Объяснение:

Когда мы меняем прямую речь на косвенную, то мы должны поменять глаголы на шаг назад в например, can - could, must - had to, found - had found, а также местоимения такие как this на that, так как вещь на которую мы указываем, может поменяться или вовсе исчезнуть с течением времени, к тому моменту когда мы о ней говорим.
