If you mean this one:

for(let i = 0; i < questions.length; i++){
  let answer = prompt(`1.${questions[i][0]}`);
  if(answer === questions[i][1]){
    score++
  }
};

in the second line basically the question is been grabbed by the values inside the square brackets position i will be replaced by the loop and the 0 is the index of the question in the nested array.

Hope this helps!
