Kiến thức về đại từ quan hệ
Tạm dịch: “For example, in advanced cities, mobile technology can assist large businesses in advanced mobility hubs for vehicles, (37)_________ significantly reduces the amount of traffic in growing cities.”
(Ví dụ, ở các thành phố tiên tiến, công nghệ di động có thể hỗ trợ các doanh nghiệp lớn trong các trung tâm di chuyển tiên tiến cho các phương tiện giao thông, cái mà giúp giảm đáng kể lưu lượng giao thông ở các thành phố đang phát triển.)

“That” chỉ dùng trong mệnh đề quan hệ xác định (không đứng sau dấu phẩy).
