Question

[Lê Quỳnh Anh]

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.

          Dinosaurs were reptiles that lived during a period of earth’s history called the Mesozoic Era, which is known as the Age of Reptiles. The first dinosaurs appeared more than 200 million years ago. For many millions of years, they dominated the land with their huge size and strength. Then about 65 million years ago, they died out rather suddenly, never to reemerge.
          The word dinosaur comes from two Greek words meaning “terrible lizard”. Dinosaurs were not lizards, but their appearance could be truly terrifying. The biggest ones weighed more than ten times as much as a mature elephant and nearly equaled the size of most modern—day whales. The famous kinds of dinosaurs, including the brontosaur and tyrannosaurus, reached 80 to 90 feet in length. Not all dinosaurs were giants, however, some were actually no larger than a chicken.
          Scientists still do not know what caused dinosaur to disappear. One theory involves a change in the earth’s climate. It is believed that temperature dropped significantly towards the end of the Cretaceous Period. Too large to hibernate and not having fur or feathers for protection, it is possible that the climate became too chilly for dinosaurs. In contrast, other species having protection, such as the mammals and birds, were able to survive

Which of the following can be inferred about mammals and birds?

A. Most have either fur or feathers over their bodies.

B. They preceded the dinosaurs.

C. They were too large to hibernate.

D. They could not survive the chilly temperatures

Đáp án A

Điều nào có thể suy ra về động vật có vú và chim?
A. Chúng phần lớn có da và lông trên cơ thể.
B. Chúng tồn tại trước khủng long.
C. Chúng quá lớn để ngủ đông.
D. Chúng không thể sống sót qua thời tiết lạnh.
Nói về sự tuyệt chủng của khủng long, giả thuyết đưa đưa ra: “Too large to hibernate and not having fur or feathers for protection, it is possible that the climate became too chilly for dinosaurs. In contrast, other species having protection, such as the mammals and birds, were able to survive.”
(Khủng long quá khổng lồ để ngủ đông, không có da lông bảo vệ, có khả năng khí hậu quá lạnh đối với chúng. Ngược lại, các loài khác có lớp bảo vệ, như động vật có vú hay chim, thì có thể sống sót)
Từ đó ta thấy ĐV có vú và chim có lớp da lông bảo vệ
