✔ Mistake: "go" should be "goes" (third person singular).

✔ Mistake: "Are they have" is incorrect. Use "Do they have" for questions in simple present.

✔ Mistake: "driving" is present participle; after "Do", use base form "drive".
🔧 Corrected: Do they usually drive to work?

15. He doesn't often drinks coffe.
✔ Mistake: Two errors: "drinks" → "drink" (after "doesn't", use base form), and "coffe" → "coffee" (spelling).
But since only one mistake per sentence is allowed, focus on grammar:
🔧 Corrected: He doesn't often drink coffee.
*(Note: "coffe" → "coffee" is spelling, so grammar fix is "drink")*
