1. She returned me the book … I gave her yesterday.

2. Do you know the student … has won the first prize in the competition?

3. The mother tongue is a language … a child learns naturally, in his/ her family.

4. I knew a lady … played tennis every day.

5. Kate found a bag … she liked.

что?

3 у тебя верно, у нас же привязка идет к одушевленное или неодушевленное, language - нет, соответственно, твой вариант правильный. 

спасибо
