Here are some statements about puppies. Of course, you may not agree with all of them. But just suppose they were ALL correct, what conclusion could you draw from them?

(i) No puppy that chases cats is unteachable.

(ii) No puppy without a black nose will play with a Kangaroo.

(iii) Puppies with floppy ears always chase cats.

(iv) No teachable puppy has a loud bark.

(v) No puppies have black noses unless they have floppy ears.

Puppies with floppy ears have black noses. They always chase cats and do not play with kangaroos. All of these puppies are teachable unless they have loud barks.
