"Our national parks are bigger than your national parks"
Translation:Mbuga zetu za Taifa ni kubwa zaidi ya mbuga zenu
kuliko vs zaidi ya are supposed to mean exactly the same, but DT, more often than not, accepts only one of them. The problem has been reported by many of us already. I guess, we just have to continue reporting :(
And, by the way, the English translation should be "Our national parks are bigger than your parks".
