The existentialists are right about one thing: we are alone, radically alone. The proof is obvious. Suppose you were born with a physiology that permitted you to perceive only negative images, that is, you saw black where everyone else saw white and white where everyone else saw black. Nevertheless, you would learn to call what you saw as black by the name “white” because this is what you would be taught, and there would be no way that you could discover your error.
Which one of the following can be validly inferred from the statements in the argument above?
(A) Some people are born with reversed perceptions of black and white, and they cannot discover this.
(B) People with reversed perceptions of black and white would not choose their words any differently from anyone else.
(C) Existentialism is a sound philosophy, as is amply demonstrated by the physiology of color perception.
(D) The existentialists claim that some people are born with reversed perceptions of black and white.
(E) The existentialists claim that people mean different things when they use the words “black” and “white.”

A,B,D,E are all focussed on one thing difference b/w black and white.
C seems to be the best choice.

IMO B

(A) Some people are born with reversed perceptions of black and white, and they cannot discover this. --> the passage never assumes anything about "some" people being born with reversed perceptions .... the reversed preception is just an example
(B) People with reversed perceptions of black and white would not choose their words any differently from anyone else.Correct
(C) Existentialism is a sound philosophy, as is amply demonstrated by the physiology of color perception.the author never comments on the soundness of the philosophy
(D) The existentialists claim that some people are born with reversed perceptions of black and white.the existentialists never claimed that
(E) The existentialists claim that people mean different things when they use the words “black” and “white.”the existentialists never claimed this

stuck between B and D, but since there are no claims by the existentialists in the argument I'll go with B.

(B) People with reversed perceptions of black and white would not choose their words any differently from anyone else.Yes. It is kind of summary of the example
(C) Existentialism [nowhere mentioned] is a sound philosophy, as is amply demonstrated by the physiology of color perception.
(D) The existentialists claim [author is taking an example, not existentialists] that some people are born with reversed perceptions of black and white.
(E) The existentialists claim [author is taking an example, not existentialists] that people mean different things when they use the words “black” and “white.”

From the question, "you would learn to call what you saw as black by the name “white”... and there would be no way that you could discover your error." Even if you saw 'white' differently from everyone else, you'd still learn to use the word 'white' to refer to that color. You would not use different labels than other people do. That's what answer choice B says.

First I went with C, but after carefully observing :"existentialists " Vs "Existentialism", I realised that I am standing over "Shell Mine". I quickly ran towards B, and finding it better.
Whats the OA.

Existentialists :people who believe the philosophy that every individual is responsible for his or her own development
Conclusion- existentialists are right that we are alone
proof is obvious
Premise 2 - you see black where every one saw white vise versa.
premise 3- Nevertheless (meaning still) , you will call perceived black as white (since you are taught to call it white) & vice versa, and will never discover the error

To sum it up : even though you see black instead of white (as it is seen by others) , you will still call it white because this is how you are taught. This is proves that existentialist's claim that we are alone is right.

Now we have understood the argument , lets see what we can infer.
We will start weighing each choice, however we shall keep following in mind:-
1.inference shall not come straight from the argument , something must be deduced.
2.No new information is allowed.
3.We shall not infer much and shall not go a step beyond the argument.

A. Some people are born with reversed perceptions of black and white, and they cannot discover this.

Color perception is just an hypothetical example , used in the argument, to drive home the point that what we perceive might not be true. Therefore it will be wrong to infer much about the hypothesis.

B.People with reversed perceptions of black and white would not choose their words any differently from anyone else.

Very confusing , looks good , let us test every word.
It seems to be out of scope, argument clearly states that a person is taught to call some color as white or black, inferring what a person would like to call , will be going step ahead , as argument has settled the case by suggesting that person calls a color , what he or she is taught to call that color.

However choice B can be considered an assumption.

C.Existentialism is a sound philosophy, as is amply demonstrated by the physiology of color perception.

This option can be safely deduced from the the argument, since existentialists are right it can be inferred that the philosophy is also sound.

We only inferred that if believers of one philosophy are right , than the philosophy might be sound.
This is the essence of inference question , infer as little as possible.

D.The existentialists claim that some people are born with reversed perceptions of black and white.

Same problem as in case of choice A, Color perception is just an hypothetical example.
Moreover existentialists never claimed anything regarding color perception , this premise (color perception0 is introduced by author to support conclusion.

E.The existentialists claim that people mean different things when they use the words “black” and “white.”
Again existentialists never claimed any thing regarding what people perceive , it is introduced as an example to support the conclusion that existentialists are right.

IMO answer is C, hope its right
