the teacher’s reasoning?
Prompts that ask you what most justifies the argument are strengthen prompts, while prompts that ask you what justifies the conclusion are sufficient assumptionprompts.
Also, prompts that ask you which answer most supports that passage arestrengthen prompts, while prompts that ask you which answer is most supported by the passage are most strongly supported prompts. The key difference between them is: what is supporting what; is the passage supposed to support the answer or be supported by the answer?
Approach these strengthen questions just as you would weaken questions except that instead of exploiting the argument’s weakness, you are supposed to use NEW information to buttress the argument or to eliminate the weakness.
