Statements: Some hens are cows. All cows are horses.

Conclusions:

I.  Some horses are hens.

II. Some hens are horses.

A. Only conclusion I follows
B. Only conclusion II follows
C. Either I or II follows
D. Neither I nor II follows
E. Both I and II follow

Answer: Option E

Explanation:

Since one premise is particular, the conclusion must be particular and should not contain the middle term. So, II follows. I is the converse of II and so it also holds.
