What this tells you
- There are 5 possibilities, so this clue alone does not decide the digits. Use crossing runs and any known cells to eliminate combinations.
- Digits in every combination: 1. Whatever the combination, the run must contain them.
- Every digit from 1 to 9 appears in at least one combination, so there is nothing to exclude outright.
