Read the following passage and choose the correct answer A, B, C or D. 
 In many ways, the increasingly rapid pace of climate change is a direct result of the growth of the human population. In the last 100 years, the world population has more than tripled. Obviously, this has meant that the world has needed to produce three times as much food, energy, and other natural resources.
 In addition, the average person uses more energy and natural resources than the average person one hundred years ago, meaning that the rates of consumption are actually much higher than just the increase in population would imply. 
All of these activities: food production, energy usage, and the use of natural resources, contribute to climate change in some way. The greater amounts of oil and other fuels burned to create energy release chemicals which add to global warming. In order to produce more food, farmers cut down trees to gain more land for their fields. In addition, we cut down trees to build the houses needed for a larger population. Those trees are an essential part of controlling global warming.
 In addition to a growing population, the world also has a population that desires a higher standard of living than in the past, and a higher standard of living requires the use of even more natural resources. For example, China is the world’s most populous nation, with 1.3 billion people. Currently, the standard of living for most of those people is far below that of people in first world nations. Therefore, the average Chinese citizen uses far fewer natural resources and less energy than the average citizen of the US or Japan. If every Chinese person attains a first world lifestyle, the amount of energy and natural resources needed in the world will double, even if the standard of living in every other nation on Earth remains the same as it is today.
1. The word “pace” in the passage is closest in meaning to _____.
A. growth	B. speed	C. problem	D. pollution
2. The word “consumption” in the passage is closest in meaning to _____.
A. development	B. usage	C. population	D. increase
3. According to the passage, how does food production contribute to global warming?
A. Food production requires that the forests be cleared to create farmland.
B. Food production uses many chemicals which add to global warming.
C. Producing more food leads to growth in the world population.
D. Food production decreases the ability of the air to release heat.
4. According to the passage, how does the standard of living affect global warming?
A. Higher standards of living are better for the environment.
B. First world nations create less population than developing nations.
C. The use of natural resources is directly related to the standard of living.
D. High standards of living lead to increases in world population.
5. Why does the author discuss China, Japan and the United States?
A. To compare the standards of their citizens.
B. To explain why China will not be able to become a first world nation.
C. To explain why the world’s use of energy will need to double soon.
D. To better illustrate the effects of an increase in standards of living.

 As computers have become powerful tools for the rapid and economic production of pictures, computer graphics has emerged as one of the most rapidly growing fields in computer science. It is used routinely in such diverse areas as business, industry, art, government, education, research, training, and medicine.
 One of the initial uses of computer graphics, and ultimately its greatest use, has been as an aid to design, generally to referred to as computer-aided design (CAD). One of its greatest advantages is that designers can see how an object will look after construction and make changes freely and much more quickly than with hand drafting. For three-dimensional rendering of machine parts, engineers now rely heavily on CAD. Automobile, spacecraft, aerospace, and ship designers use CAD techniques to design vehicles and test their performance. Building designs are also created with computer graphics system. Architects can design a building layout, create a three-dimensional model, and even go for a simulated ‘walk’ through the rooms or around the outside of the building.
 Business graphics is another rapidly growing area of computer graphics, where it is used to create graphs, charts, and cost models to summarize financial, statistical, mathematical, scientific, and economic data. As an educational aid, computer graphics can be used to create weather maps and cartographic materials. Computer art also has creative and commercial art applications, where it is used in advertising, publishing, and film productions, particularly for computer animation, which is achieved by a sequential process.
