Я пытаюсь создать тест, но после стартовой страницы не уверен, как отобразить варианты ответа. Я создал кнопки для выбора в html и запустил их как скрытые, и выделил для них в javascript. У меня есть вопросы и ответы в массиве, но я застрял при отображении кнопок выбора под вопросом. После начальной стартовой страницы.
