I put: He is either sleeping, or he can't hear us. I'm not a native English speaker, so I wonder: should this be accepted, or is it wrong?.
As a native speaker I also typed in that but it was wrong . I guess because of the uz for already.
Why ios wrong Either he already sleeps or he does not hear us
it is grammatically incorrect. it is an ongoing situation and needs the ing form.
How do you determine when to ya Nebo vs Anebo?
It does not matter which one you use, they are interchangeable.
