1. 

Statements: All pens are chalks. All chairs are chalks.

Conclusions:

I.  Some pens are chairs.

II. Some chalks are pens.

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 B

Explanation:

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