PASSAGE 15

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.
