They're accepted now, but unfortunately it takes some time for the changes we make in the Incubator to be active for users (sometimes as long as two weeks).
Still, please report (with the button in the lesson, not in the discussion) if it's not accepted, it's still possible something got missed!
I was confused that the sentence didn't include 'the girl '. Found a website that checks sentences to show what is more commonly used. According to TextRanch, "the boy and girl" is used twice as much as "the boy and the girl." https://textranch.com/58592/the-boy-and-girl/or/the-boy-and-the-girl/
