GWD-11-Q31,好像没有讨论过

GWD-11-Q31:


People with a certain eye disorder are virtually unable to see in moderately bright light, which seems to them unbearably intense, since the cells of their retinas are overwhelmed by moderately bright light.
These people do, however, show normal sensitivity to most components of dim light.
Their retinal cells are also not excessively sensitive to red components of moderately bright light.

The information above best supports which of the following hypotheses about people with the disorder described, if they have no other serious visual problems?



A.
In all moderately dim light in which people without the disorder can read large print, people with the disorder cannot read such print.

B.
In an otherwise darkened concert hall, these people will see a dimly illuminated red exit sign more clearly than small dim white lights that mark the aisles.

C.
These people typically see more acutely at night and in dim light than do most people who do not have the disorder.

D.
Eyeglasses that are transparent to red components of light but filter out other components of light help these people see in moderately bright light. (D)

E.
These people perceive colors other than red in the same way as do most people who do not have the disorder.

这题可能还是阅读问题吧?

一种眼睛的疾病,让患者看不见中等亮度的光,因为这种光对于他们太刺眼了。但是这些患者可以看见弱光,而且也可以看到中等亮度光中的红光部分。

问哪个结论可以被题目支持。
只有D吧。

谢谢祥解,但此题也太绕了吧,考试时真得这么分析么?有没有别的方法阿

楼上不妥

形式逻辑角度

if P then -Q, and if -P then Q, and if R then -P

问加强,加强是加强结论,并列命题加强一个也可以算加强

D, if R then -P,if -P then Q, 所以加强结论if P then -Q

请各位指正。

其实有点像数学

x>0 a=0

X<0 A=1

X>0 red=1

answer

有一种办法可以使 X>0 red=1

这种病,

外界亮的时候,觉得特别亮,嘛都看不见,

外面暗的时候,和正常一样,

外面亮的时候,对红色的视觉是正常的,

问下面怎么才能支持上面

A 外面一般暗---病眼在暗处不如常眼,不支持题干

B 暗处对红光敏感-----没有落到题干范围内,无关

C 病眼在暗处更厉害----没说暗处病眼更厉害,说在暗处和常人一样,矛盾

D 在外面一般亮的时候,红墨镜把外面光线变成等强度的红色,能帮助病眼看

外面,---完全支持,虽然看到的是红色背景,但是还是可以算得视觉正常。

E 红色以外,----没说红色以外会如何,无关
