Analyzing the answers, I can see that we have a lot of similar expressions, so, a lot of correct answers. Which one should be chosen as correct? I'm trying to choose the answer with apparently more research and more references, but I'm not sure about this approach.
Other example is this question with two answers (one of them is mine and I believe is right), but each one is "correct" for one region (European and Brazilian portuguese).
- It makes me think about. How others SE language sites deal with it?
- Exists some standard approach?
- This type of questions (with more than one possibility of correct answers like my examples of equivalent expressions) are not good for SE sites?
