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

Alaska is disappearing slowly, but surely. It is estimated that since the 1950s, as much as fifteen percent of Alaska's land area has disappeared. How can a whole state be disappearing? The problem is that Alaska’s glaciers are melting. The state has more than 100,000 glaciers. These glaciers account for about 75,000 square kilometers, or five percent, of the state’s area. That is an area of land larger than Ireland!

According to a recent report by the US Geological Survey, ninety-nine percent of Alaska's glaciers are either retreating or diminishing. This diminishing seems mainly due to the increase in global temperatures. Since the 19605, the average year-round temperature has increased by almost 3°C. Additionally, the average winter temperature has increased by over 6°C. Presently, an estimated 100 cubic kilometers of ice is disappearing from Alaskan glaciers every year. It may be even more in the near future, as some scientists predict that the average world temperature could go up 4 to 7°C by the year 2100.

Another problem facing Alaska is its thawing permafrost. Much of the land in Alaska used to be permanently frozen or frozen for most of the year. Now, the thawing permafrost is causing a number of problems for people living in Alaska. Roads and utility poles are collapsing as the ground around and under them warms and soften. Also, the hard permafrost that originally prevented beaches from eroding during violent storms is now melting. People who live along Alaska's coasts are being forced to relocate. For villages on small low islands, one terrible storm could wipe out the entire community.

The melting permafrost and increasing temperatures are both affecting the forests of Alaska. As the permafrost under the forests melts, insects that normally do not turn up until the warmer seasons are appearing sooner. The spruce-bark beetle, for example, is increasing in numbers as a result of warmer winter temperatures. It usually takes about two years for these beetles to grow and reproduce in. very cold weather. However, due to the increase in temperatures, spruce-bark beetles are reproducing faster and damaging as many trees in one year as they previously damaged in two. If something cannot be done to change things, Alaska's forests will not survive the turn of the century.

Some scientists believe that human activity is linked to a global increase in weather temperature. Whatever the cause of rising temperatures may be, the fact remains that temperatures are warming, affecting Alaska for the worse. Horribly, this could be a preview of what will happen to the rest of the world in the next century.

Which of the following could be the main topic of the passage?

A. Alaska’s glaciers are reducing. 

B. The reasons Why Alaska is disappearing. 

C. The areas of Alaska’s glaciers are thawing. 

D. The problems Alaska is facing.

Dịch nghĩa:

“Đọc đoạn văn sau và đánh dấu chữ cái A, B, C hoặc D để chỉ ra câu trả lời đúng cho mỗi câu hỏi.

 Alaska đang dần biến mất nhưng chắc chắn. Người ta ước tính rằng kể từ năm 19505, có tới 15% diện tích đất của Alaska đã biến mất. Làm sao cả một bang có thể biến mất được? Vấn đề là sông băng ở Alaska đang tan chảy. Bang này có hơn 100.000 sông băng. Những sông băng này chiếm khoảng 75.000 km2, tương đương 5% diện tích bang. Đó là diện tích đất rộng hơn Ireland!

Theo một báo cáo gần đây của Cơ quan Khảo sát Địa chất Hoa Kỳ, 99% sông băng ở Alaska đang rút lui hoặc giảm dần. Sự giảm dần này dường như chủ yếu là do sự gia tăng nhiệt độ toàn cầu. Kể từ năm 19605, nhiệt độ trung bình quanh năm đã tăng gần 3°C. Ngoài ra, nhiệt độ trung bình mùa đông đã tăng hơn 6°C. Hiện tại, ước tính khoảng 100 km khối băng đang biến mất khỏi các sông băng ở Alaska mỗi năm. Con số này có thể còn cao hơn nữa trong tương lai gần, vì một số nhà khoa học dự đoán rằng nhiệt độ trung bình trên thế giới có thể tăng từ 4 đến 7°C vào năm 2100.

Một vấn đề khác mà Alaska phải đối mặt là lớp băng vĩnh cửu đang tan dần. Phần lớn đất đai ở Alaska từng bị đóng băng hoặc đóng băng vĩnh viễn trong hầu hết thời gian trong năm. Giờ đây, lớp băng vĩnh cửu tan đang gây ra một số vấn đề cho người dân sống ở Alaska. Những con đường và cột điện đang sụp đổ khi mặt đất xung quanh và bên dưới chúng ấm lên và mềm đi. Ngoài ra, lớp băng vĩnh cửu cứng ban đầu ngăn chặn các bãi biển bị xói mòn trong những cơn bão dữ dội hiện đang tan chảy. Những người sống dọc bờ biển Alaska đang bị buộc phải di dời. Đối với những ngôi làng trên những hòn đảo nhỏ thấp, một cơn bão khủng khiếp có thể quét sạch toàn bộ cộng đồng.

Lớp băng vĩnh cửu tan chảy và nhiệt độ ngày càng tăng đều ảnh hưởng đến các khu rừng ở Alaska. Khi lớp băng vĩnh cửu dưới khu rừng tan chảy, những loài côn trùng thường không xuất hiện cho đến mùa ấm hơn sẽ xuất hiện sớm hơn. Ví dụ, loài bọ vỏ cây vân sam đang gia tăng số lượng do nhiệt độ mùa đông ấm hơn. Thông thường phải mất khoảng hai năm để những con bọ này phát triển và sinh sản trong thời tiết rất lạnh. Tuy nhiên, do nhiệt độ tăng lên, bọ vỏ cây vân sam sinh sản nhanh hơn và làm hư hại nhiều cây trong một năm so với trước đây chúng đã phá hủy hai cây. Nếu có điều gì đó không thể làm được thay đổi mọi thứ, rừng Alaska sẽ không tồn tại được khi bước sang thế kỷ mới.

Một số nhà khoa học tin rằng hoạt động của con người có liên quan đến sự gia tăng nhiệt độ thời tiết toàn cầu. Dù nguyên nhân khiến nhiệt độ tăng cao là gì thì thực tế vẫn là nhiệt độ đang ấm lên, khiến Alaska trở nên tồi tệ hơn. Thật khủng khiếp, đây có thể là bản xem trước về những gì sẽ xảy ra với phần còn lại của thế giới trong thế kỷ tới.

Điều nào sau đây có thể là chủ đề chính của đoạn văn?

A. Sông băng ở Alaska đang giảm dần.

B. Những lý do tại sao Alaska đang biến mất.

C. Các khu vực sông băng ở Alaska đang tan băng.

D. Những vấn đề Alaska đang phải đối mặt.
