Many times you can recognise the language even if you don't speak it, or if you do but didn't set it up as a language that you wish to receive questions in.
Ie. I can recognize german even though I don't speak it.
In my example question I would set it to spanish (now I saw that the description contains " LANG=gl_ES.UTF-8", also I've made myself sure using Google Translate).
