All Speak is Read (A) + No Read is Walk (E) → No Speak is Walk (E) → Conversion → Some Speak is not Walk (O). Hence conclusion I follows. Some Read is Write (I) → Conversion → Some Write is Read (I) + No Read is Walk (E) → Some Write is not Walk (O). Hence conclusion II does not follow. All Speak is Read (A) + Some Read is Write (I) → No conclusion. Hence conclusion III does not follow.
