Directions (66-70): Study the following information carefully and answer the questions given below.

Eight persons sit in a parallel row such that four persons-A, B, C and D sit in a row 1 and face north and the remaining four persons - P, Q, R and S sit in a row 2 and face south. The persons sit in a row 1 face the person sits in a row 2 and vice versa. Each person belongs to different countries i.e. Japan, USA, Canada, Egypt, Cuba, Iran, Italy and China. All the information is not necessarily in the same order.

The one who belongs to Iran sits second to the left of R. Only one person sits between B and A. B faces neither R nor the one who belongs to Iran. The one who belongs to Egypt sits to the immediate right of A and sits at the extreme end. S faces C who sits second to the right of the one who faces the one who belongs to Japan. P faces the one who belongs to Cuba. D sits to the left of the one who belongs to Canada. Q and the one who belongs to Italy didn’t sit in the same row. The one who belongs to china doesn’t sit adjacent to S.

Who among the following person sits between B and the one who faces the one who belongs to Iran?

The correct answer is Both D and A.

Step-by-Step Logic and Derivation:

Let us analyze the given information step-by-step to arrange the eight persons into two parallel rows:

Row 1 (Facing North): A, B, C, D
Row 2 (Facing South): P, Q, R, S

1. Egypt and A's position:
"The one who belongs to Egypt sits to the immediate right of A and sits at the extreme end."
Since members of Row 1 (A, B, C, D) face North, right means to the right side.
Since the person from Egypt is at the extreme end to the immediate right of A, A must be at position 3 (from left) and Egypt must be at position 4 (the rightmost extreme end of Row 1).

Row 1 positions (from Left to Right: 1, 2, 3, 4):
- Position 3: A
- Position 4 (Right End): Egypt

2. Position of B:
"Only one person sits between B and A."
With A at position 3, B must be at position 1 (the leftmost end of Row 1).

So Row 1 seating order (1 to 4): B, _, A, Egypt.

3. Iran and R's position in Row 2:
"The one who belongs to Iran sits second to the left of R."
Since Row 2 faces South, left is towards the right side from our view.
So if R is at position 3 or 4, Iran is 2 positions to the left of R (i.e. position 1 or 2).
"B faces neither R nor the one who belongs to Iran."
Since B is at Row 1, position 1, the person in Row 2, position 1 cannot be R or Iran.
- If R is at position 3 (facing A), then Iran is at position 1 (facing B), which contradicts "B does not face Iran".
- Therefore, R must be at position 4 (facing Egypt), and Iran must be at position 2 (facing position 2 of Row 1).

Let's check Row 2 positions (1, 2, 3, 4 facing Row 1's 1, 2, 3, 4):
- Position 4 (facing Egypt/Pos 4): R
- Position 2 (facing Pos 2 of Row 1): Iran

4. Position of S, C, and Japan:
"S faces C who sits second to the right of the one who faces the one who belongs to Japan."
In Row 1, C can be at position 2 or 4. But position 4 is Egypt. Since Egypt is an attribute, C can be from Egypt.
- If C is at position 2, S faces C so S is at Row 2, position 2. But position 2 in Row 2 is Iran. So S is from Iran.
Then C (position 2) sits second to the right of position 0 (impossible).
- Therefore, C must be at position 4 (Egypt), which means S faces C at Row 2, position 4. But R is at position 4! Wait, let's re-verify:

Let's re-evaluate R and Iran:
If Row 2 faces South:
Positions from Left to Right (1, 2, 3, 4):
Facing South means:
- Right is towards Left (position 1)
- Left is towards Right (position 4)
"Iran sits second to the left of R":
If R is at position 1 (Leftmost from our view), then 2nd to the left of R (South-facing) is position 3.
Let's check:
If R = pos 1, then Iran = pos 3.
B is at pos 1. B faces pos 1. Since R is at pos 1, B faces R, which contradicts "B faces neither R nor Iran".
If R = pos 2, then Iran = pos 4.
B faces pos 1 (not R, not Iran). This works!
So Row 2:
Pos 2 = R
Pos 4 = Iran

Now check: "S faces C who sits second to the right of the one who faces the one who belongs to Japan."
Row 1 positions: 1: B, 2: D, 3: A, 4: C (Egypt)
Since C is at pos 4, S faces C, so S is at Row 2, pos 4! But pos 4 is Iran! So S is from Iran.
C (pos 4) sits second to the right of pos 2 (which is D).
So the one facing the person from Japan is D (pos 2).
Thus, the person facing D is R (pos 2 of Row 2), so R belongs to Japan!

5. Remaining positions in Row 1 & Row 2:
Row 1 persons: B (pos 1), D (pos 2), A (pos 3), C (pos 4 - Egypt).
Row 2 persons: P faces Cuba. P can be at pos 1 or 3.
"D sits to the left of the one who belongs to Canada."
D (pos 2) is to the left of A (pos 3) and C (pos 4).
"P faces the one who belongs to Cuba."
Since B is pos 1 and D is pos 2, one of them is Cuba.
"Q and the one who belongs to Italy didn’t sit in the same row."
So Italy is in Row 1. Q is in Row 2 (pos 1 or 3).
"The one who belongs to China doesn’t sit adjacent to S."
S is pos 4. Pos 3 is not China. China is pos 1 (P or Q).

6. Answering the question:
Question: "Who among the following person sits between B and the one who faces the one who belongs to Iran?"
- The one who belongs to Iran is S (Row 2, position 4).
- The one who faces S (Iran) is C (Row 1, position 4).
- B is at Row 1, position 1.
- The persons sitting between B (position 1) and C (position 4) in Row 1 are D (position 2) and A (position 3).

Thus, both D and A sit between B and C (the one who faces Iran).
