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 dont agree with the solution. A puppy with a black nose may or may not play with a kangaroo. The statement (ii) only mentions that puppies who dont have black noses dont play with kangaroos. This doesnt mean that puppies with black noses DO play with kangaroos. I think thats wrong !!
A conclusion that can be drawn is
Puppies with floppy ears dont have a loud bark.
