Read the followingpassage and mark the letter A, B, C or D on your answer sheet to indicate the correct answer for each of the question.

It is estimated that over 99 percent of all species that ever existed have become extinct. What causes extinction? When a species is no longer adapted to a change environment, _it may perish. The exact causes of a species’ death vary from situation to situation. Rapid ecological change may render an environment hostile to a species. For example, temperatures may change and a species may not be adapt. Food resources may be affected by environmental changes, which will then cause problems for a species requiring these resources. Other species may become better adapted to an environment, resulting in competition and, ultimately,    in the death of a species.

The fossil record reveals that extinction has occurred throughout the history of Earth. Recent analyses have also revealed that on some occasions many species became extinct at the same time - a mass extinction. One of the best - known examples of mass extinction occurred 65 million years ago with the demise of dinosaurs and many other forms of life. Perhaps the largest mass extinction was the one that occurred 225 million years ago, when approximately 95 percent of all species died. Mass extinctions can be caused by a relatively rapid change in the environment and can be worsened by the close interrelationship of many species. If, for example, something were to happen to destroy much of the plankton in the oceans, then the oxygen content of Earth would drop, affection even organisms not living in the oceans. Such a change would probably lead to a mass extinction.

One interesting, and controversial, finding is that extinctions during the past 250 million years have tended to be more intense every 26 million years. The periodic extinction might be due to intersection of the earth’s orbit with a cloud of comets, but this theory is purely speculative. Some researchers have also speculated that extinction may often be random. That is, certain species may be eliminated and others may survive for no particular reason. A species’ survival may have nothing to do with its ability or inability to adapt. If so, some of revolutionary history may reflect a sequence of essentially random events.

 

Which of the following is NOT mentioned in paragraph 1 as resulting from rapid ecological change? 

A. Temperature changes 

B. Availability of food resources 

C. Introduction of new species 

D. Competition among species

Scotland: The Land of Legends

If we travel all over Scotland, we can see that it has three main parts: Lowlands, Uplands and Highlands with their Grampian Mountains, where the tallest mountain peak, Ben Nevis, is located.

You are sure to enjoy the beauty of the Scottish varied landscape: the hills covered with purple heather, its beautiful lakes (here they are called lochs), its green and narrow valleys.

The biggest and the most beautiful lake in Scotland is Loch Lomond, but the most famous one is Loch Ness with its mysterious monster Nessie. Nessie sometimes appears to scare the tourist but only in fine weather!

But what can be more curious and attractive for tourist than a man in the kilt, playing the bagpipes? The Celts of Scotland made the chequered pattern of tartan – the national dress of the country. The earliest Scots formed themselves into clans (family groups) and the tartan became a symbol of the sense of kinship. There are about 300 different clans in Scotland, and each has its own colour and pattern of tartan together with the motto.

Scotland is a land of many famous people: writer and poets, scientist and philosophers, such as Robert Burns, Arthur Conan Doyle, Alexander Graham Hell, or Alexander Fleming.
Question: In early times, 300 clans were different from each other in __________.

(2 Points)

. the chequered pattern of tartan and the sense of kinship

. its area and population and beautiful landscape

. its own colour and pattern of tartan together with the motto

. its green and narrow valley where they lived

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 from 36 to 42.
 
It is estimated that by 2050 more than two-thirds of the world's population will live in cities, up from about 54 percent today. While the many benefits of organized and efficient cities are well understood, we need to recognize that this rapid, often unplanned urbanization brings risks of profound social instability, risks to critical infrastructure, potential water crises and the potential for devastating spread of disease. These risks can only be further exacerbated as this unprecedented transition from rural to urban areas continues.
How effectively these risks can be addressed will increasingly be determined by how well cities are governed. The increased concentration of people, physical assets, infrastructure and economic activities mean that the risks materializing at the city level will have far greater potential to disrupt society than ever before.
Urbanization is by no means bad by itself. It brings important benefits for economic, cultural and societal development. Well managed cities are both efficient and effective, enabling economies of scale and network effects while reducing the impact on the climate of transportation. As such, an urban model can make economic activity more environmentally-friendly. Further, the proximity and diversity of people can spark innovation and create employment as exchanging ideas breeds new ideas.
But these utopian concepts are threatened by some of the factors driving rapid urbanization. For example, one of the main factors is rural-urban migration, driven by the prospect of greater employment opportunities and the hope of a better life in cities. But rapidly increasing population density can create severe problems, especially if planning efforts are not sufficient to cope with the influx of new inhabitants. The result may, in extreme cases, be widespread poverty. Estimates suggest that 40% of the world's urban expansion is taking place in slums, exacerbating socio-economic disparities and creating unsanitary conditions that facilitate the spread of disease.
The Global Risks 2015 Report looks at four areas that face particularly daunting challenges in the face of rapid and unplanned urbanization: infrastructure, health, climate change, and social instability. In each of these areas we find new risks that can best be managed or, in some cases, transferred through the mechanism of insurance.
