Show answer & explanation
Answer: (C) D
Explanation
Y is at the right end (position 7). I is fifth to the left of Y, so I is at 2, and T, two to the right of I, is at 4. S, O and R must fit as S, _, O, R with R three to the right of S; the only free slots are 3, 5, 6, so S = 3, O = 5, R = 6, and H takes position 1. The row is H I S T O R Y. The middle person (4th) is T, and the person to T's right is O.
