# RE6 | anthropic/claude-opus-5 | run 2

## Prompt

Ann, Beth, and Cara finished a race in distinct positions. Ann did not finish first. Beth finished immediately ahead of Ann. Cara did not finish last. Who finished in each position?

## Response

**Cara finished first, Beth second, and Ann third.**

## Reasoning

**Step 1 — Apply the "immediately ahead" clue.**
Beth must occupy the position directly before Ann, so the only possible pairings are Beth 1st/Ann 2nd, or Beth 2nd/Ann 3rd.

**Step 2 — Test the first option.**
If Beth is 1st and Ann is 2nd, Cara must be 3rd (last). That contradicts the clue that Cara did not finish last, so this arrangement is eliminated.

**Step 3 — Test the second option.**
If Beth is 2nd and Ann is 3rd, Cara takes 1st place. This satisfies every condition: Ann isn't first, Beth is immediately ahead of Ann, and Cara isn't last.

## Final Standings

| Position | Runner |
|---|---|
| 1st | Cara |
| 2nd | Beth |
| 3rd | Ann |

Note that the clue "Ann did not finish first" is redundant here — it's already guaranteed by Beth finishing ahead of her.
