Не получается автоматом брать элементы из json файла

Подскажите, пожалуйста, правильную структуру для проекта. На данный момент подгружается два списка один пустой и в него можно вводить вопросы-ответы руками и все работает но хотелось бы брать рандомные вопросы и ответы из второго или вообще без сериализации сразу из файла
