Questions 100-101
            

Zelda: Dr. Ladlow, a research psychologist, has convincingly demonstrated that his theory about the determinants of rat behavior generates consistently accurate predictions about how rats will perform in a maze. On the basis of this evidence, Dr. Ladlow has claimed that his theory is irrefutably correct.

Anson: Then Dr. Ladlow is not a responsible psychologist, Dr. Ladlow’s evidence does not conclusively prove that his theory is correct. Responsible psychologists always accept the possibility that new evidence will show that their theories are incorrect.

101. Anson bases his conclusion about Dr. Ladlow on which one of the following?

 

A.        an attack on Dr. Ladlow’s character

B.        the application of a general principle

C.        the use of an ambiguous term

D.       the discrediting of facts

E.        the rejectiion of a theoretical explanation

Answer-B

Why is B?

Why is not D?---because Dr. Ladlow did not ask others to confirm his conclusion, so his conclusion is discredited.

B) general principle = Responsible psychologists always accept the possibility that new evidence will show that their theories are incorrect

D) 与Anson的论证无关

I understand what u said. thanks so much.

However, D---it says Dr. Ladlow’s evidence does not conclusively prove that his theory is correct

that means Anson ponits out that his credibility of evidence is suspicious.

in this case, why D is not right?

payo

evidence does not conclusively prove

证据不可推结果 不代表证据有问题啊

anistonlucky

对，我的意思是说他考虑用credibility这个理由来攻击，

it may be right, may be wrong,

but Dr says it's disfutable...he's too confident.

so why D is not right, i understand B is right too.

there are two points in this question

1--suspect Dr's credibility

2--cite a principle about the definition of responsiblity.

逻辑题一般不攻击人吧。。。

Dr. Ladlow’s evidence does not conclusively prove that his theory is correct

我觉得应该理解成为证据不足 因为后面一句话是这句的paraphrase

如果理解成证据有问题 那后一句就不必要了

anistonlucky

对，理解为证据不足--因为有可能是对的，也有可能被后人推翻

所以D也可以是对的啊，我拿Dr's credibility of work来攻击他，他的work的plausiblity有suspicious.

难道不行吗？

payo

额。。。选项D是什么意思 难道不是 扭曲事实 的意思？

anistonlucky

我觉得D---数据的真实性，所以我才D can be also right.
