    Question

    Three statements are given followed by three

    conclusions numbered I, II and III. Assuming the statements to be true, even if they seem to be at variance with commonly known facts, decide which of the conclusions logically follow(s) from the statements. Statements: Some drivers are tools. Some tools are screws. All screws are garages. Conclusions: I. All drivers can never be garages. II. Some tools are garages. III. All drivers being screws is a possibility.
    A Both conclusions I and II follow Correct Answer Incorrect Answer
    B Only conclusion I follows Correct Answer Incorrect Answer
    C Only conclusion III follows Correct Answer Incorrect Answer
    D Both conclusions II and III follow Correct Answer Incorrect Answer

    Solution

    Some tools are screws (I) + All screws are garages (A) → Some tools are garages (I) → Conversion → Some garages are tools (I) + Some tools are drivers (I) → No conclusion. Hence conclusion I does not follow. Some tools are screws (I) + All screws are garages (A) → Some tools are garages (I). Hence conclusion II follows. Some drivers are tools (I) + Some tools are screws (I) → Probable conclusion →  All drivers may be screws (A). Hence conclusion III follows.
