Trả lời:

verified Giải bởi Vietjack

Đáp án: A. Warning → Having been warned

Giải thích: Phân từ hoàn thành “having + V (past participle)” được dùng trong mệnh đề thời gian để nhấn mạnh vào hành động diễn ra trước và khi cả hai vế đề cập đến cùng một chủ ngữ (factories). Chủ ngữ “factories” chịu tác động bởi hành động “warn” (cảnh báo) nên ta sẽ sử dụng dạng bị động của phân từ hoàn thành.

Dịch nghĩa: Having been warned about the bad effects of emissions, factories applied technology to purify them before discharging. (Được cảnh báo về việc những tác hại của khí thải, các nhà máy ứng dụng công nghệ để làm sạch chúng trước khi xả thải.)
