Question

Ten persons are seated in two parallel rows with five persons in each row, equally spaced. In the first row, P, Q, R, S, and T sit facing south, while in the second row, A, B, C, D, and E sit facing north. Each person in one row faces exactly one person in the opposite row. Who are seated exactly in the middle positions of their respective rows?

Given:

I. D sits third to the left of A. P faces an immediate neighbor of D. R sits second to the right of P, and E sits immediately to the right of D.

II. Only one person sits between Q and S. B and E are immediate neighbors.

Accepted Answer

**Solution:**

1. From statement I:
   - D is third to the left of A.
   - P faces an immediate neighbor of D.
   - R is second to the right of P.
   - E sits immediately to the right of D.

This gives partial information about the positions but does not fully determine the middle seats.

2. From statement II:
   - Only one person sits between Q and S.
   - B and E are immediate neighbors.

This also provides some relative seating but is insufficient alone to identify the middle positions.

3. Combining both statements:
   - Even together, the information does not conclusively identify who sits exactly in the middle of each row.

Therefore, the given statements together do not provide enough data to answer the question definitively.

**Answer:** (c) Both statements I and II together are not sufficient.
