"She writes about that staff" is not correct, "that" can not precede a plural or collective noun. "She writes about the staff" is correct.

Saya pakai "the staff" malah salah
Yang ngerti tolong jelasin
Kenapa pakai "that" bukan pakai "the"

They are not each time in the same order, so we don't know which is the 3rd.
Bangai mana cara membedakan saat memakai kata she her sama he
Bukannya di segment lain bisa pake the?
