23. 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."

这个题目的答案选B,但是我认为原文说的和B相反.能把五个选项都讲讲吗?

原文说，人是ALONE的，并且举了个例子，假如你天生看颜色都跟别人相反，白看成黑，黑看成白，但是别人教给你的是别人看到的颜色，所以一个物体是白的，别人看的也是白的，而你眼里看到的实际是黑色，但是别人教你这是白色，所以你也就认为这个物体是白色，尽管你眼里看到的是黑色。而且你永远也不会发现你的这个错误。所以B是正确的，尽管你看到的黑白颠倒，但是你仍然用白色来描述白色的东西，用黑色来描述黑色的东西。A是错误的，因为原文只是假设，并没有说确实有这样的人存在。C和D同理。E是跟原文描述的假设相反的。
