I could be wrong here, but it seems to me that a common aspect amongst all languages is the tendency to raise the pitch of your voice slightly when asking a question. Especially at the end of a question sentence.
If I’m wrong about this raised pitch being common amongst all languages, at the very least do all languages change their tone slightly to indicate that a question is being asked?
I guess there needs to be some way to indicate what is and isn’t a question. Perhaps a higher pitched voice reflects uncertainty. Is this something deep rooted in humans, or just an arbitrary choice when language developed?
The first two have emphasis that imply something different than a simple question. Like you are asking a bunch of people individually, and you are directing each question at a specific person.
The last one would maybe be like, if the person did something weird, and you were sarcastically asking where the are from, to imply that they were raised by wolves, or something like that.
Point being, yes, you can ask like that, but it has different connotations than a simple question, which I think is where you would use the rising intonation.
