It seems like you're missing a "," after your first item in the first array "questions".

var questions = [
  ['How many states are in the United States?',50]
  ['How many continents are there?', 24],
  ['How many legs does and insect have?', 6,]
];

Should be

var questions = [
  ['How many states are in the United States?', 50],
  ['How many continents are there?', 24],
  ['How many legs does and insect have?', 6]
];

I hope this helps.
