In the Riverview Building, every apartment that has a balcony also has a fireplace. None of the apartments with balconies is a one-bedroom apartment. So none of the one-bedroom apartments has a fireplace. The flawed nature of the argument above can most effectively be demonstrated by noting that, by parallel reasoning, we could conclude that
A: some cats lack fur since every dog has fur and no cat is a dog
B: every fish has fur since no cat lacks fur and no cat is a fish
C: no dog has fur since every cat has fur and no cat is a dog
D: no fish is a dog since every dog is a mammal and no fish is a mammal
Choose A, B, C or D as your solution.
