Should also accept "Please, show me this yellow scarf", as it is more natural to say it in that order in English
Right now the more natural order is set as default.
This weird one is accepted because from the technical point of view it's grammatically correct.
But please, to those of you translating the Ukrainian sentence too literally, word for word, this is not natural in English! Please use "Please, show me ..." or "Show me ..., please" instead.
