I disagree that III. Conclusion is true. Categories 'fruits', 'vegetables' and 'pens' can be empty and it wouldn't disturb I. And II. Being truth, but if there's no 'vegetables' at all, none rains can be vegetables.

Can you reverse the SAP type premises to SIP type premises? Is it correct to reverese the statement? According to me, third conclusion is invalid. Please reply to the above confusion.
