What is the difference in grammar and meaning between these two sentences?
1: The book that he borrowed is in his room.
2: The book that he has borrowed is in his room.
I personally think, which I might be wrong, that the first sentence is talking about simple past and it implies on he borrowed the book in past. The latter one is talking about present perfect and it implies on a thing that started in the past and it's still happening until. So he borrowed the book in the past and he still has it.
I don't know if I'm wrong or not.
