This thread is resolved. Here is a description of the problem and solution.
I don't know how/where to translate the quiz created using Advisor Quiz.
I can see that you're using shortcodes to display the quiz in the front-end, using Elementor. In this case, what you can do is create a new quiz for English and when adding the translation for the page where you are using the quiz.
Just simply add the shortcode for the English quiz (please see the attached screenshot). On the left, you have the shortcode for the Italian quiz and on the right, you can add the shortcode for the English quiz. This way you will see the English quiz on the translated page.
