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.

I think you've got the relationship in statement v the wrong way round. So the statements give:

i Chases cats -> teachable
ii Plays with a kangaroo -> black nose
iii Floppy ears -> chase cats
iv Teachable -> quiet bark
v Black nose -> floppy ears

Reordering (ii, v, iii, i, iv) gives...

Play with a kangaroo -> black nose -> floppy ears -> chase cats -> teachable -> quiet bark
