Uncaught TypeError


I am trying to run the code and after the first questions pops I get an Uncaught TypeError: Cannot read property '0' of undefined.

Error is referring to the question [i][0] and I am not sure what is going on.

for( let i = 0; i < arr.length; i++){ let question = arr[i][0]; let answer = arr[i][1]; let response = prompt(question);

if(answer === response){ correctAnswers++; } }
