Statements: Only a few clouds are storms. All winds are clouds. No storm is rain. Conclusions: I. All winds are rain. II. Some winds are not rain.

Explanation

Only a few clouds→storms. All winds→clouds. No storm→rain. Winds⊂clouds. Some clouds are storms. Storms and rain are disjoint. Winds are clouds; some clouds are storms; so some winds 'might' be storms (not certain). I (All winds are rain) and II (Some winds are not rain) — since we cannot confirm any wind is a storm, we cannot confirm any wind is NOT rain either definitively. This gives either I or II.
