15. The correct answer is (B). Each trip consists of 5 jumps, after which the glip starts
over at point X. In jumps 1–5, the first jump is to A, as the question stem tells us. In
jumps 6–10, the first jump is to B, and so on clockwise around the circuit. After 25
jumps (5 trips of 5 jumps each), the glip begins exactly the same sequence of 25 jumps
again:
Jumps 1–5: X to A to B to X to D to X
Jumps 6–10: X to B to C to X to E to X
Jumps 11–15: X to C to D to X to A to X
Jumps 16–20: X to D to E to X to B to X
Jumps 21–25: X to E to A to X to C to X
Since the pattern indicated above begins again after each multiple of 25 jumps,
jump 472 is the same as jump 22: from E to A.
