Which point is posterior to the ear, in a small depression one third of the distance along a curved line drawn from Yifeng SJ-17 to Jiaosun SJ-20 following the line of the rim of the ear?

Which point is posterior to the ear, in a small depression one third of the distance along a curved line drawn from Yifeng SJ-17 to Jiaosun SJ-20 following the line of the rim of the ear?

• A. SJ 19
• B. SJ 18
• C. SJ 20
• D. SJ 21

Answer: (B)

The line described runs along the rim of the ear from Yifeng to Jiaosun, and the point about one-third of the way along that curved path sits behind the ear in a small hollow. That location corresponds to SJ-18, which is positioned posterior to the ear in a shallow depression along the ear rim. This is why SJ-18 is the best fit for the description. The other points lie at different positions along or around the ear and do not occupy this one-third point on that curved line.
