  • Question

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

    Conclusions:

    1. Some pens are chairs.
    2. Some chalks are pens.


  • Options
  • 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

  • Correct Answer
  • Only conclusion II follows 

    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.
