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 pollutnt 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 subtances 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 notrigen 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 as 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 subtance to be a pollutant; in fact, the numerial value tells us little until we know how much of an increase this represents over ther 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.

Read the following passage and choose the best answer (A, B, C, D):
The custom of paying a bride price before marriage is still a well-established part of many African cultures. In paying a bride price, the family of the groom must provide payment to the family of the bride before the marriage is allowed. The bride price can vary greatly from culture to culture in Africa. In the Zulu and Swazi tribes of southern Africa, the bride price often takes the form of cattle. In Western African, kola nuts, shells, and other goods are often used for the payment of the bride price. The actual payment of money sometimes takes place, but the payment of goods is more frequent. The amount of paid in a bride price can also vary. In modern times, the bride price is occasionally quite small and its value is mainly symbolic. However, the bride price can still be quite high, especially among prominent or highly traditional families.There are a number of justifications used to explain the payment of bride price. The first is that the bride price represents an acknowledgement of the expense the bride's family has gone in order to raise her and bring her up as a suitable bride for the groom. It also represents payment for the loss of a family member, since the bride will officially become a member of her husband's family and will leave her own. On a deeper level the bride price represents payment for the fact that the bride will bring children into the family of the groom, thereby increasing the wealth of the family. This concept is reinforced by the fact that the bride price must often be returned if the bride fails to bear children.The payment of the bride price has quite a number of effects on African society. First, the payment of bride price acts to increase the stability of African family structures. Sons are dependent on their fathers and older relatives to help them pay the bride price of their wives, and this generally leads to greater levels of obedience and respect. The negotiations between the two families concerning the bride price allow the parents and other family members to meet and get to know one another before the marriage. Finally, since the bride price must often be repaid in case of divorce, the bride's family often works to make sure that any marital problems are solved quickly. Bride prices also work as a system of wealth distribution in African cultures. Wealthier families can afford to support the marriage of their son, and thus their wealth is transferred to other families.Not all of the effects of bride price are so positive, however. One major disadvantage to the system of bride price is that women are often married to men much older than themselves. In many African cultures, the typical age for marriage amongst women is still quite young, lower than in many cases. Yet few men at this age would have the ability to raise the bride price to marry. Thus there is sometimes a significant age gap between husbands and wives. This cuts short the education of many young women. In addition, the husband, being far older, may die whilst the wife is still relatively young, leaving her with the burden of raising the children alone.

Read the following passage and choose the best answer (A, B, C, D):
Genetics is the study of hereditary characteristics that are passed down from one generation of living organisms to another. Although farmers have used selective breeding to improve the resilience of crops and animals, it wasn't until the mid-1800s that Gregor Mendel started the science of genetics as we know it today. Following Mendel's methods, scientists have discovered "chromosomes" and "DNA". With the ability to study DNA, scientists were able to study the genetic differences between races. Modern genetics discovered that all humans are descendants of "Mitochondrial Eve," a woman who lived over 150,000 generations have passed, and many subtle differences are now evident. Humans share at least 99% of their genetic makeup. A 1% difference may not seem like much, but when you consider that a chimpanzee shares 98% of human genes, you realize how much a 1% difference makes! Africans are more closely related to Europeans than any other two groups despite the fact that they differ so much in appearance. The biggest genetic differences are found between Africans and the native populations of Nord America (22%). However, it is essential to note that the genetic differences between people of the same race are much greater than the differences between people of different races. This means that the argument which claims that genets differences make one race superior to another is nothing but a tall story. The differences in various populations may also be the result of circumstances rather than genetic makeup. Factors such as climate, diet, health care, education, and employment as well as other socioeconomic factors are all influential. However, there are some traits which are genetic, for example, then is a much higher incidence of sickle cell anemia among black populations that any other population group. Adult African-Americans and Latinos have twice as many cases of diabetes than Caucasians. In the U.S, Latinos suffer more deaths from liver disease than other races. Europeans suffer more from heart disease and cancer. Genes not only affect our susceptibility to disease, they also affect our physical attributes. The Dinka people from the Sudan are considered to be the tallest people with men having an average height of 6ft 3 in, while women hit the big time with an impressive 5ft 3 in. This contrasts sharply with the Pygmy tribes who get the short end of the stick at only about 4ft 11 in tall. Genetic differences may help US to tailor health service to people of different races or to detect life threatening diseases early. However, they are not significant enough to support the claim that one race is superior to another. In fact, our modern scientific understanding of human genetic diversity flit in the face of almost all our social stereotypes.

A Picture Is Worth a Thousand Words
In 1826, a man named Joseph Nicephore Niepce went to the upstairs window of his home in France. He used a new invention called a camera to take the world’s first photograph of nature. Niepce’s photograph shows us the view from his window. However, it is very difficult to know that when you look at the picture. The image is not very clear at all. That doesn’t matter. On that day, Niepce changed the world forever. Photography first became very popular in the 1850s and 1860s. People liked it because it showed more details than other kinds of art. A painting or a statue might be more beautiful than a photograph, but a photograph can tell you a much clearer story. Many people believe that colour photographs didn’t exist until the 1920s, but that’s not true. The first colour photograph was taken in 1855. It shows a colourful ribbon. Before the 1920s, people didn’t often use colour photography because it was very complicated and expensive. Even after colour photography became easier and cheaper, many people still preferred black and white pictures. They felt that black and white had a more “classic photo” feeling. In the 1940s, colour photography finally replaced black and white. When we think of the history of photography, it is amazing to think of how easy it is to take pictures today. Many years ago, only professionals had cameras. These days, just about everybody has one. One of the biggest reasons for this change is the popularity of smartphones. Almost every modern smartphones. Almost every modern smartphone has a camera. These smartphone cameras are very easy to use and they also take very clear pictures. Most of them have a video function.  One thing that hasn’t changed is the importance of photography. These days, a picture can still create all kinds of feelings and emotions inside of us. There is a saying. “A picture is worth a thousand words.”
