Question

    Three statements are given followed by two conclusions

    numbered I and II. 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: All Lockers are Keys. Some Keys are Doors. All Doors are Windows. Conclusions: I. Some Keys are Windows. II. Some Lockers are Doors.
    A Only conclusion II follows Correct Answer Incorrect Answer
    B Only conclusion I follows Correct Answer Incorrect Answer
    C Neither conclusion I nor II follows Correct Answer Incorrect Answer
    D Both conclusions I and II follow Correct Answer Incorrect Answer

    Solution

    Some Keys are Doors (I) + All Doors are Windows (A) → Some Keys are Windows (I). Hence conclusion I follows. All Lockers are Keys (A) + Some Keys are Doors (I) → No conclusion. Hence conclusion II does not follow.
