Объяснение:

Привет. Надеюсь, что тебе. Смотри, в №3(2) мне не очень понятен смысл: бежать в прямом смысле или просто торопиться. Если это торопиться, тогда напиши We don't have to hurry. Я ещё не уверена в №3(5), ибо should– это следовало бы, must – обязан(по правилам),can –мочь/уметь, could – мог бы, have to – приходится делать что.л. Написала, как думаю я. Если будут вопросы, пиши в комменты. Удачи;)
