Sure she might be a normal 18 year old US person, quite normal, and as such, not too smart, but lets put some of you on that spot and see how coherent and clear your ramblings would be.

i bet if she was 20stone with bedraggled hair and spots your stance would be different ^_^
yes it may be difficult, but she has been trained for those kind of questions, its like saying to a comedian if the crowd gets on his/her back and he forgets his lines, thats ok because its hard.
its not ok though is it?
Sure, she might be under pressure due to the contest, but do you really think she's this genius outside of it?
I seriously doubt that, but ok, I'll give her the benefit of doubt then ^^
