she didn't win 13 VMAs in 2010, she was nominated for 13 VMAs - she won 1 for Telephone and 7 for Bad Romance making a total of 8 VMAs won, not 13 - also if you accept Born This Way Ball, you should also accept Monster Ball (without the "tour")
That's actually not all of them; that's just the ones she uses legally. She has four middle names, think yourself lucky the quiz maker doesn't know them all.
