No wire is pole.
Some poles are irons .
Conclusions:
I. No pole is a wire.
II. Some irons are not wires.
III. Some chalks are iron.
No wire is a pole (E) ⇒ Conversion ⇒ No pole is a wire (E). Hence conclusion I follow. No wire is pole(E) + Some poles are irons (I) ⇒ Some irons are not wires(O*). Hence conclusion II follows. Some chalks are wires(I) + No wire is pole(E) ⇒ Some chalks are not poles (O) + Some poles are irons(I) ⇒ No conclusion. Hence conclusion III does not follow.
