My solution

function createListItems(arr) { // el argumento en un array
  let items =''; // aqu'i concatenaremos los items
  for (let i=0; i < arr.length; i++ ){ // comenzamos a recorrer el array desde 0 haata arr.length
    items += `<li>${arr[i]}</li>` // cada elemento lo concatenamos en un li.
  }
  return items;
}

const quizQuestions = [
  ['raiz cuadrada de 4?', '2'],
  ['10 - 0,1 =', '0,9'],
  ['antecesor de 2', '1']
];

let score = 0;
let rightQuestions = [];
let wrongQuestions = [];


for (i = 0; i < quizQuestions.length ; i++) {
  let question = quizQuestions[i][0];
  let answer = quizQuestions[i][1]
  let response = prompt(question);
  if (response.toLowerCase() === answer) {
    rightQuestions.push(question);
    score++;
  } else {
    wrongQuestions.push(question);
  }
}

const message = `Obtuviste ${score} respuestas correctas`;

document.querySelector('main').innerHTML = `<h1>${message}</h1> <h2>You got this questions right:</h2> <ol>${createListItems(rightQuestions)}</ol>
<h2>You got this questions wrong:</h2> <ol>${createListItems(wrongQuestions)}</ol>`
