Five runners—A, B, C, D, and E—finished a race. A finished before B but after C. D finished right after B. E finished before C. In what position did D finish?
Fourth
Ordering them by finish from first to last: E is before C, C is before A, A is before B, and D is right after B. The full order is E, C, A, B, D. Thus, D finished fifth? Wait, let's re-verify: E(1), C(2), A(3), B(4), D(5). Ah, D is fifth. Let's fix the answer explanation: The complete order from first to last is E, C, A, B, D. Therefore, D finished fifth.
