Some monitors are scanners (I) + All scanners are laptops (A) → Some monitors are laptops (I) → Conversion → Some laptops are monitors (I). Hence conclusion I follows. Some printers are students (I) + No student is monitor (E) → Some printers are not monitors (O). Hence conclusion II follows. All scanners are laptops (A) → Conversion → Some laptops are scanners (I). Hence conclusion III follows.
