Official LSAT PrepTest 21, Section 3, Question 7

Postby LSAT_Padawan » Sat Mar 13, 2010 7:07 pm

This is the one about "John" and his friends sharply disagreeing about one wedding photo resembling him.

Why is the correct answer (D) It was unique in showing John's face reflected in a mirror, the photographer having taken the photograph over John's shoulder?

Why wouldn't it be either:
(A) It, unlike the other photos of John, showed him in the style of dress he and his friends usually wear rather than the formal clothes he wore at the ceremony or
(B) only photograph of John taken by the photographer in which he used a flash or
(C) It was a black-and-white photography, whereas the other photographs that showed John were mostly color photographs.

Thank you for your enlightenment!

Let's start with why the other answers are wrong. We're being asked to explain why John and his friends would disagree, NOT why the photos are different.

Answers A, B, and C explain why the photos are different from each other. But they give us no clue why John and his friends would disagree about why the one particular photo did or did not resemble him. Something about that one photo has to cause John and his friends to see or interpret it differently.

Take A. It tells us how the one photo is different, but nothing about why it would be perceived differently. In fact, they'd probably agree that the wedding photo was different from the other photos.

B is the same thing. Why would a flash photo appear to resemble John more or less to John than to his friends?

Same with C.

D is different because the photo was taken through a mirror. When John sees his own face, he typically sees it through a mirror. His friends see him without a mirror. Mirrors invert images, and people's faces are asymmetrical. Hence, a photo taken from John's perspective will resemble his view of himself, but will seem slightly off to his friends. It explains the disagreement, and so it is correct.
