Q.

statements:
All roads are waters. Some waters are boats.
Conclusions:
I.Some boats are roads.
II.All waters are boats.
                        
A. Only conclusion I follows B. Only conclusion II follows
C. Either I or II follows D. Neither I nor II follows

Answer: Option D
Explaination:

 


The first premise is A type and distributes the subject. So, the middle term 'waters' which forms its predicate, is not distributed. The second premise is I type and does not distribute either subject or predicate. So, the middle term 'waters' forming its subject is not distributed. Since the middle term is not distributed even once in the premises, no definite conclusion follows
