Conclusions: I. Some Intelligent is not Handsome. II. No Honest is Smart. III. Some Handsome is Smart. IV. Some Honest is not Handsome.Solution
All Honest is Intelligent (A) → Conversion → Some Intelligent is Honest (I) + No Honest is Handsome (E) → Some Intelligent is not Handsome (O). Hence conclusion I follows. All Honest is Intelligent (A) + Some Intelligent is Smart (I) → No conclusion. Hence neither conclusion II nor III follow. No Honest is Handsome (E) → Conversion → Some Honest is not Handsome (O). Hence conclusion IV follows.
