Could someone please explain to me why the following is Incorrect
a. All streets are routes of transportation.
b. None of the streets is a racing track.
Conclusion is: Some racing tracks are not routes of transportation.
I concluded the following venn diagram

Grey = impossible
So surely some tracks are routes of transport as it doesn't say that all transport routes are streets?
