Read the following passage and choose the best answer (A, B, C, D):
A satellite is best understood as a projectile, or an object that has only one force acting on it — gravity. Technically speaking, anything that crosses the Karman Line at an altitude of 100 kilometers (62 miles) is considered in space. However, a satellite needs to be going fast — at least 8 km (5 miles) a second — to stop from falling back down to Earth immediately. If a satellite is traveling fast enough, it will perpetually “fall” toward Earth, but the Earth’s curvature means that the satellite will fall around our planet instead of crashing back on the surface. Satellites that travel closer to Earth are at risk of falling because the drag of atmospheric molecules will slow the satellites down. Those that orbit farther away from Earth have fewer molecules to contend with. There are several accepted “zones” of orbits around the Earth. One is called lowEarth-orbit, which extends from about 160 to 2,000 km (about 100 to 1,250 miles). This is the zone where the ISS orbits and where the space shuttle used to do its work. In fact, all human missions except for the Apollo flights to the moon took place in this zone. Most satellites also work in this zone. Geostationary or geosynchronous orbit is the best spot for communications satellites to use, however. This is a zone above Earth’s equator at an altitude of 35,786 km (22,236 mi). At this altitude, the rate of “fall” around the Earth is about the same as Earth’s rotation, which allows the satellite to stay above the same spot on Earth almost constantly. The satellite thus keeps a perpetual connection with a fixed antenna on the ground, allowing for reliable communications. When geostationary satellites reach the end of their life, protocol dictates they’re moved out of the way for a new satellite to take their place. That’s because there is only so much room, or so many “slots” in that orbit, to allow the satellites to operate without interference. While some satellites are best used around the equator, others are better suited to more polar orbits — those that circle the Earth from pole to pole so that their coverage zones include the north and south poles. Examples of polar-orbiting satellites include weather satellites and reconnaissance satellites  
6. According to paragraph 4, which of the following is the reason why satellites move out of the way?

A massage is relaxing, and makes you feel great, but did you know that it's also good for you? That's what doctors are now saying. Massage relieves pain and anxiety, eases depression and speeds up recovery from medical problems.
Research has shown that people of all ages benefit from touch. Premature infants who are held develop faster than those left alone, and healthy babies who get a lot of physical contact cry less and sleep better. Researchers are not sure why this occurs but they have also found out that touch can slow heart rate, lower blood pressure and increase levels of seratonin, the brain chemical that is linked to well-being. It also decreases levels of the stress hormone cortisol, and this in turn increases your resistance to illness.
Massage also speeds up healing. Bone-marrow transplant patients who were given massages had better neurological function than those who weren't. Furthermore, massage reduced pain by 37% in patients with chronic muscle aches.
Giving someone a massage may be as good as getting one. A study conducted by the university of Miami found that mothers suffering from depression felt better after massaging their infants. In that same study, elderly volunteers who massaged infants reported feeling less anxious and depressed.
It even works when you do it yourself; 43% of headache sufferers reported getting relief after massaging their temples and neck and smokers who were taught self-massage while trying to quit felt less anxiety and smoked less.

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 following questions:
The United States Department of Education describes “giftedness” as exceptionally advanced performance or the potential for outstanding performance in intellectual, creative leadership, artistic, or specific academic fields. Children who demonstrate outstanding talents come from all social, cultural, and economic groups.
Educators believe that gifted students require special education services because their learning needs differ significantly from those of the general population. They learn more rapidly and are able to understand more abstract and complex ideas. They are also able to transform existing knowledge into new and useful forms, and to create new knowledge recognized for its originality, complexity, and elegance. Special education services and facilities for gifted children may enhance these abilities. In addition, some gifted learners may require special counseling services to address social or emotional adjustment issues that are complicated by their exceptional abilities.
Many regular elementary and secondary schools in the United States offer special programs designed specifically to meet the needs of gifted students. Some schools provide specialized education programs to gifted children exclusively. These schools offer advanced education in mathematics, science, technology, the arts, or other academic disciplines. Many schools rely on intelligence tests to identify gifted students. However, most guidelines for determining giftedness recommend the use of a combination of standardized test scores, rating systems developed by individual schools, classroom observation records, and performance assessments.
Gifted children may study a specially modified curriculum or may progress through academic subjects at an accelerated pace. Acceleration involves adapting education programs so that students may progress through particular subject material quicker than usual. These modifications may take place within the regular classroom setting or they may involve changing the child’s placement in school. Some gifted children gain early entrance to kindergarten, skip grades, enter college earlier than usual, or take specific courses with older children. Ideal programs for gifted students consider the individual needs of children and offer multiple options for services. These programs generally involve both advanced course materials and acceleration.

In the USA, the UK and many other countries, a lot of babies were born in the “baby boom” of the late 1940s and 1950s; after that the birth-rate fell. Baby boomers have now retired, or are approaching retirement, and this is causing headaches for many organizations: there are not enough people to succeed their top managers when they retire.
Does your organization have key staff who can’t easily be replaced? A CEO or financial director, perhaps, or a technical expert with knowledge that nobody else in the organization has. If your answer is “yes”, what will happen when they retire, or leave for another company? Will you wait until the last moment before looking for someone to replace them? Or is your organization thinking about likely future changes now, as it should be, and making plans, so that there is likely to be someone ready to replace the person leaving? If the answer is that you are planning ahead, your organization is carrying out succession planning.
Succession planning means looking inside the organization for “high-fliers” - current staff members with the potential to fill key positions - and planning the training, responsibilities and promotion they need, to make them ready when a senior vacancy occurs - which may not be for several years. The company benefits by being able to make an internal promotion when a key person leaves, and in the meantime it benefits by developing the skills of its high-fliers and encouraging them to stay. And the high-fliers benefit, because they achieve their full potential, a career is planned for them within the organization, and they can look forward to a senior post in time.
The training program planned for the high-fliers will help them to develop the leadership skills they need for more senior roles, skills such as planning long-term strategies. A career path is also planned, so that each high-flier moves into a number of different positions over a few years, to gain the experience and know ledge they need.
Sometimes a staff member is chosen as a potential successor to a particular senior manager, but a better method is for organizations to select a number of high-fliers, and prepare them for a range of senior roles. An organization can’t be certain when a particular senior manager will leave. Having a group of people being prepared fee top positions makes it easier to replace someone who leaves unexpectedly, and also means that there are other people available if a high-flier leaves the company.

Read the following passage and choose the best answer (A, B, C, D):
Because the low latitudes of the Earth, the areas near the equator, receive more heat than the latitudes near the poles, and because the nature of heat is to expand and move, heat is transported from the tropics to the middle and high latitudes. Some of this heat is moved by winds and some by ocean currents, and some gets stored in the atmosphere in the form of latent heat. The term “latent heat” refers to the energy that has to be used to convert liquid water to water vapor. We know that if we warm a pan of water on a stove, it will evaporate, or turn into vapor, faster than if it is allowed to sit at room temperature. We also know that if we hang wet clothes outside in the summertime they will dry faster than in winter, when temperatures are colder. The energy used in both cases to change liquid water to water vapor is supplied by heat – supplied by the stove in the first case and by the Sun in the latter case. This energy is not lost. It is stored in water vapor in the atmosphere as latent heat. Eventually, the water stored as vapor in the atmosphere will condense to liquid again, and the energy will be released to the atmosphere. In the atmosphere, a large portion of the Sun’s incoming energy is used to evaporate water, primarily in the tropical oceans. Scientists have tried to quantify this proportion of the Sun’s energy. By analyzing temperature, water vapor, and wind data around the globe, they have estimated the quantity to be about 90 watts per square meter, or nearly 30 percent of the Sun’s energy. Once this latent heat is stored within the atmosphere, it can be transported, primarily to higher latitudes, by prevailing, large-scale winds. Or it can be transported vertically to higher levels in the atmosphere, where it forms clouds and subsequent storms, which then release the energy back to the atmosphere

At a time when the younger generation, hooked to the mobiles, TV and internet, is fast-moving away from books, Sundargarh Collector Nikhil Pasan Kalyan has taken it upon himself this particular sacred responsibility. Kalyan on Thursday launched a campaign ‘Sundargarh Bahi Padha’ to promote reading by distributing books among the people in Sundargarh town. He reached out to the people at roadside stalls and engaged with them over cups of tea. While motivating them to read, he gifted books to them. The district administration plans to extend the initiative to schools and villages in the coming six months with focus on improving school and public libraries, and equipping all offices and waiting rooms with books. Further, reading sessions have been scheduled to be conducted every week at the Collector’s residence campus and other places involving people of all ages including students. “Books are the best teachers. To improve morality and openness in the society, everyone has to read. They could be in any genre. Reading is the starting point,” said Kalyan. Chief District Medical and Public Health Officer (CDM-PHO) Dr SK Mishra commented on the present situation: “Youths and students confine themselves to prescribed courses of study and refuse to go beyond that,” he said. Undoubtedly, internet connection and electronic gadgets like computers, laptops and mobile phones provide a sea of information and ready-made knowledge but simultaneously decrease the creativity in individuals, Mishra added. “Social media kills time, creativity and the urge to pick up a book. It may be noted that people with reading habits have lesser chances of suffering from Alzheimer’s,” he said. Presently, of the four Government-run public libraries in the district three are functional, albeit with few readers. Kalyan has sought collective participation to make the initiative a success

Esperanto is what is called a planned, or artifiial, language. It was created more than a century ago by Polish eye doctor Ludwik Lazar Zamenhof. Zamenhof believed that a common language would help to alleviate some of the misunderstandings among cultures. In Zamenhof's fist attempt at a universal language, he tried to create a language that was as uncomplicated as possible. This fist language included words such as ab, ac, ba, eb, be, and ce.This did not result in a workable language in that these monosyllabic words, though short, were not easy to understand or to retain. Next, Zamenhof tried a different way of constructing a simplified language. He made the words in his language sound like words that people already knew, but he simplifid the grammar tremendously. One example of how he simplifid the language can be seen in the suffies: all nouns in this language end in o, as in the noun amiko, which means "friend", and all adjectives end in -a, as in the adjective bela, which means "pretty". Another example of the simplifid language can be seen in the prefi mal-, which makes a word opposite in meaning;theword malamiko therefore means "enemy", and the word "malbela" therefore means "ugly" in Zamenhof's language. In 1887, Zamenhof wrote a description of this language and published it. He used a pen name, Dr. Esperanto, when signing the book. He selected the name Esperanto because this word means "a person who hopes" in his language. Esperanto clubs began popping up throughout Europe, and by 1950, Esperanto had spread from Europe to America and Asia. In 1905, the First World Congress of Esperanto took place in France, with approximately 700 attendees from 20 different countries. Congresses were held annually for nine years, and 4,000 attendees were registered for the Tenth World Esperanto Congress scheduled for 1914, when World War I erupted and forced its cancellation. Esperanto has had its ups and downs in the period since World War I. Today, years after it was introduced, it is estimated that perhaps a quarter of a million people are flent in it. This may seem like a large number, but it is really quite small when compared with the billion English speakers and billion Mandarin Chinese speakers in in today's world. Current advocates would like to see its use grow considerably and are taking  steps to try to make this happen.

Many scientists believe our love of sugar may actually be an addiction. When we eat or drink sugary foods, the sugar enters our blood and affects parts of our brain that make us feel good. Then the good feeling goes away, leaving us wanting more. All tasty foods do this, but sugar has a particularly strong effect. In this way, it is in fact an addictive drug, one that doctors recommend we all cut down on. “It seems like every time I study an illness and trace a path to the first cause, I find my way back to sugar,” says scientist Richard Johnson. One- third of adults worldwide have high blood pressure, and up to 347 million have diabetes. Why? "Sugar, we believe, is one of the culprits, if not the major culprit," says Johnson. Our bodies are designed to survive on very little sugar. Early humans often had very little food, so our bodies learned to be very efficient in storing sugar as fat. In this way, we had energy stored for when there was no food. But today, most people have more than enough. So the very thing that once saved us may now be killing us. So what is the solution? It’s obvious that we need to eat less sugar. The trouble is, in today’s world, it’s extremely difficult to avoid. From breakfast cereals to after-dinner desserts, our foods are increasingly filled with it. Some manufacturers even use sugar to replace taste in foods that are advertised as low in fat. But there are those who are fighting back against sugar. Many schools are replacing sugary desserts with healthier options like fruit. Other schools are growing their own food in gardens, or building facilities like walking tracks so students and others in the community can exercise. The battle has not yet been lost.  
4. According to the passage, why is it so hard to avoid sugar?

Human beings are plagued by all kinds of diseases and millions of people die from them. Many of these diseases such as diabetes, polio, whooping cough and diphtheria can be fatal and in the past, people used to die from them. However, with modern technology and a lot of research, scientists and doctors have come up with various ways to cure these diseases, and consequently, many lives are saved. In doing the medical research, doctors have come face to face with many problems. One such problem is the opposition that comes from animal activists. They are against the inhuman treatment of animals. They argue that in conducting their medical research, doctors put animals through a very painful process and this should be stopped. According to the fiercest animal activists, nothing justifies the use of animals in medical experiments, even if lives might be saved. To get their message across, animal activists are even willing to resort to the use of violence. Many animal protection groups, like the Animal Liberation Front (ALF), have broken into laboratories illegally to ‘rescue’ animals. They take away whatever animals they can find and free them. These people also make their case by threatening the researchers. They vandalize medical equipment, and in the most serious cases, they even . In stealing the animals, the activists are actually hindering the progress of medicine. In many cases, the animals were part of research for the cure for various diseases and visual defects in babies. Cures for problems that people face, therefore, come slower and in the waiting period, more people die. Researchers have come up with many cures in the process of working with animals and on animals. Organ transplants are so common today, but we forget that they became only  possible after they were tested on animals. Doctors were able to come up with a cure for river blindness, a disease that affects millions of people in South America and Africa. These are only a few examples, and there are many more. In spite of what animal activists think, most researchers do not treat animals cruelly. In fact, mistreated animals which are in agony will affect the quality of research so that results obtained are not really reliable. Thus, researchers do try to treat animals as well as possible. In the long run, animal activists can cause serious damage to the future of medicine. With their persistent campaigning, much of the public supports their cause. People with AIDS or cancer need doctors to do research to save their lives, and often it is a case where animal research is crucial before any cure can be found

The International Ecotourism Society (TIES), a non-profit organization committed to promoting sustainable tourism, states that ecotourism unites conservation and communities with sustainable travel. With that being said, they offer six core principles of ecotourism that vacationers should follow: minimize impact, build environmental and cultural awareness and respect, provide positive experiences for both visitors and hosts, provide direct financial benefits for conservation, provide financial benefits and empowerment for local people, and raise sensitivity to host countries’ political, environmental, and social climate. Ecotourism offers the opportunity to help protect and maintain our planet. Beginning with responsible travel, sustainable tourism promotes green practices such as recycling and using organic products. There are also many environmental programs and initiatives made available so that people can get involved with sustainability. For example, in Kenya, tourists can get involved with the Basecamp Foundation, which has a monitoring program for big cats and elephants. These kinds of experiences try to demonstrate the positive impact of tourism and teach tourists about the significance of maintaining the environment. However, the simple act of being a tourist in a fragile, natural area helps a great deal, as the money spent there assists in raising funds to protect those areas for generations. Sustainable tourism supports local communities by allowing their economy to grow. Tourism alone employs a large number of local staff. This in turn empowers communities to fight against poverty and encourages the support of local events, festivals, and organizations. As a result the community and its local businesses thrive.  Not only is ecotourism an environmentally fun experience, but it’s also educational. By embarking on an ecotourism vacation, people gain an awareness and understanding of the social and economic conditions of the place they visit. In addition, vacationers learn to appreciate the area’s environment through conservation and also to respect the culture of the local people. While tourists are normally unaware of a country’s poverty or ill conditions, ecotourism strives to expose tourists to the realities of these areas. Ecotourism is a new holiday experience that mixes together vacation fun with conservation and education. Sustainable tourism creates environmentally aware individuals and helps develop their appreciation of nature and local culture. Not only do vacationers go home with new knowledge, but also a worthwhile experience.

Read the following passage and choose the best answer (A, B, C, D):
What results in good health and longevity? It’s good genes, good lifestyle and good luck. But since we can’t choose our parents, or know what fate holds in store for us, we must treat lifestyle with tender, loving care. Now, a report “Circulation” proves that a sound lifestyle adds 12 to 14 more years to life. For instance, a woman, aged 50, who follows these lifestyle rules can expect to live to 93 years. This compares to a woman who indulges in an unhealthy lifestyle and dies at 79. In men, the increase in longevity from a healthy lifestyle is from 76 to 88 years. In the general population, the U.S. spends more money on health care than any other country. So why are so many people in North America suffering from ill health? It is quite apparent that the epidemic of obesity, type 2 diabetes and heart attack will continue to be the big killers. At the moment there is little evidence this battle is being won. But a study that followed both staff and students at the University of Liverpool shows it’s not an impossible dream. In its first experiment, female diners were randomly divided to receive either a small or large quiche for lunch. The next day, the same group were all allowed to serve themselves any portion they desired. Researchers discovered the ones who had been served the smaller portion, tended to choose the smaller portion. A second experiment tested male diners and it produced the same result. In the third experiment both sexes were included, but it was done one week later. This time diners were asked to look at various photos of portion size and asked which looked normal. Those who were previously given the smaller portions considered the smaller ones normal.  These studies showed that it is possible to shift people from what they think is a normal portion to what is actually the proper amount to eat. And that the perception of what is normal lasts at least to one week later. Remember, a voyage of a thousand miles begins with the first step. The same philosophy applies to longevity. So, gradually incorporate one thing at a time into your lifestyle. Don’t forget the importance of smaller portions, add more fruits and vegetables, buy a pedometer to check the number of steps taken each day, and to measure your progress, step on the scale every day

A considerable body of research has demonstrated a correlation between birth order and aspects such as temperament and behavior, and some psychologists believe that birth order significantly affects the development of personality. Psychologist Alfred Adler was a pioneer in the study of the relationship between birth order and personality. A key point in his research and in the hypothesis that he developed based on it was that it was not the actual numerical birth position that affected personality; instead, it was the similar responses in large numbers of families to children in specific birth order positions that had an effect. For example, first-borns, who have their parents to themselves initially and do not have to deal with siblings in the first part of their lives, tend to have their first socialization experiences with adults and therefore tend to find the process of peer socialization more difficult. In contrast, later-born children have to deal with siblings from the first moment of their lives and therefore tend to have stronger socialization skills.

Numerous studies since Adler's have been conducted on the effect ofbirth order and personality. These studies have tended to classify birth order types into four different categories: first-born, second-born and/or middle, last, and only child.

Studies have consistently shown that first-born children tend to exhibit similar, positive and negative personality traits. First-borns have consistently been linked with academic achievement in various studies; in one study, the number of National Merit scholarship winners who are first- borns was found to be equal to the number of second-and third-borns combined. First-borns have been found to be more responsible and assertive than those born in other birth-order positions and tend to rise to positions of leadership more often than others; more first-borns have served in the u.s. Congress and as u.s. presidents than have those born in other birth-order positions. However, studies have shown that first-borns tend to be more subject to stress and were considered problem children more often than later-borns.

Second-born and/or middle children demonstrate markedly different tendencies from first- borns. They tend to feel inferior to the older child or children because it is difficult for them to comprehend that their lower level of achievement is a function of age rather than ability, and they often try to succeed in areas other than those in which their older sibling or siblings excel. They tend to be more trusting, accepting, and focused on others than the more self-centered first-borns, and they tend to have a comparatively higher level of success in team sports than do first-borns or only children, who more often excel in individual sports.

The last-born child is the one who tends to be the eternal baby of the family and thus often exhibits a strong sense of security. Last-borns collectively achieve the highest degree of social success and demonstrate the highest levels of self-esteem of all the birth-order positions. They often exhibit less competitiveness than older brothers and sisters and are more likely to take part in less competitive group games or in social organizations such as sororities and fraternities.

Only children tend to exhibit some of the main characteristics of first-borns and some of the characteristics of last-borns. Only children tend to exhibit the strong sense of security and self-esteem exhibited by last-borns while, like first-borns, they are more achievement oriented and more likely than middle-or last-borns to achieve academic success. However, only children tend to have the most problems establishing close relationships and exhibit a lower need for affiliation than other children.
