Miss Philippines Venus Raj: What is one big mistake you've made and what did you do to make it right? She says she hasn't made any major mistakes, then gives a shout-out to her family. "Thank you so much that I am here."
I am of the opinion that this is an assassination question. If someone asks you this question there is no right answer. Really, there isn't. First, the question assumes facts that aren't in evidence, namely that the contestant has committed some big mistake (in fact, it assumes plural big mistakes if you read into it more). And then it asks the contestant to share that potentially embarrassing mistake with strangers.
This is the part of the contest where the woman is allowed to show that she is more than just a pretty face, and has a good head on her shoulders, and yet one judge saw fit to ask a question exploiting the contestant's personal life, as if this is Jersey Shore.
That said, there is a reason why rational people don't give a shit about this stupid stuff. It's on the same level as Movie and TV award shows - for complete fucking retards only.
