Q.

statements:
All birds are tall. Some tall are hens.
Conclusions:
I.Some birds are hens.
II.Some hens are tall.
                        
A. Only conclusion I follows B. Only conclusion II follows
C. Either I or II follows D. Neither I nor II follows

Answer: Option B
Explaination:

 


Since the middle term 'tall' is not distributed even once in the premises, no definite conclusion follows. However, II is the converse of the second premise and so it holds.
