Translation:What does he say?
It told me that "What did he say?" is a correct solution. Wouldn't that be 他说了什么？
You don't have to mark the past in Chinese like you do in English, as context makes it clear usually. What does he say/ what did he say are both correct.
You don't have to use past tense in Chinese like you do in English, as the text makes it clear usually. "What does he say" AND "What did he say" are both correct. :)
I tried 'what is she saying?' And they said it was incorrect. Can anyone tell me why?
To add to Kim765719's reply, the first part of 她 (she) means woman (女). If you can remember that, it is easy to tell the difference between 他 and 她.
Though he and she are both pronounced the same, ta, The characters are slightly different. I'm sorry, I don't have a Chinese keyboard right now to show you the difference.
I am still having trouble with "什么" vs "吗." Perhaps "什么" always requests a direct object?
