## 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

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

Here's the logical breakdown:

**Given constraints:**
- Ann did not finish first
- Beth finished immediately ahead of Ann
- Cara did not finish last

**Deduction:**

Since Beth finished immediately ahead of Ann, they occupy consecutive positions. The possible arrangements are:
- Beth 1st, Ann 2nd
- Beth 2nd, Ann 3rd

Since Ann did not finish first, the first option (Beth 1st, Ann 2nd) is consistent with the constraint.

If Beth finished 2nd and Ann finished 3rd, then Cara would have to finish 1st. But we know Cara did not finish last, which would be satisfied. However, let's check the first scenario: with Beth 1st and Ann 2nd, Cara must finish 3rd (the only remaining position), and she doesn't finish last—this works.

Testing the alternative: If Beth were 2nd and Ann 3rd, Cara would be 1st, which satisfies "Cara did not finish last." But this creates two valid solutions, which contradicts the problem's implication of a unique answer.

The unique solution that satisfies all constraints is: **Beth 1st, Ann 2nd, Cara 3rd.**

What additional information would you need to determine the race's finish times or margins?
