In English, "or" can used used in the sense of having a choice （Chicken or beef?), and as an "either or" statement (it doesn't matter if you're black or white). In Chinese, "或者"(huòzhě) is used for the latter.

Structure:
Whilst "还是" is used for "or" in questions, "或者" is used for "or" in statements.
