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

When these early migrants arrived in North America, they found woods and plains dominated by three types of American mammoths. Those 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 human followers. The wooly 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 the time, although they were hunters, humans were still widely scattered and not very numerous. It is difficult to see how they could have prevailed over the mammoth to such an extent.

Câu 46: Where were the imperial mammoths the dominant type of mammoth?

A. the central portion of North America B. Alaska

C. the southern part of North America D. South America

Câu 47: It can be inferred that when humans crossed into the New World, they ______

A. had previously hunted mammoths in Siberia. B. soon learned to use dogs to hun mammoths.

C. brought mammoths with them from the Old World. D. had never seen mammoths before.

A. Humans hunted them to extinction.

B. The cause of their extinction is not definitely known.

C. Competition with mastodons caused them to become extinct.

D. The freezing temperatures of the Ice Age destroyed their food supply.

Câu 49: Which of the following is NOT true about prehistoric humans at the time of the mammoths' extinction?

A. They were relatively few in number. B. They were skilled hunters.

C. They knew how to use bows and arrows. D. They were concentrated in a small area.

Câu 50: Which of the following types of the elephants does the author discuss in the most detail in the passage?
