what do you often have for the lunch?

=> Lỗi sai : the -> Bỏ " the " 

Vì tên các bữa ăn như dinner , breakfast , lunch , supper thì sẽ có mạo từ  "the"ở trước nhé 

lỗi sai: does it cost to fly from HCM to Jakarta

Lí do: ở đây chúng ta hỏi cho vế "do you know " chứ ko phải "how much...." nên "how much..." ko thể chia là câu hỏi đc 

Sửa sai: how much it costs to fly from HCM to Jakarta.

P/s: Mình giải thích hơi khó hiểu chút xíu , mong bạn thông cảm . Ms lại hôm nay mình ms đọc đến nên trả lời muộn

Có gì thắc mắc ib mình nhé!

Good luck!
