Mặt Trăng có màu gì tối nay
I put the same and got zapped (Nov 30, 2020)
"Mặt trăng màu gì tối này?", - not accepted. Does the question have to go at the end of the sentence, always?
Why does this lesson keep capitalizing the first letter of the celestial bodies, aka the Sun and the Moon, as if they are characters in a story? The sun is a giant ball of burning gas and the moon is a giant spherical rock mirror.
I can't speak for the Vietnamese, but in English we capitalize proper nouns.
How about "Màu của Mặt Trăng tôi nay là gì"?
How about "Mặt Trăng là (có?) màu gì tối này"?
