Five friends A, B, C, D, and E sit in a row facing north. B sits third from the left. C is not at an end. D is adjacent to C. E is immediately to the right of A. Who sits at the far left end?
Correct: C
Positioning: B is third. From left to right: positions 1,2,3,4,5. C cannot be 1 or 5. D is adjacent to C. E is right of A. If E is to the right of A (A _ E), possible positions for E are 2-5. Try A in 1: E in 2. But B (position 3) is fixed. Then C and D must fit in 4 and 5, violating adjacency. Try A in 2: E in 3 (but B occupies 3). Invalid. A in 4: E in 5. C and D must fit in 1-2. C not at end (position 1). So C in 2, D in 1. Thus, D is at far left. Correct.
