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.            An air pollutant is defined as a compound added directly or indirectly by humans to the atmosphere in such quantities as to affect humans, animals, vegetation, or materials adversely. Air pollution requires a very flexible definition that permits continuous change. When the first air pollution laws were established in England in the fourteenth century, air pollutants were limited to compounds that could be seen or smelled - a far cry from the extensive list of harmful substances known today. As technology has developed and knowledge of the health aspects of various chemicals has increased, the list of air pollutants has lengthened. In the future, even water vapor might be considered an air pollutant under certain conditions.          Many of the more important air pollutants, such as sulfur oxides, carbon monoxide, and nitrogen oxides, are found in nature. As the Earth developed, the concentration of these pollutants was altered by various chemical reactions; they became components in biogeochemical cycles. These serve as an air purification scheme by allowing the compounds to move from the air to the water or soil. On a global basis, nature's output of these compounds dwarfs that resulting from human activities.          However, human production usually occurs in a localized area, such as a city. In such a region, human output may be dominant and may temporarily overload the natural purification scheme of the cycles. The result is an increased concentration of noxious chemicals in the air. The concentrations at which the adverse effects appear will be greater than the concentrations that the pollutants would have in the absence of human activities. The actual concentration need not be large for a substance to be a pollutant; in fact, the numerical value tells us little until we know how much of an increase this represents over the concentration that would occur naturally in the area. For example, sulfur dioxide has detectable health effects at 0.08 parts per million (ppm), which is about 400 times its natural level. Carbon monoxide, however, has a natural level of 0.1 ppm and is not usually a pollutant until its level reaches about 15 ppm.For which of the following reasons can natural pollutants play an important role in controlling air pollution?

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.            In most discussions of cultural diversity, attention has focused on visible, explicit aspects of culture, such as language, dress, food, religion, music, and social rituals. Although they are important, these visible expressions of culture, which are taught deliberately and learned consciously, are only the tip of the iceberg of culture. Much of culture is taught and learned implicitly, or outside awareness. Thus, neither cultural insiders nor cultural outsiders are aware that certain “invisible” aspects of their culture exist.           Invisible elements of culture are important to us. For example, how long we can be late before being impolite, what topics we should avoid in a conversation, how we show interest or attention through listening behaviour, what we consider beautiful or ugly- these are all aspects of culture that we learn and use without being aware of it. When we meet other people whose invisible cultural assumptions differ from those we have learned implicitly, we usually do not recognize their behaviour as cultural in origin.            Differences in invisible culture can cause problems in cross-cultural relations. Conflicts may arise when we are unable to recognize others’ behavioural differences as cultural rather than personal. We tend to misinterpret other people’s behaviour, blame them, or judge their intentions or competence without realizing that we are experiencing cultural rather than individual differences.            Formal organizations and institutions, such as schools, hospitals, workplaces, governments, and the legal system are collection sites for invisible cultural differences. If the differences were more visible, we might have less misunderstanding. For example, if we met a man in a courthouse who was wearing exotic clothes, speaking a language other than ours, and carrying food that looked strange, we would not assume that we understood his thoughts and feelings or that he understood ours. Yet when such a man is dressed similarly to us, speaks our language, and does not differ from us in other obvious ways, we may fail to recognize the invisible cultural differences between us. As a result, mutual misunderstanding may arise.Which of the following would most likely result in misunderstanding?

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.         Sunlight is solar energy. Sunlight is needed for growing plants that you eat to get energy. Sunlight is also used to make clean electricity. Burning fossil fuels to make electricity pollutes our atmosphere and rivers. Fossil fuels are expensive and limited sources of energy. Nuclear fission is used to create enormous amount of heat and electricity. However, nuclear fission forms dangerous radioactive waste.           Sunlight offers many ways to get energy. A window can allow warm sunlight into your room. Solar water-heating systems can use sunlight to warm the water for your home, swimming pool and school. Sunlight also warms the Earth and causes wind. Electricity can be made by wind generators. Photovoltaic, or PV system use a type of material that converts sunlight into electricity. PV systems can power your air conditioner or a satellite like the International Space Station. PV systems are also used to run a calculator, recharge cell phone, or even power lightweight cars.           Sunlight is also changed into electricity by concentrating solar power or CSP systems. CSP systems have mirrors that focus the sunlight. The concentrated sunlight turns water into steam which turns a turbine that is connected to an electric generator. A CSP system usually uses sunlight to make steam. CSP power plants can store large amount of heat. The stored heat is used to make electricity at night. During cloud days, many CSP plants can also burn natural gas to provide the heat that is used to turn water into steam.          Sunlight provides the energy needed to grow plants and make large amount of environmentally friendly heat and electricity. Solar energy can provide power today and for a long time in the future.In the fourth paragraph, the word “which” refers to _______
