Statements: Only a few Street is Path. No Way is Path. All Roads are Ways. No Road is a Footpath. Conclusion: I. Some Ways can be Streets. II. Few Roads are not Paths. III. Every Ways can never be Streets. IV. Every Footpaths can be Ways.
    A Only conclusion I, III and IV follow. Correct Answer Incorrect Answer
    B Only conclusion I and III follow. Correct Answer Incorrect Answer
    C Only conclusion I, II and IV follow. Correct Answer Incorrect Answer
    D Only conclusion I and II follow. Correct Answer Incorrect Answer
    E Only conclusion I, II and III follow. Correct Answer Incorrect Answer

    Solution

    Only a few Street is Path (I) + [No Way is a Path (E) → Conversion] → No Path is a Way (E) → Some Streets are not Ways (O) → Probable conclusion → Some Ways can be Streets (I). Hence conclusion I follows but conclusion III does not follow. All Roads are Ways (A) + No Way is a Path (E) → No Road is a Path (E) → Conversion → No Path is a Road (E) → Conversion → Some Roads are not Paths (O).Hence conclusion II follows. No Road is a Footpath(E) → Conversion →  No Footpath is a Road (E) + All Roads are Ways (A) → Some Ways are not Footpaths (O*)→ Probable conclusion → All Footpaths can be Ways (I). Hence conclusion IV follows.
