Statements :
All sparrows are parrots.
No parrot is bird.
All birds are peacocks.
Conclusions:
I. Some birds are not parrots.
II. Some peacocks are not parrots.
No parrot is bird (E) ⇒ Conversion ⇒ No bird is a parrot (E). ⇒ I.I. ⇒ Some birds are not parrots (O). Hence, conclusion I will follow. No parrot is a bird (E) + All birds are peacocks (A) = Some peacocks are not parrots (O*). Hence, conclusion II will also follow.
