Объяснение:

P.s В онлайн мектепе есть опечатка. Там на втором после пробела написано Axel, хотя там должно быть написано "spoke". А сам второй пробел мы должны заполнить словом "Axel". Получиться "Professor

Axel Axel about an ancient thing he had found". Два раза повторяется. Не знаю, может только у меня так.
