Why is B the answer? None of the options actually seem like right answers.

Why is B the answer? None of the options actually seem like right answers.

Check the stimulus carefully once again...

Quote:
It is hypothesized that children with a special condition called Colourshift syndrome have different perceptions of color than ordinary children - these special children perceive the ordinarily perceived red as green and the ordinarily perceived green as yellow. A particular child was given a real red rose with green leaves and was asked to draw it using coloring pencils. The child drew a green rose with yellow leaves. From this drawing, it was concluded that the child must be one of those special ones with Colourshift syndrome.

Now, check carefully, only option (B) is within the scope of the arguement, rest all are out of scope and diverts from the topic.

Think that E is a better answer.
If The children with Colourshift syndrome see the colors of the paints or pencils they use to draw the same way they see the colors of other real-life objects, wouldn't it make the argument more strong. How does it indicate a flaw in the argument?

It is hypothesized that children with a special condition called Colourshift syndrome have different perceptions of color than ordinary children - these special children perceive the ordinarily perceived red as green and the ordinarily perceived green as yellow. A particular child was given a real red rose with green leaves and was asked to draw it using coloring pencils. The child drew a green rose with yellow leaves. From this drawing, it was concluded that the child must be one of those special ones with Colourshift syndrome.

If the hypothesis about Colourshift syndrome mentioned in the above passage is true, then which one of the following, if also true, indicates the flaw in the above conclusion?


A. When asked to draw a red rose with green leaves, some children drew a green rose with red leaves.
B. The children with Colourshift syndrome see the colors of the paints or pencils they use to draw the same way they see the colors of other real-life objects.
C. Colourshift syndrome is acquired only by birth.
D. The child had color blindness and could not distinguish blue from green.
E. In some children's storybooks, the colors of some objects portrayed are different from the colors of those objects in real life.

Official Solution:


It is hypothesized that children with a special condition called Colourshift syndrome have different perceptions of color than ordinary children - these special children perceive the ordinarily perceived red as green and the ordinarily perceived green as yellow. A particular child was given a real red rose with green leaves and was asked to draw it using coloring pencils. The child drew a green rose with yellow leaves. From this drawing, it was concluded that the child must be one of those special ones with Colourshift syndrome.

If the hypothesis about Colourshift syndrome mentioned in the above passage is true, then which one of the following, if also true, indicates the flaw in the above conclusion?


A. When asked to draw a red rose with green leaves, some children drew a green rose with red leaves.
B. The children with Colourshift syndrome see the colors of the paints or pencils they use to draw the same way they see the colors of other real-life objects.
C. Colourshift syndrome is acquired only by birth.
D. The child had color blindness and could not distinguish blue from green.
E. In some children's storybooks, the colors of some objects portrayed are different from the colors of those objects in real life.


A. This option is not relevant to the flaw in the conclusion. It just provides an example of what some other children drew, without addressing whether the child in question has Colourshift syndrome or not.

B CORRECT. This option is correct. If this is true, then the child would perceive the red coloring pencil as a green pencil and the green coloring pencil as a yellow pencil. Thus, he would still draw the red rose (which he sees as green) with the red pencil (which he sees as green) and the green leaves (which he sees as yellow) with the green pencil (which he sees as yellow). The resulting drawing would still depict a red rose with green leaves, not a green rose with yellow leaves. This option explains the flaw in the conclusion.

C. This option is not relevant to the flaw in the conclusion. It simply provides information about how Colourshift syndrome is acquired, without addressing the validity of the conclusion itself.

D. This option is irrelevant to the Colourshift syndrome and the specific colors involved in the hypothesis. The hypothesis discusses the perception of red as green and green as yellow. If the child had color blindness and was unable to distinguish blue from green, he would have mistaken green for blue, not yellow. Therefore, this option does not address the flaw in the conclusion related to Colourshift syndrome.

E. This option does not reflect a flaw in the argument as such. The child was not asked to draw something from a storybook, but he was given a real red rose with green leaves to draw.
