Câu 1, hành động finish her dinner xảy ra trước hành động learn her lesson nên em chia quá khứ hoàn thành cho vế sau là ko hợp lý. Quá khứ hoàn thành sẽ đc dùng cho một hành động kết thúc trước một hành động khác trong quá khứ, không đúng trong trường hợp này.
Câu 5. hai hành động xảy ra đồng thời, song song với nhau. Vì thế vế sau chia quá khứ đơn chưa đúng.
