Câu hỏi :
Read the following passage and mark the letter A, B, C or D on your answer sheet to indicate the correct word for each of the blanks from 36 to 40.
Carbon dioxide in the atmosphere, which is primarily a result of mankind's burning of fuels, is thought to act like the glass of a greenhouse. It absorbs heat radiation from the earth and its atmosphere, heats that otherwise would dissipate into space. The possibility that the greenhouse effect could alter the earth's temperature has been debated for many years. Scientists have agreed that carbon dioxide is increasing but there has been uncertainty about whether temperatures are also increasing. The major difficulty in accepting the greenhouse effect has been the absence of observed warming coincident with the historic carbon dioxide increase.

Nghi ngờ về hiệu ứng nhà kính dường như tập trung vào thực tế là __________.
A. sự gia tăng về khối lượng CO2 và nhiệt độ toàn cầu thường không tương ứng với nhau
B. rất khó xác định vị trí và định dạng carbon dioxide trong khí quyển
C. tăng trưởng sản xuất trong nhà kính chỉ mang lại lợi nhuận không đáng kể
D. Trái Đất đang dần nguội lạnh
Thông tin: The major difficulty in accepting the greenhouse effect has been the absence of observed warming coincident with the historic carbon dioxide increase.
Tạm dịch: Khó khăn lớn trong việc chấp nhận hiệu ứng nhà kính là thiếu sự quan sát ấm lên trùng hợp với sự gia tăng CO2 trong lịch sử.
