No triangle is a cuboid(E) + Some cuboids are pentagons(I) ⇒ Some pentagons are not triangles(O*). Hence conclusion I does not follow. All hexagons are cuboids(A) ⇒ I.I ⇒ Some hexagons are cuboids(I). Hence conclusion II does not follow. Some cuboids are pentagons(I) ⇒ Conversion ⇒ Some pentagons are cuboids(I). Hence conclusion III follows.
