    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: All PR are OL All OL are RT Some RT are UE Conclusions: I. Some OL are UE. II. All PR are RT. III. Some RT are not PR.
    A Only conclusion II follows Correct Answer Incorrect Answer
    B Only conclusions I and III follow Correct Answer Incorrect Answer
    C All of the conclusions follow Correct Answer Incorrect Answer
    D Only conclusions I and II follow Correct Answer Incorrect Answer

    Solution

    All OL are RT  (A) + Some RT are UE (I) → No conclusion. Hence conclusion I does not follow. All PR are OL (A) + All OL are RT (A) → All PR are RT (A). Hence conclusion II follows but conclusion III does not follow.
