Đáp án D

Từ “it” ở đoạn 1 ám chỉ tới ______.

A. cách thức           B. môi trường                  C. lời nói     D. tín hiệu

Tạm dịch: “The basic function of signal is to impinge upon the environment in such a way that it attracts attention”- (Chức năng cơ bản của tín hiệu là tác động vào môi trường theo cách mà nó thu hút sự chú ý). Như vậy “it” chỉ có thể là thay thế cho “signal”.
