Complete Question Explanation
(See the complete passage discussion here: lsat/viewtopic.php?t=12412)
The correct answer choice is (B)
The author’s discussion of the left-to-right explanation is located in the first paragraph of the passage. In lines 4-7, the author specifies that in a mirror, an image “appears reversed about the xis around which the viewer rotates his or her field of sight.” On line 10, the author continues, “...we ordinarily rotate our field of sight about a vertical axis.”
Answer choice (A): This incorrect choice refers to the other explanation of what mirrors do—the “front-to-back” explanation, rather than explaining the left-to-right reversal.
Answer choice (B): This is the correct answer choice. As discussed above, the referenced reversal is a result of the fact that our field of sight is normally rotated around a vertical axis.
Answer choice (C): The author does not suggest that the left-to-right reversal is explained by the size and position of objects reflected in the mirror, so this choice fails the Fact Test and should be eliminated from contention.
Answer choice (D): In the third paragraph the author points out that mirrors are two dimensional objects created to give the appearance of three dimensions, but this is not an explanation of the left-to-right reversal discussed in the first paragraph.
Answer choice (E): In the third paragraph the author provides that the front-to-back explanation is appealing because we are used to dealing with our mental constructs of things, but this does not explain the left-to-right reversal of objects in a mirror, so this is not the right answer to this Must Be True question.
