Some toasters are squeezers (I) → conversion → Some squeezers are toasters (I) + All toasters is juicers (A) → Some squeezers are juicers (I). Hence conclusion I follows. Some toasters are squeezers (I) → conversion → Some squeezers are toasters (I) + All toasters are grinders (A) → Some squeezers are grinders (I). → Conversion → Some grinders are squeezers (I). Hence conclusion I follows. All toasters are grinders → conversion → Some grinders are toasters (I) + All toasters are juicers (A) → Some grinders are juicers (I). Hence conclusion III does not follow.
