  • Question
  • Statements: Some pastries are toffees. All toffees are chocolates.

    Conclusions:

    1. Some chocolates are toffees.
    2. Some toffees are not pastries.


  • 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 I follows 

    Explanation
    Since one premise is particular, the conclusion must be particular and should not contain the middle term. Thus, it follows that 'Some pastries are chocolates', I is the converse of the second premise and so it holds. Since both the premises are affirmative, the conclusion cannot be negative. Thus, II does not follow.
