Обоснование:
В данном задании требуется заменить выделенные части предложений с использованием притяжательных местоимений.

Пример обоснования для первого предложения:
Изначально в предложении даны две девушки, принадлежащие разным людям. Некоторый человек хочет получить свою девушку, а не девушку другого человека, поэтому он говорит "I want my girlfriend, not his girlfriend". Затем для краткости вместо "my girlfriend" используется местоимение "mine".

Постепенное решение:
- В предложении даны две девушки: "This is my girlfriend and that’s his girlfriend".
- Нужно выразить желание получить свою девушку: "I want my girlfriend, not his girlfriend".
- Заменяем "my girlfriend" на местоимение "mine": "I want mine, not his".
