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

The time when human crossed the Arctic land bridge from Siberia to Alaska seems remote to us today, but actually represents a late stage in the prehistory of humans, an era when polished stone implements and bows and arrows were already being used and dogs had already been domesticated.

When these early migrants arrived in North America, they found the woods and plains dominated by three types of American mammoths. These elephants were distinguished from today’s elephants mainly by their thick, shaggy coats and their huge, upward–curving tusks. They had arrived on the continent hundreds of thousands of years before their followers. The woolly mammoth in the North, the Columbian mammoth in middle North America, and the imperial mammoth of the South, together with their distant cousins the mastodons, dominated the land. Here, as in the Old World, there is evidence that humans hunted these elephants, as shown by numerous spear points found with mammoth remains.

Then, at the end of the Ice Age, when the last glaciers had retreated, there was a relatively sudden and widespread extinction of elephants. In the New World, both mammoths and mastodons disappeared. In the Old World, only Indian and African elephants survived.

Why did the huge, seemingly successful mammoths disappear? Were humans connected with their extinction? Perhaps, but at that time, although they were cunning hunters, humans were still widely settled and not very numerous. It is difficult to see how they could have prevailed over the mammoth to such an extent.

Where were the imperial mammoths the dominant type of mammoth?

A. in South America 

B. in the central portion of North America 

C. in the southern part of North America 

D. in Alaska

Tạm dịch: Khi những người di cư sớm này đến Bắc Mỹ, họ đã tìm thấy những khu rừng và đồng bằng bị thống trị bởi ba loại voi ma mút Mỹ. Những con voi này được phân biệt với voi ngày nay chủ yếu bởi bộ lông dày, xù xì và những chiếc ngà to, cong của chúng.

Dịch bài đọc:

Thời đại khi con người đi qua cây cầu trên đất Bắc Cực từ Siberia đến Alaska có vẻ xa vời đối với chúng ta ngày nay, nhưng nó thực sự là giai đoạn cuối của thời tiền sử của con người, thời đại mà những công cụ mài bằng đá và cung tên được sử dụng và chó đã được thuần hóa.

Khi những người di cư sớm này đến Bắc Mỹ, họ đã tìm thấy những khu rừng và đồng bằng bị thống trị bởi ba loại voi ma mút Mỹ. Những con voi này được phân biệt với voi ngày nay chủ yếu bởi bộ lông dày, xù xì và những chiếc ngà to, cong của chúng. Chúng đã đến lục địa này hàng trăm ngàn năm trước những người đến sau chúng. Loài voi ma mút lông dài ở miền Bắc, voi ma mút Columbia ở miền trung Bắc Mỹ và voi ma mút hoàng gia ở miền Nam, cùng với anh em họ xa của chúng là những con voi răng mấu, thống trị vùng đất. Ở đây, như ở Thế giới cũ, có bằng chứng cho thấy con người đã săn bắt những con voi này, như thể hiện qua nhiều dấu vết của giáo được tìm thấy cùng với hóa thạch của voi ma mút.

Sau đó, vào cuối kỷ băng hà, khi những dòng sông băng cuối cùng đã tan chảy, loài voi đã trải qua một sự tuyệt chủng tương đối bất ngờ và lan rộng. Ở Thế giới mới, cả voi ma mút và voi răng mấu đều biến mất. Ở Thế giới cũ, chỉ có voi Ấn Độ và châu Phi sống sót.

Tại sao những con voi ma mút khổng lồ, dường như thành công biến mất? Có phải con người liên quan đến sự tuyệt chủng của chúng? Có thể, nhưng vào thời điểm đó, mặc dù là những thợ săn xảo quyệt, con người vẫn định cư rải rác và không đông lắm. Thật khó để thấy làm thế nào họ có thể chiếm ưu thế hơn voi ma mút đến mức như vậy.
