The kid should have asked zero if he was born or hatched.
OTOH, maybe the kid was a plant. Zero most probably asked the teacher beforehand to pick a kid to ask that question so he could answer it.
A simple yes is the only correct answer.
When people ask if I was born in San Francisco, I just say yes.
When they want to know where I was born in Oklahoma, I tell them I was born in SFO and moved to Oklahoma....
