"Where does this street leed? " is correct and sufficient.
As a native speaker I agree
I am happy to report that "where does this street go" is also accepted.
okay, just in general markers are very confusing, but this seems confusing even for them! Why would a street have the same marker as animals do?
Also, couldn't they give us a list of the markers, at least the most common ones? Please.
The present continuous is not accepted here...
