To help my students get ready for RSE in English, I go to the official site of the exam and take some materials from there.
Here's a grammar task that makes my feel at a loss.
The story goes about a seagull that was adopted by a man...
He slept in a cat’s basket, from which he acquired a taste for Whiskas. Since then, Mr. Pooh has learned the sound of the fridge door opening.
He __________________ (LEAVE) the family home, but he can’t resist returning three times a day for his favourite food, announcing his arrival by tapping on the door.
The answer is Past Simple, that is LEFT, but to me there should be Present Perfect. I think so because the actions in the sentence are related to the present.
Would it be relevant to use Present Perfect to underline that eventually the seagull has left the family, but (now) he can't resist visiting the family and (still) sees them for his favourite food?
