Lesson 4 HW, Game #4, question 19

[jostomel]

Can you explain why D is not correct. I understand how the book explanation got to A, Family cars on 1, but don't the inferences show that Sports cars must also be on floor 3 (e)? The book doesn't do a very good job describing this problem, maybe you can shed some light on it.

Hi jostomel,

Thanks for the question! The key here is that there do not HAVE to be sports cars; it is possible that each floor has family cars, including the third floor. Does that make sense?

[jostomel]

Yes that makes sense, I was assuming that both sports and family cars had to be present in the game. thanks
