Some caps are covers (I) ⇒ conversion⇒ Some covers are caps (I) + No cap is a cup (E) ⇒ Some covers are not cups (O). Hence conclusion I does not follow. Some caps are covers (I) +All covers are glasses (A) ⇒ Some caps are glasses (I) ⇒ conversion⇒ Some glasses are caps (I). Hence conclusion II follows. Some caps are covers (I) ⇒ conversion⇒ Some covers are caps (I). Hence conclusion III follows.
