Question

    In the following question below are given some

    statements followed by some conclusions based on those statements. Taking the given statements to be true even if they seem to be at variance from commonly known facts. Read all the conclusions and then decide which of the given conclusion logically follows the given statements. Statements: All Primary is Secondary. No Primary is Territory. All Territory is Level. Conclusions: I. Some Territory are not Secondary. II. Some Level being Primary is a possibility. III. Some Secondary are not Territory. IV. Some Territory are Level.
    A Only Conclusion III follows Correct Answer Incorrect Answer
    B Only Conclusions I and IV follow Correct Answer Incorrect Answer
    C Only Conclusions II, III and IV follow Correct Answer Incorrect Answer
    D Only Conclusion III follows Correct Answer Incorrect Answer

    Solution

    All Primary are Secondary (A) → Conversion → Some Secondary are Primary (I) + No Primary is Territory (E) → Some Secondary are not Territory (O). Hence conclusion I does not follow but conclusion III follows. No Primary is Territory (E) + All Territory are Level (A) → Some Level are not Primary (O*) → Probable conclusion → Some Level may be Primary (I). Hence conclusion II follows. All Territory is Level (A) → I.I. → Some Territory are Level (I). Hence conclusion IV follows.
