Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions.

The concept of obtaining fresh water from iceberg that is towed to populated areas and arid regions of the world was once treated as a joke more appropriate to cartoons than real life. But now it is being considered quite seriously by many nations, especially since scientists have warned that the human race will outgrow its fresh water supply faster than it runs out of food. Glaciers are a possible source of fresh water that has been overlooked until recently. (A)

        Three-quarters of the Earth's fresh water supply is still tied up in glacial ice, a reservoir of untapped fresh water so immense that it could sustain all the rivers of the world for 1,000 years. Floating on the oceans every year are 7,659 trillion metric tons of ice encased in 10,000 icebergs that break away from the polar ice caps, more than ninety percent of them from Antarctica. (B)

        Huge glaciers that stretch over the shallow continental shelf give birth to icebergs throughout the year. Icebergs are not like sea ice, which is formed when the sea itself freezes; rather, they are formed entirely on land, breaking off when glaciers spread over the sea. As they drift away from the polar region, icebergs sometimes move mysteriously in a direction opposite to the wind, pulled by subsurface currents. Because they melt more slowly than smaller pieces of ice, icebergs have been known to drift as far north as 35 degrees south of the equator in the Atlantic Ocean. (C)

        The difficulty arises in other technical matters, such as the prevention of rapid melting in warmer climates and the funneling of fresh water to shore in great volume. But even if the icebergs lost half of their volume in towing, the water they could provide would be far cheaper than that produced by desalination, or removing salt from water. (D)

What is the main topic of the passage?

A. The movement of glaciers 

B. Icebergs as a source of fresh water

C. Future water shortages

D. The future of the world's rivers

Dịch nghĩa: Đâu là vị trí tốt nhất để đặt câu sau:

“To corral them and steer them to parts of the world where they are needed would not be too diflicult.” - Việc dồn lại và chuyển chúng đến những vùng trên trái đất nơi mà chúng đang được cần sẽ không phải quá khó khăn.

A. (A)                             B. (B)                              C. (C)                     D. (D)

Giải thích:

Không đặt ở vị trí A vì cả đoạn một chỉ nói về quan niệm lấy nước ngọt từ băng trước và nay thay đổi như nào, không liên quan đến câu cần cho.

Không đặt ở vị tri B vì đoạn 2 nói về lượng nước ngọt nằm trong băng, không liên quan.

Không đặt ở vị trí D vì đoạn cuối nói về hiệu quả kinh tế của việc lấy nước ngọt từ băng so với các phương thức khác, không nói gì đến việc có chuyển được hay không.

Nên đặt ở vị trí C vì đoạn 3 nói về khoảng cách mà băng có thể di chuyển được, chèn thêm câu về việc chuyển băng sẽ không phải là chuyện khó khăn thì hoàn toàn hợp lí.
