Statements: A’s @ P’s A’s % Y’s T’s # Y’s Z’s & A’s Conclusion:
I. Y’s $ Z’s
II. T’s % P’s
III. T’s ≤ Y’s

Statements: All A’s are P’s Some A’s are Y’s Only a few Y’s is T’s No Z’s is A’s Conclusions: I. All Y’s can be Z’s. II. Some T’s are P’s. III. Some Y’s are not T’s. No Z’s is A’s (E) + Some A’s are Y’s (I) → Some Y’s are nor Z’s (O) → Some Y’s can be Z’s (I).  Hence conclusion I does not follow. Some A’s are Y’s (I) → Conversion →   Some Y’s are A’s (I) + All A’s are P’s (A) → Some Y’s are P’s (I) + Only a few Y’s is T’s (I) → No conclusion. Hence conclusion II does not follow. Only a few Y’s is T’s → Some Y’s are not T’s. Hence conclusion III follows.
