I think this sentence definitely make sense when referring to horse pawn in a chess board
stupid sentence! I guess these sentences are computer-generated, that is why they sound so weird and sometimes so rude (tera bhai ...)
When the beta was released, they stated they just wanted you to develop structures.
Now that you understand the structure you can change "ghora" to "kēla".
Most of the Duolingo courses I've tried feature some surreal sentences now and then. It's part of the fun of it for me.
in some ways, its actually better to have the weird sentence. It may help you remember it better. And like one commentor said, you can swap out nouns to make this sentence very useful.
