Statements :Some pastries are toffees. All toffees are chocolates.

Conclusions :
I. Some chocolates are toffees.
II. Some toffees are not pastries.

Explanation:-

Since one premise is particular, the conclusion must be particular and should not contain the middle term. Thus, it follows that 'Some pastries are chocolates', I is the converse of the second premise and so it holds. Since both the premises are affirmative, the conclusion cannot be negative. Thus, II does not follow.
