A. khi sinh vật đầu tiên bị ảnh hưởng.
B. ngay sau khi sự cân bằng tự nhiên bị phá hủy.
C. khi chất độc bị đổ xuống nguồn nước.
D. khi nhiều loài cá và chim bị chết.
Dẫn chứng câu 3-5 đoạn 1: “Very often the effects of pollution are not noticed for many months or years because the first organisms to be affected are either plants or plankton. But these organisms are the food of fish and birds and other creatures. When this food disappears, the fish and birds die in this way a whole food chain can be wiped out, and it is not until dead fish and water birds are seen at the river’s edge or on the sea shore that people realize what is happening” – (Những tác động thường xuyên của ô nhiễm không được chú ý tới trong vài tháng, thậm chí là vài năm bởi sinh vật đầu tiên bị ảnh hưởng chỉ là các loài thực vật hoặc các sinh vật phù du. Nhưng đối với những sinh vật làm thức ăn cho cá, chim hoặc và loài sinh vật khác. Khi chúng biến mất thì cá, chim cũng chết theo như cách mà 1 chuỗi thức ăn bị xóa sổ, và cho đến khi xác chết chim, cá được nhìn thấy trên mặt hồ hoặc bờ biển thì con người mới nhận thức được rằng điều gì đang xảy ra).
