    Some Colonels are Soldiers. Some Soldiers are Politicians. No Colonel is an Officer. Conclusions: I. Some Officers can be Politicians. II. All Soldiers can be Refugees. III. Some Colonels are Politicians. IV. Some Soldiers are Colonels. In the question below there are four statements followed by four conclusions I, II, III and IV. You have to take the three given statements to be true even if they seem to be at variance from commonly known facts and then decide which of the given conclusions logically follows from the three statements disregarding commonly known facts.

    C Only conclusion IV follows. Correct Answer Incorrect Answer
    D Only conclusion I, II and IV follow. Correct Answer Incorrect Answer
    E All the conclusions follow. Correct Answer Incorrect Answer

    Solution

    Some Colonels are Soldiers (I) + Some Soldiers are Politicians (I) → Probable conclusion →   Some Politicians are Colonels (I) + No Colonel is an Officer (E) → Some Politicians are not Officers (I) → Probable conclusion → Some Officers can be Politicians (I).   Hence conclusion I follows but conclusion III does not follow. Only a few Refugees are Soldiers → All Soldiers can be Refugees (A). Hence conclusion II follows. Some Colonels are Soldiers (I) → Conversion → Some Soldiers are Colonels (I). Hence conclusion IV follows.
