In a world inhabited exclusively by shapelife, cosmic collisions have contaminated the hydrosphere with extracranial toxicity. The following three statements are true:
Rhombicosi are non-toxic.
No shapelife is a Dodecahedron who can see the fifth dimension.
Non-toxic shapelifers are Dodecahedra.
Which of the following statements are true?
Dodecahedra are Rhombicosi.
Some Rhombicosi can see the fifth dimension.
A shapelife who cannot see the fifth dimension is toxic.
No Rhombicosi can see the fifth dimension.
Solution
From the Venn diagram, we see that only statement d is true.
