Statements: All Hills are Mountains. Some Road are Rivers. No Hill is River. Conclusion: I. No Mountain is River. II. No Hill is Road. III. Some Mountains are Hills.Solution
All Hills are Mountains (A) → Conversion → Some Mountains are Hills (I) + No Hill is River (E) → Some Mountains are not Rivers (O). Hence conclusion I does not follow. No Hill is River (E) + Some Rivers are Road (I) → Some Road are not Hills (O*). Hence conclusion II does not follow. All Hills are Mountains (A) → Conversion → Some Mountains are Hills (I). Hence conclusion III follows.
