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

A: we don't know anything about "moderately dim light" - out of scope
C: the passage does not say if the disorder 'hightens' the limited capabilites to compansate for the weakness -out of scope
D: there is no mention of eye glassese: out of scope
E: gain, we have no proof for this claim

--
A. In all moderately dim light in which people without the disorder can read large print, people with the disorder cannot read such print. - Moderately dim light not much of an issue
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 have normal sensitivity to most components and nothing has been said about white

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 mentioned

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

E. These people perceive colors other than red in the same way as do most people who do not have the disorder - can't say. They still have some sensitivity towards red.

Essentially ppl w/ this disorder have trouble seeing in moderate bright light except for red. No real problems w/ dim light.

A: nothing about reading, and this is not suggested.
B: nothing to suggest they see red more clearly, they just dont have problems seeing it in moderately bright light.
C: This isnt what the passage says, this goes too far.
E: maybe maybe not, cannot deduce this.

D: sure, if these glasses really do this then it would help these people see.

If the glass filters out others light except red , its fine because these people are fine with bright red light.

People with eye disorder unable to see in moderately bright light and at the same token, they can properly in dim light but not sensitive to red light.

A. In all moderately dim light in which people without the disorder can read large print, people with the disorder cannot read such print. [This is not comparison between people with disorder and people without disorder. – Eliminate it]

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.[This opposes the information given in the premise – eliminate it]

C. These people typically see more acutely at night and in dim light than do most people who do not have the disorder. [This is not comparison between people with disorder and people without disorder. – Eliminate it]

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.[when eye glasses filters out other components of bright light, it implies creating an dim environment. And if eye glass transparent to red light then this is eliminating the disorder – Hold it]

E. These people perceive colors other than red in the same way as do most people who do not have the disorder [This is not comparison between people with disorder and people without disorder. – Eliminate it]

My answer is E.
Elimination centered around choices that talked about "other people" without the disorder since the passage does not explicitly mention any limitations or advantages in these "other people".

I having difficulties understanding the statement E. With the help of POE all other options are out as the author essentially made no comparison whatsoever between "normal people" and people with this disorder. However, what exactly is the statement E saying? I don't see a connection among red component of light, other components of light and and moderately bright light.

Thanks in advance,
Jay

Dear MrSobe17,

Here goes analysis of this question:

FACT 01: Certain people unable to see in moderately bright light because::

Cells of their retinas are overwhelmed by moderately bright light

FACT 02:
These people do, however::

Show normal sensitivity to most components dim light + their retinal cells are also not excessively sensitive to red components of moderately bright light.

Argument Analysis (One line summary):
Certain people cant see in moderately bright light but can see in dim light and show normal sensitivity to red components of moderately bright light.


Analysis of answer choice E

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

As per this answer choice if people will wear eyeglass that is transparent to red component of light (will provide no issue to category of people we are discussing as they have normal sensitivity of red component) and that will filter out other components (there would not be stimulation of retinal cells), then the people would PROBABLY able to see in moderately bright light


Hope it helps!!!!

This is an inference type of question. The answer choice must be true based on the information given in the argument.

A. In all moderately dim light in which people without the disorder can read large print, people with the disorder cannot read such print.
people with disorder do not have any problems with dim light. This is irrelevant.

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.
This cannot be inferred from the argument. The argument does not state that people with disorder see better in dim light.

C. These people typically see more acutely at night and in dim light than do most people who do not have the disorder.
No, this cannot be inferred. The argument does not compare people without disorder with people with disorder. Moreover, the argument does not state that people with disorder see more acutely in dim light.

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.
Aha! The argument tells that in red components of moderately bright light do not make the retina cells more sensitive. Looks good.

E. These people perceive colors other than red in the same way as do most people who do not have the disorder
No, the argument does not compare people with/without disorder.

D.

This a tricky question for sure! The trick here is to consider people with the disorder ! You cannot compare apples to mangoes. All the other option compare people with the disorder to people without the disorder.

D correctly follows the question stem, which states "what correctly follows about the people who have only this disorder".


I got this on my GMAT Prep test and marked E. Kudos to the people who got it right in the 1st attempt

main idea here (that i will repeat in my answer explanations) is: people w/ a certain eye disorder cannot see in moderately bright light. BUT, they can see RED components of moderately bright light. What does this mean? These people w/ the disorder must not be able to see other color components in moderately bright light (i.e. blue, green, etc).

A. They typically see more acutely at night and in dim light than do most people who do not have the disorder.
can't make this comparison b/c no info is given regarding how people without the disorder see, passage only talks about people with disorder
B. They react to extremely bright light in much the sam way that people without disorder do.
same as "A"
C. In an otherwise darkened concert hall, they will see a dimly illuminated red exit sign more clearly than the people without disorder will.
same as "A"
D. The biological mechanism by which they perceive the colour red is different from the mechanism of the people who do not have this disorder.
tricky answer. we are told the cells in the retinas are overwhelmed by moderately bright light but this does NOT HAVE to be b/c of a biological mechanism. There could be some other issues at play. We don't know what specifically causes this, let's not make up some reason
E. Eyeglasses that are transparent to red components of light but filter out other components of light help these people see in moderately bright light.
MUST be true. idea here is that people w/ this disorder can see red components of moderately bright light...the "issue" is that these same people cannot see other components of moderately bright light well (i.e blue, green, etc.) by filtering out these other colors (that people w/ the disorder cannot see well), people with disorder will be able to see in moderately bright light

kudos if this was helpful :)

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.
