Because it's the first year breakdancing was in the Olympics and I doubt many people knew about it or how to qualify.It's so weird she even qualified. I mean HOW?
The other stuff these guys say about breakdance is just utter rubbish. It's so unbelievably challenging in the he highest level. Not many athletes in other events couldn't pull off the stress that breaking puts on wrists, elbows and shoulders especially.
Qualifying for these events can be really laborious. Like the 3 on 3 basketball thing. You can't just send whoever you want, the team actually has to go to these different qualifying events throughout the year(s) and qualify through placing in tournaments.
