  • Question
  • Statements: All dolls are windows. All bottles are windows. All cars are bottles.

    Conclusions:

    1. All cars are windows.
    2. Some cars are dolls.
    3. Some windows are cars.


  • Options
  • A. Only I and II follow
  • B. Only II and III follow
  • C. Only I and III follow
  • D. All follow
  • E. None of these

  • Correct Answer
  • Only I and III follow 

    Explanation
    All cars are bottles. All bottles are windows.

    Since both the premises are universal, the conclusion must be universal and shouldn't contain the middle term, So, it follows that 'All cars are windows'. Thus, I follows.

    Also, III is the converse of this conclusion and so it holds.

    All dolls are windows. All bottles are windows.

    Since the middle term 'windows' is not distributed even once in the premises, no definite conclusion follows.

    All cars are windows. All bottles are windows.

    Again, the middle term 'windows' is not distributed even once in the premises.

    So, no definite conclusion follows.
