Isn't the pronounciation of 那 and 哪 completely the same in front of 个?
As I read in the tips section of Nation, a 3rd tone only dips but doesn't rise when in front of something different than a 3rd tone. So it is, as i understand, a 2nd tone, isn't it?
It's so strange for me to see the "de" particle dangling at the end here? I'm a beginner but this strikes me as very different than the way we have been introduced to it use (something always come after, to indicate possession, location, etc)
