II. No chair is fruit.
III. No chair is table.
IV.All chairs are windows.

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

Answer 1

The correct option is A None follows

No table is fruit. No fruit is window.
Since both the premises are negative, no definite conclusion follows.
No fruit is window. All windows are chairs.
Since the middle term 'windows' is distributed twice and one premise is negative, the conclusion must be particular negative. So, it follows that 'Some chairs are not fruits'.
