A. In all moderately dim light in which people without the disorder can read large print, people with the disorder cannot read such print. -- in dim light they show normal sensitivity.
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. -- in dim light they show normal sensitivity.
C. These people typically see more acutely at night and in dim light than do most people who do not have the disorder. -- no comparison between people with no disorder vs people with 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. - CORRECT - red color in bright light
E. These people perceive colors other than red in the same way as do most people who do not have the disorder -- no comparison between people with no disorder vs people with disorder

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.
The size of the print is not the problem discussed in teh argument as the disorder is not related to the focus of the lens bu thte sensitivity of the ratina, so out of scope.

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.
The ratina of people with this discussed disorder is insensitive to the red light or red frequency of the visible light,so even if there is no light but red they will be able to see less.

C. These people typically see more acutely at night and in dim light than do most people who do not have the disorder.
The visibilty of peopel with disorder to the visibility of regualr people is not compared but the people with disorder will still see less than the people without 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.
Correct answer since the people with the disorder cannot bear the intensity of bright light and they are less sensitve to red light they can see better with glaases that filter all but red color .Correct answer.

E. These people perceive colors other than red in the same way as do most people who do not have the disorder
This is also a good choice, but people with disorder cannot bear the bright light while people without disorder can this answer choice is susceptible to be negated,
also answer D is better answer then E

This was an interesting question

The only statement that can be supported is D. As people have moderately bright light spectrum except red and D talks about the filtering every color except D for "these people"

The main point of the argument is that people with certain eye disorder can see clearly in dim light and they can see in red light no matter whether it bright or dim .
So we can see that only D is our answer .


A is repeating the information

B White lights are not mentioned in the passage .This may be they case but we do know for sure and it is safe to jump off this option.

C We can deduce this information from the passage so it is also out

D Correct

E Not mentioned in the passage

When I initially saw this question I correctly chose "D." However, when I saw this question I could have sworn that I saw the word "may?" Eyeglasses that are transparent to red components of light but filter out other components of light may help these people see in moderately bright light.

We don't necessarily know indefinitely that eyeglasses would help people see in red light but there is enough evidence to suggest that such glasses probably would help.

Can experts help me out:
I am not questioning the OA, I initially selected D, but after reading B again, the answer choice got me thinking:
If people with the eye disorder are neither sensitive to dim light nor excessively sensitive to the red component of light, why cant "B" be the correct answer? As we know, the EXITS are marked in red as they can be seen more clearly as opposed to other colors.


BEST Support > Support > No support

B. Comparison in "level of seeing" of dim red exit sign and dim white light.
IMO this option can not be an answer inany way.
Nowhere in a passahe is written that these people can see red light better than any dim light. No clear support.
"show normal sensitivity to most components of dim light"
Ok, maybe people see dim red better than dim white (white not in the "most", and red is there). Maybe.
But in option D all is good. We do not have to make any assumptions.
