Other factor is literacy of population. It seems to me, that formulated question is nut suitable for outlined problem.

Thank you Dr Jarosalv for adding answer to my simple question. Yes, there are contextual and situational factors. I would be grateful if you can recommend papers published in this area.

There are some papers on this problems, e.g.
