Which is more natural?
1) Where are you studying? - At Bristol University. - Are your parents helping you ? - Yes, they are supporting me in any way they can.
2) Where do you study? - At Bristol University. - Do your parents help you ? - Yes, they support me in any way they can.
If I were a native speaker of English, I would never shut up. :-)
"Where are you studying?" is more natural than "Where do you study?". All the other sentences are equally natural.
I'm not a teacher of English, but I have spoken it for (almost) all of my life....
