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 belongs to USA?

The correct option is Q.

Step-by-Step Explanation:

Let's 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. Position of A, B, and the person from Egypt:

- "The one who belongs to Egypt sits to the immediate right of A and sits at the extreme end."

Since Row 1 faces North, immediate right means towards the right end (East).

Therefore, Egypt must be at the rightmost extreme position of Row 1 (Position 4), which means A sits at Position 3 in Row 1.

- "Only one person sits between B and A."

Since A is at Position 3, B must sit at Position 1 (the left extreme end of Row 1).

So, the arrangement of Row 1 from left to right so far is: Position 1 = B, Position 2 = ?, Position 3 = A, Position 4 = ? (Egypt).

2. Position of C and D:

- The remaining positions in Row 1 are Position 2 and Position 4.

- "S faces C who sits second to the right of the one who faces the one who belongs to Japan."

Since C is in Row 1, for C to sit second to the right of someone, C must be at Position 4 (since A is at 3 and B is at 1). Thus, C belongs to Egypt and sits at Position 4.

Consequently, the remaining person in Row 1, D, must be at Position 2.

- So, Row 1 (left to right) is: B (Pos 1), D (Pos 2), A (Pos 3), C (Pos 4, Egypt).

3. Row 2 positions (facing South):

- Since S faces C (Position 4), S is at Position 4 of Row 2 (facing C).

- "C sits second to the right of the one who faces the one who belongs to Japan."

Since C is at Position 4 in Row 1, the person who is second to the left of C in Row 1 is D (Position 2). So D faces the person from Japan.

Wait, facing North: right is towards Pos 4, left is towards Pos 1. Second to the right of Pos 2 (D) is Pos 4 (C). Therefore, the person facing D (which is Pos 2 in Row 2) belongs to Japan.

- Next, "The one who belongs to Iran sits second to the left of R."

Row 2 faces South, so "left" is towards Position 4 (right side of our view).

If R is at Position 1, then second to the left of R is Position 3. Thus, Iran is at Position 3.

If R is at Position 2, second to the left is Position 4 (which is S). But R cannot be at Pos 2 because Pos 2 faces D, and "B faces neither R nor the one who belongs to Iran" (B is at Pos 1, facing Pos 1 of Row 2). So R is NOT at Pos 1, which means B faces R? Wait, B faces Pos 1 in Row 2, so Pos 1 cannot be R or Iran.

Let's re-verify Row 2 positions (Pos 1, 2, 3, 4 from left to right of our view):

- Pos 4 of Row 2 is S.

- For "Iran sits second to the left of R" in a south-facing row (left is increasing position index: 1 -> 2 -> 3 -> 4):

R must be at Pos 1 or Pos 2. If R is at Pos 1, second to left is Pos 3 (Iran). Pos 1 faces B. But "B faces neither R nor Iran", so R CANNOT be at Pos 1!

Therefore, R must be at Pos 2 and Iran is at Pos 4 (S)!

Wait, let's check: Pos 2 is R. Second to left (South-facing, left is higher index) is Pos 4, so S belongs to Iran.

Does B (facing Pos 1) face R or Iran? No, Pos 1 is neither R nor Iran!

So in Row 2: Pos 2 = R (Japan), Pos 4 = S (Iran).

4. Placing P and Q in Row 2:

- Since Pos 2 = R and Pos 4 = S, the remaining positions in Row 2 are Pos 1 and Pos 3 for P and Q.

- "P faces the one who belongs to Cuba."

- "D sits to the left of the one who belongs to Canada."

D is at Pos 2. To sit to the left of Canada (facing North), Canada must be at Pos 3 (A) or Pos 4 (C). Since C is Egypt, A belongs to Canada.

- "Q and the one who belongs to Italy didn’t sit in the same row."

Since Q is in Row 2, the one from Italy must be in Row 1!

Row 1 countries: Pos 4 = Egypt, Pos 3 = Canada. So Italy must be at Pos 1 (B) or Pos 2 (D).

Since P faces Cuba, Cuba is in Row 1. If Cuba is Pos 1 (B), then Pos 2 (D) is Italy. If Cuba is Pos 2 (D), then Pos 1 (B) is Italy.

- "The one who belongs to China doesn’t sit adjacent to S."

S is at Pos 4 in Row 2. The person adjacent to S in Row 2 is Pos 3. So Pos 3 cannot be China.

This means China must be in Row 2 at Pos 1, or in Row 1. Since Pos 2 in Row 2 is Japan and Pos 4 is Iran, the remaining country in Row 2 (Pos 1 or Pos 3) is USA or China.

If Pos 1 of Row 2 is China, then Pos 3 must be USA. Since Pos 3 is adjacent to S (Pos 4), China at Pos 1 is NOT adjacent to S, which satisfies the condition!

Thus, Row 2 countries are: Pos 1 = China, Pos 2 = Japan, Pos 3 = USA, Pos 4 = Iran.

Since Pos 3 is USA, the person at Pos 3 in Row 2 is Q (or P). Let's check P: "P faces the one who belongs to Cuba." Cuba is at Pos 1 (B) or Pos 2 (D) in Row 1. Thus P must be at Pos 1 or Pos 2 in Row 2. But Pos 2 is R! So P must be at Pos 1 (facing B who belongs to Cuba).

Therefore, Q is at Pos 3 in Row 2, which means Q belongs to USA.

Hence, Q belongs to USA.
