The Power of Crowdsourcing
There is a famous old saying that when trying to solve a problem “two heads are better than one”. Yet until recently, businesses would often rely on one key person to get important tasks done. But thanks to a phenomenon called crowdsourcing, more and more companies are allowing their consumers to have their say when designing new products. The term “crowdsourcing” refers to the process of outsourcing jobs which were once done by a single person to a large group (or a crowd) of people. In the past, crowdsourcing wasn’t practical, as it was impossible to gather thousands of like-minded people together to share opinions. Now, thanks to the Internet, online forums, and social media, this isn’t a difficult task at all. There are many important applications for crowdsourcing in business. For example, if a small business was looking to develop a business logo, it might employ a single designer and hope for the best. However, with crowdsourcing, companies can specify some guidelines about their project, set a budget, and start a design contest online. Within hours, it will likely receive hundreds of designers sending them logos. In the end, they can choose the design they like best and the winner will get compensated. Crowdsourcing has other applications as well. A website called Duolingo is using crowdsourcing to translate documents into different languages. It offers free lessons to language learners. As part of their tests, users translate lines to test their knowledge. Then, a computer programme will analyze thousands of test results for consistency and arrange an accurate translation. Not everyone is sold on crowdsourcing, though. In many cases, it may be better to rely on the opinion of a few specialized professionals than information from a crowd. For instance, it makes more sense to trust the opinion of one top doctor than to take the advice of 1,000 random people regarding a health issue. Another criticism is the low wage that crowdworkers usually receive. Since crowdworkers are freelancers and not employees, they can be paid less than minimum wage. Whether you love or hate crowdsourcing, it appears to be here to stay. So before you make any financial judgements, consider following the crowd and give crowdsourcing a try.
4. According to the passage, why didn’t businesses use crowdsourcing in the past?

Alemur is a unique animal. When you look at a lemur, it might be hard to tell what you are really looking at. With their huge dark eyes and lush fur, lemurs are very cute, but what animal family are they from? Some lemurs look like a cross between a cat and a dog. Some look a little like squirrels, while others resemble monkeys. Why do they look so strange? To answer to this question we need to understand the lemur's history and genetics. In modern biology, lemurs are called prosimians. This means before monkeys. Remarkably, lemurs, monkeys, apes, and humans all share a common ancestor from about 50 million years ago. Monkeys, apes, and humans developed together in one direction. However, lemurs developed differently and slowly because of their geographical location. All lemurs come from the island of Madagascar, located off the east coast of Africa. Madagascar split off from mainland Africa 50 million years ago. It is believed that the first prosimians traveled to Madagascar on floating trees and plants. The prosimians that traveled to Madagascar were isolated from the rest of Africa. Predators, like dogs or cats, did not make it to Madagascar. Since there were no dangerous threats, prosimians did not have to evolve as quickly as other primates did. (primates: any nimal that belongs to the group of mammals that includes humans, apes, and monkeys.) Over time, the original prosimians evolved into lemurs. Lemurs have changed in some ways over those 50 million years, but they are much more similar to our shared ancestor than either humans, monkeys, or apes. Because of this, their bodies and behaviors hold clues about what out common ancestor looked like. Lemurs have four fingers and a thumb on their hands, and five toes on their feet, just like humans do. They have eyes and jaw bones that are similar to humans as well, but they have a wet nose, like a dog. Lemur behavior is also comparable to human behavior, as they live in social groups. Like apes and humans, lemurs travel together, groom one another, fight each other, and play together. Lemurs, however, have simpler friend and family relationships. Recently, lemurs have been studied in captivity. Like their distant chimpanzee and monkey cousins, they can be taught to use tools and to solve complicated problems. The word lemur means ghost. While the name probably comes from their huge reflective eyes and their strange, haunting cries, lemurs are ghosts in a way. They are living ghosts that remind US where we came from, and also give US clues about how humans evolved.

The mineral particles found in soil range in size from microscopic clay particles to large boulders. The most abundant particles - sand, silt, and clay - are the focus of examination in studies of soil texture. Texture is the term used to describe the line composite sizes of particles in a soil sample, typically several representative handfuls. To measure soil texture, the sand, silt, and clay particles are sorted out by size and weight. The weights of each size are then expressed as a percentage of the sample weight.
In the field, soil texture can be estimated by extracting a handful of sod and squeezing the damp soil into three basic shapes; cast, a lump formed by squeezing a sample in a clenched fist; thread, a pencil shape formed by rolling soil between the palms; and ribbon, a flatfish shape formed by squeezing a small sample between the thumb and index finger. The behavioral characteristics of the soil when molded into each of these shapes, if they can be formed at all, provides the basis for a general textural classification. The behavior of the soil in the hand test is determined by the amount of clay in the sample. Clay particles are highly cohesive, and when dampened, behave as a plastic. Therefore the higher the clay content in a sample, the more refined and durable the shapes into which it can be molded.
Another method of determining soil texture involves the use of devices called sediment sieves, screens built with a specified mesh size. When the soil is filtered through a group of sieves, each with a different mesh size, the particles become grouped in corresponding size categories. Each category can be weighed to make a textural determination. Although sieves work well for silt, sand, and larger particles, they are not appropriate for clay particles. Clay is far too small to sieve accurately; therefore, in soils with a high proportion of clay, the fine particles are measured on the basis of their settling velocity when suspended in water. Since clays settle so slowly, they
are easily segregated from sand and silt. The water can be drawn off and evaporated, leaving a residue of clay, which can be weighed.

It can be inferred from the passage that the sediment sieve has an advantage over the hand test in determining soil texture because         .

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.

Early peoples had no need of engineering works to supply their water. Hunters and nomads camped near natural sources of fresh water, and populations were so sparse that pollution of the water supply was not a serious problem. After community life developed and agricultural villages became urban centres, the problem of supplying water became important for inhabitants of a city, as well as for irrigation of the farms surrounding the city. Irrigation works were known in prehistoric times, and before 2000 BC the rulers of Babylonia and Egypt constructed systems of dams and canals to impound the flood waters of the Euphrates and Nile rivers, controlling floods and providing irrigation water throughout the dry season. Such irrigation canals also supplied water for domestic purposes. The first people to consider the sanitation of their water supply were the ancient Romans, who constructed a vast system of aqueducts to bring the clean waters of the Apennine Mountains into the city and built basins and filters along these mains to ensure the
clarity of the water. The construction of such extensive water-supply systems declined when the Roman Empire disintegrated, and for several centuries local springs and wells formed the main source of domestic and industrial water. The invention of the force pump in England in the middle of the 16th century greatly extended the possibilities of development of water-supply systems. In London, the first pumping waterworks was completed in 1562; it pumped river water to a reservoir about 37 m above the level of the River Thames and from the reservoir the water was distributed by gravity, through lead pipes, to buildings in the vicinity. Increased per-capita demand has coincided with water shortages in many countries. Southeast England, for example, receives only 14 per cent of Britain's rainfall, has 30 per cent of its population, and has experienced declining winter rainfall since the 1980s.
In recent years a great deal of interest has been shown in the conversion of seawater to fresh water to provide drinking water for very dry areas, such as the Middle East. Several different processes, including distillation, electrodialysis, reverse osmosis, and direct-freeze evaporation, have been developed for this purpose. Some of these processes have been used in large facilities in the United States. Although these processes are successful, the cost of treating seawater is much higher than that for treating fresh water.

Which of the following is NOT mentioned as a process of conversing seawater to freshwater?

Carbohydrates, which are sugars, are an essential part of a healthy diet. They provide the main source of energy for the body, and they also function to flavor and sweeten foods. Carbohydrates range from simple sugars like glucose to complex sugars such as amylose and amylopectin. Nutritionists estimate that carbohydrates should make up about one-fourth to one-fifth of a person's diet. This translates to about 75- 100 grams of carbohydrates per day. A diet that is deficient in carbohydrates can have an adverse effect on a person's health. When the body lacks a sufficient amount of carbohydrates it must then use its protein supplies for energy, a process called gluconeogenesis. This, however, results in a lack of necessary protein, and further health difficulties may occur. A lack of carbohydrates can also lead to ketosis, a buildup of ketones in the body that causes fatigue, lethargy, and bad breath.

Although only a small percentage of the electromagnetic radiation that is emitted by the Sun is ultraviolet (UV) radiation, the amount that is emitted would be enough to cause severe damage to most forms of life on Earth were it all to reach the surface of the Earth. Fortunately, all of the Sun’s ultraviolet radiation does not reach the Earth because of a layer of oxygen, called the ozone layer encircling the Earth in the stratosphere at an altitude of about 15 miles above the Earth. The ozone layer absorbs much of the Sun’s ultraviolet radiation and prevents it from reaching the Earth. Ozone is a form of oxygen in which each molecule consists of three atoms (O3) instead of the two atoms (O2) usually found in an oxygen molecule. Ozone forms in the stratosphere in a process that is initiated by ultraviolet radiation from the Sun. UV radiation from the Sun splits oxygen molecules with two atoms into free oxygen atoms, and each of these unattached oxygen atoms then joins up with an oxygen molecule to form ozone. UV radiation is also capable of splitting up ozone molecules; thus, ozone is constantly forming, splitting, and reforming in the stratosphere. When UV radiation is absorbed during the process of ozone formation and reformation, it is unable to reach Earth and cause damage there. Recently, however, the ozone layer over parts of the Earth has been diminishing. Chief among the culprits in the case of the disappearing ozone, those that are really responsible, are the chlorofluorocarbons (CFCs). CFCs meander up from Earth into the stratosphere, where they break down and release chlorine. The released chlorine reacts with ozone in the stratosphere to form chlorine monoxide (ClO) and oxygen (O2). The chlorine then becomes free to go through the cycle over and over again. One chlorine atom can, in fact, destroy hundreds of thousands of ozone molecules in this repetitious cycle, and the effects of this destructive process are now becoming evident.
