Проверь еще раз: "Yet" и "already" часто указывают на Present Perfect, а конкретное время в прошлом (например, "in May") – на Past Simple.

Уровень Эксперт: В 18 предложении используется Past Perfect, так как действие (переезд и нахождение там два года) произошло до определенного момента в прошлом (до Рождества).
