    Let "creatures" be Universe; ${\displaystyle m}$ = "teetotalers"; ${\displaystyle x}$ = "that like sugar"; ${\displaystyle y}$ = "nightingales".

    All ${\displaystyle m}$ are ${\displaystyle x}$; No ${\displaystyle y}$ are ${\displaystyle m^{\prime }}$.	${\displaystyle \scriptstyle {\left.{\begin{matrix}\ \\\ \end{matrix}}\right\}\,}}$	∴ No ${\displaystyle y}$ are ${\displaystyle m^{\prime }}$.

    i.e. No nightingales dislike sugar.

    Let "food" be Universe; ${\displaystyle m}$ = "wholesome"; ${\displaystyle x}$ = "muffins"; ${\displaystyle y}$ = "buns".

    No ${\displaystyle x}$ are ${\displaystyle m}$; All ${\displaystyle y}$ are ${\displaystyle m}$.	${\displaystyle \scriptstyle {\left.{\begin{matrix}\ \\\ \end{matrix}}\right\}\,}}$

    There is 'no information' for the smaller Diagram; so no Conclusion can be drawn.
