Conclusions:
Since one premise is particular and the other negative, the conclusion must be particular negative and should not contain the middle term. So, it follows that 'Some trains are not jungles'.
No road is jungle. All flowers are jungles.
Since both the premises are universal and one premise is negative, the conclusion must be universal negative and should not contain the middle term. So, it follows that 'No flower is road'. IV is the converse of this conclusion and so it holds.
Some trains are roads, No flower is road.
As discussed above, it follows that 'Some trains are not flowers'.
