I + I =No conclusion. Hence, conclusion I will not follow. All woods are acids (A) + No acid is a metal (E) ⇒ No wood is a metal (E) ⇒ Conversion ⇒ Some metals are not woods (O) . Hence, conclusion II follows. Some ores are woods (I) + All woods are acids (A) ⇒ Some ores are acid (I) + No acid is a metal (E) ⇒ Some ores are not metals (O).Hence, conclusion III will not follow. All woods are acids (A) ⇒ Conversion ⇒ Some acids are woods (I) ⇒ Probable conclusion ⇒ Some acids may not be woods (O). Hence, conclusion IV follow. ALTERNATE SOLUTION: Relevant Minimal Possibility:
