Nice tongue-twister :) "Sasha was walking along the highway, sucking a bagel"?
Does шосса mean only a highway? In Polish, "szosa" means any kind of asphalt road...
Is "по шоссе" specifically "down the highway"? I wrote "on the highway" and it was marked incorrect.
They must have been three drunken friends... or is it allowed in Russia to walk along the highway?
Or if it just means road with cars, then road should be accepted. In the UK you would rather say road than highway anyway.
Still not accepted feb 2019. There's definitely no highway for Duo's improvements
