If all plinks are plonks and some plunks are plinks, which of these statements must be true?
X: All plinks are plunks.
Y: Some plonks are plunks.
Z: Some plinks are not plunks.
Source: Crux Mathematicorum, 2004:
The truthfulness of the declarations X and Z are indeterminate.
Some plunks are plinks, and since all plinks are plonks, some plunks are plonks (Y).
