Read the given information carefully and answer the question that follows.

Five friends P, Q, R, S, and T are standing in a single row facing north. T is standing directly between R and P. S is located to the immediate left of R. Q is standing at the right end of the line. Who is standing in the middle of the row?

The correct answer is T.

Let us break down the logical reasoning step-by-step to determine the seating arrangement of the five friends (P, Q, R, S, and T) facing north.

Step 1: Understand the direction and total positions
Since all friends are facing north, their left aligns with our left, and their right aligns with our right.
There are 5 positions in a single row, numbered 1 to 5 from left to right:
Position: [1] [2] [3] [4] [5]

Step 2: Fix the position of Q
We are given that Q is standing at the right end of the line.
Therefore, Q occupies position 5:
Arrangement: _ , _ , _ , _ , Q

Step 3: Analyze the relationship between R, T, and P
We are told that T is standing directly between R and P. This means R, T, and P form a continuous group in either the order R - T - P or P - T - R.

Step 4: Analyze the position of S relative to R
We are given that S is located to the immediate left of R.
This implies S must be placed directly before R (S - R).
Combining this with the group from Step 3, S must be immediately to the left of R, which forces the sequence to be S - R - T - P.

Step 5: Complete the final arrangement
Placing the four-member sequence (S - R - T - P) into the remaining available positions (1 to 4), we get:
Position 1 (Left end): S
Position 2: R
Position 3 (Middle): T
Position 4: P
Position 5 (Right end): Q

Final Order: S - R - T - P - Q

Thus, the friend standing in the middle of the row (3rd position) is T.
