Concept:This is a vertical arrangement puzzle; a statement is sufficient only when it fixes the position of T and clearly gives the box two places below it.
Explanation:We need to find which box is placed two boxes below T.
Only the statement that gives one definite box is sufficient.
Statement I: V is below U and two boxes are placed between U and V.
Possible bottom-to-top pairs for
(V,U) are
(1,4) and
(2,5).
Q is above U, and T is exactly between Q and V.
For
(V,U)=(1,4), Q must be at position 5, so T is exactly between positions 1 and 5, giving T at position 3.
For
(V,U)=(2,5), Q must be at position 6, so T is exactly between positions 2 and 6, giving T at position 4.
In both valid cases, the box two places below T is V.
Therefore, Statement I alone is sufficient.
Statement II: Three boxes are placed between U and S, and S is below U, so possible
(S,U) pairs are
(1,5) and
(2,6).
T is adjacent to U, and R is just below T.
For
(S,U)=(1,5), T is at position 4 and R is at position 3; the remaining positions give V at 2 and Q at 6, so the box two places below T is V.
For
(S,U)=(2,6), T is at position 5 and R is at position 4; the remaining positions give V at 1 and Q at 3, so the box two places below T is Q.
Statement II leads to two different possibilities, so it is not sufficient.
Hence, only Statement I alone answers the question.
Answer:Option D: The data in Statement I alone is sufficient to answer the question, while the data in Statement II alone is not sufficient to answer the question.
