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.

​A. It minimizes risks for economic, cultural and societal development.
​B. It makes water supply system both efficient and effective.  
​C. Weather and climate in the city will be much improved.
​D. People may come up with new ideas for innovation.
Question 38:Which statement is TRUE, according to the passage?
​A. Urbanization brings important benefits for development as well.
​B. 54% of the world's population will live in cities by 2050.
​C. Risks cannot be addressed effectively no matter how well cities are governed.
​D. Rapidly increasing population density can help solve poverty.
Question 39: The word "addressed" in paragraph 2 is closest in meaning to _________.
​A. aimed at ​B. dealt with ​C. added to ​D. agreed on

SECTION III: READING (5.0 points)
Part 1: Read the following passage and choose the correct answer to each of the following
questions. Write your answer (A, B, C, or D) in the numbered boxes.
Since ancient times, one of the most common materials people have utilized to make things
with is wood. Wood is used to make houses, buildings, and other structures. People also
make a large number of smaller objects with it.
The desire to make finished products more beautiful appears to be ingrained in huma n
nature. On account of this fact, for thousands of years, people have carved and shaped
wooden objects to make them more appealing to the eye. Humans have additionally tended
to create both religious and ceremonial objects from wood. In fact, all around the world,
countless cultures have made use of ceremonial wood carvings. These objects often reflect
the spirit of the people who made them, and each of them tends to hold a special
significance as well.
One of the most common types of wood carvings is the mask. People in many cultures in
Asia, Africa, and North America have made ceremonial wooden masks. In Africa, for
instance, large numbers of tribes use wooden masks for vari ous spiritual rituals. These
masks are often in the form of animals that are sacred to the tribes. In other cases, the masks
have human forms. The faces, however, may not be exactly humanlike. For instance, the
faces can be distorted, having wider, longer, smaller, or larger features than normal. The
masks may be carved to give them ugly or frightening appearances as well. And, on other
occasions, the masks are made to look as beautiful as possible.
While masks tend to be fairly small, other wood carvings can be enormous. Among the
largest of all ceremonial wood carvings is the totem p ole. Totem poles have been built by
several Native American tribes that reside in the northwestern part of North America. They
are normally made to represent families, or they may honor significant historical events.
Some even tell stories. A typical totem pole has several individual carvings on it. Each
carving represents a different part of the family history, event, or story. Most totem poles
have human or animal faces, as well as other figures, carved in them. They are so large that
they are made from e ntire trees. Once the trees are cut down, master craftsmen work on
them. When completed, they may or may not be painted. Then, the totem poles are
positioned in places of honor and placed upright.

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.

Earth is richly supplied with different types of living organisms which co-exist in their environments, forming complex, interrelated communities. Living organisms depend on one another for nutrients, shelter, and other benefits. The extinction of one species can set off a chain reaction that affects many other species, particularly if the loss occurs near the bottom of the food chain. For example, the extinction of a particular insect or plant might seem inconsequential. However, there may be fish or small animals that depend on that resource for foodstuffs. The loss can threaten the survival of these creatures and larger predators that prey upon them. Extinction can have a ripple effect that spreads throughout nature.

In addition to its biological consequences, extinction poses a moral dilemma for humans, the only species capable of saving the others. The presence of humans on the planet has affected all other life forms, particularly plants and animals. Human lifestyles have proven to be incompatible with the survival of some other species. Purposeful efforts have been made to eliminate animals that prey on people, livestock, crops, or pose any threat to human livelihoods. Some wild animals have been decimated by human desire for meat, hides, fur, or other body parts with commercial value. Likewise, demand for land, water, and other natural resources has left many wild plants and animals with little to no suitable habitat. Humans have also affected nature by introducing non-native species to local areas and producing pollutants having a negative impact on the environment. The combination of these human-related effects and natural obstacles such as disease or low birthrates has proven to be too much for some species to overcome. They have no chance of survival without human help.

As a result, societies have difficult choices to make about the amount of effort and money they are willing to spend to save imperiled species. Will people accept limits on their property rights, recreational activities, and means of livelihood to save a plant or an animal? Should saving such popular species as whales and dolphins take priority over saving obscure, annoying, or fearful species? Is it the responsibility of humans to save every kind of life form from disappearing, or is extinction an inevitable part of nature, in which the strong survive and the weak perish? These are some difficult questions that people face as they ponder the fate of other species living on this planet.

What does the passage mainly discuss?

A. Humans and endangered species

B. The importance of living organisms

C. Measures to protect endangered species

D. Causes of animal extinction

We live in a dynamic world, and habitats are always undergoing changes at all sorts of levels. However, natural changes usually occur at a slow pace so that impacts on individual species tend to be slight - at least in the short term
When the pace of change is greatly accelerated, there may be no time for individual species to react to new circumstances, and the effects can be disastrous. Briefly, this is the reason that rapid habitat loss is regarded as the chief cause of species endangerment, and there is no force more powerful in this regard than human beings. To some extent, every part of the earth has been affected by human activities, especially during this past century. This applies on virtually every scale, from the loss of microbes in soils that once supported tropical forests, to the extinction of fish and other aquatic species in polluted freshwater habitats, to changes in global climate caused by the release of greenhouse gases. From the perspective of an individual human lifetime, such changes may be hard to detect and their effects on individual species may be hard to predict. But the lesson is clear enough. For example, although many countries have had plans to grow many tropical forests, they are highly susceptible to destruction because the soils in which they grow are poor in available nutrients. Centuries may be required to bring back a forest that was cut down or burnt out in the space of a few years. Many of the world's severely threatened animals and plants live in such forests, and it is certain that huge numbers of them will disappear if present rates of forest loss continue. Habitats in the world are unchangeable and fixedly exist.

Chúng ta sống trong một thế giới năng động, và môi trường sống luôn luôn trải qua những thay đổi ở tất cả các cấp độ. Tuy nhiên, những thay đổi tự nhiên thường xảy ra ở tốc độ chậm để tác động đến từng loài có xu hướng nhỏ - ít nhất là trong ngắn hạn
Khi tốc độ thay đổi được tăng tốc đáng kể, có thể không có thời gian để các loài cá thể phản ứng với hoàn cảnh mới, và các hiệu ứng có thể là thảm họa. Tóm lại, đây là lý do khiến mất môi trường sống nhanh chóng được coi là nguyên nhân chính gây nguy hiểm cho loài, và không có lực lượng nào mạnh hơn trong vấn đề này so với con người. Ở một mức độ nào đó, mọi phần của trái đất đã bị ảnh hưởng bởi các hoạt động của con người, đặc biệt là trong thế kỷ qua. Điều này áp dụng trên hầu hết mọi quy mô, từ việc mất vi khuẩn trong đất đã từng hỗ trợ rừng nhiệt đới, đến sự tuyệt chủng của cá và các loài thủy sinh khác trong môi trường nước ngọt bị ô nhiễm, thay đổi khí hậu toàn cầu gây ra bởi việc thải khí nhà kính. Từ quan điểm của một đời người, những thay đổi như vậy có thể khó phát hiện và ảnh hưởng của chúng đối với từng loài có thể khó dự đoán. Nhưng bài học là đủ rõ ràng. Ví dụ, mặc dù nhiều quốc gia đã có kế hoạch trồng nhiều khu rừng nhiệt đới, chúng rất dễ bị phá hủy bởi vì các loại đất mà chúng phát triển rất nghèo trong các chất dinh dưỡng sẵn có. Nhiều thế kỷ có thể được yêu cầu mang lại một khu rừng bị cắt giảm hoặc bị đốt cháy trong không gian vài năm. Nhiều loài động vật và thực vật bị đe dọa nghiêm trọng trên thế giới sống trong các khu rừng như vậy, và chắc chắn rằng một số lượng lớn chúng sẽ biến mất nếu tỷ lệ mất rừng hiện tại tiếp tục. Môi trường sống trên thế giới là không thể thay đổi và tồn tại cố định.
