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.

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

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:
Accustomed though we are to speaking of the films made before 1927 as “silent”, the film has never been, in the full sense of the word, silent. From the very beginning, music was regarded as an indispensable accompaniment; when the Lumiere films were shown at the first public film exhibition in the United States in February 1896, they were accompanied by piano improvisations on popular tunes. At first, the music played bore no special relationship to the films; an accompaniment of any kind was sufficient. Within a very short time, however, the incongruity of playing lively music to a solemn film became apparent, and film pianists began to take some care in matching their pieces to the mood of the film.
As movie theaters grew in number and importance, a violinist, and perhaps a cellist, would be added to the pianist in certain cases, and in the larger movie theaters small orchestras were formed. For a number of years the selection of music for each film program rested entirely in the hands of the conductor or leader of the orchestra, and very often the principal qualification for holding such a position was not skill or taste so much as the ownership of a large personal library of musical pieces. Since the conductor seldom saw the films until the night before the y were to be shown (if, indeed, the conductor was lucky enough to see them then), the musical arrangement was normally improvised in the greatest hurry.
To help meet this difficulty, film distributing companies started the practice of publishing suggestions for musical accompaniments. In 1909, for example, the Edison Company began issuing with their films such indications of mood as “pleasant’, “sad”, “lively”. The suggestions became more explicit, and so emerged the musical cue sheet containing indications of mood, the titles of suitable pieces of music, and precise directions to show where one piece led into the next.

Certain films had music especially composed for them. The most famous of these early special scores was that composed and arranged for D. w. Griffith’s film Birth of a Nation, which was released in 1915.

Which of the following notations is most likely to have been included on a musical cue sheet of the early 1900's?

Sophia is a humanoid robot developed by Hong Kong-based company Hanson Robotics. She has been designed to learn and adapt to human behavior and work with humans, and has been interviewed around the world. In October 2017, she became a Saudi Arabian citizen, the first robot to receive citizenship of a country. According to herself, Sophia was activated on April 19, 2015. She is modeled after actress Audrey Hepbum,and is known for her human-like appearance and behavior compared to previous robotic variants. According to manufacturer, David Hanson, Sophia has artificial intelligence, visual data processing and facial recognition. Sophia also imitates human gestures and facial expressions and is able to answer certain questions and to make simple conversations on predefined topics (e.g. on the weather). The robot uses voice recognition technology from Alphabet Inc. (parent company of Google) and is designed to get smarter over time. Sophia’s intelligence software is designed by SingularityNET. The AI program analyses conversations and extracts data that allows her to improve responses in the future. It is conceptually similar to the computer program ELIZA, which was one of the first attempts at simulating a human conversation. Hanson designed Sophia to be a suitable companion for the elderly at nursing homes, or to help crowds at large events or parks. He hopes that she can ultimately interact with other humans sufficiently to gain social skills. Sophia has been interviewed in the same manner as a human, striking up conversations with hosts. Some replies have been nonsensical, while others have been impressive, such as lengthy discussions with Charlie Rose on 60 Minutes. In a piece for CNBC, when the interviewer expressed concerns about robot behavior, Sophia joked that he had “been reading too much Elon Musk, and watching too many Hollywood movies”. Musk tweeted that Sophia could watch The Godfather and suggested “What’s the worst that could happen?”. On October 11, 2017, Sophia was introduced to the United Nations with a brief conversation with the United Nations Deputy Secretary-General, Amina J. Mohammed. On October 25, at the Future Investment Summit in Riyadh, she was granted Saudi Arabian citizenship, becoming the first robot ever to have a nationality. This attracted controversy as some commentators wondered if this implied that Sophia could vote or marry, or whether a deliberate system shutdown could be considered murder. Social media users used Sophia’s citizenship to criticize Saudi Arabia’s human rights record.

Spend just a minute watching the world population counter tick up on Worldometers and you’ll see just how quickly we’re swelling in numbers. The current figure stands at around 7.7 billion, and this is projected to become 9.8 billion by 2050, according to the UN. More people means more carbon footprints - more cars, waste and emissions, more houses and infrastructure to be constructed using the world’s limited resources, more mouths to be fed using more water and energy in food production. Governments recognise the severity of the situation and have mostly come together over global policies like the UN’s Paris Agreement, to limit carbon emissions and their impact on climate change. In addition, new technologies are being developed to make our use of resources more efficient. As for controlling population growth, the education of women is one key factor. Research shows the higher level to which a woman is educated, the fewer children she is likely to have. In Ghana, for example, women who have been to high school, have a fertility rate of between two and three children, compared with six for those who have no education. This could be for several reasons including learning about desired family size and understanding child health better. This means that the mother is more confident her children will survive. She is also likely to hold more sway within the family, arguing for fewer children if that is what she wants.  There is also plenty that individuals can do to reduce their personal footprint. Earth Overshoot Day is defined as the day when humanity has used up nature’s resource budget for the year. The Global Footprint Network calculates that moving Earth Overshoot day back by five days every year would mean that, by 2050, we’d be using the resources of less than one planet. Just eating 50% less meat and replacing it with vegetarian alternatives could save the planet five days. As David Attenborough says, if we want to save Earth, we can no longer afford to keep eating meat: “We are omnivores, so biologically, if you could have a biological morality, you can say, yes we evolved to eat pretty well everything. But now we’ve got to a stage in our own social evolution in which that is no longer practical.” Sir David says he himself now eats less meat and is bolstered by the knowledge that it’s helping the planet.

Bagpipe music played, wreaths were sent and Amazing Grace was sung. A  black shroud was laid upon a makeshift urn. It was a funeral, of course, for which such displays of respect are common. But in this case, the people living in a small Nova Scotia community had gathered to pay their respects not to a person who had died, but to a post office.  The grief might have been hard for outsiders to understand, but not for those living in Head of St. Margaret’s Bay, N.S., where the post office run by Verna Dunlop was a big part of their small, tight-knit community. The post office, which had been located in the back of Dunlop’s home, was not just a utilitarian service kiosk where residents had to go to pick up their mail. According to locals, it was also a community hub where people gathered to catch up on the town gossip, or to enjoy a cup of the coffee the postmaster had been brewing for them. “It’s really the centre of the village,” said one woman, explaining what the post office meant to the people living there.  There had been a post office located in Head of St. Margaret’s Bay since before Confederation. And local residents spent months fighting to keep the one they had. But Canada Post made the decision to close it, as it was losing money. It was replacing the post office with sets of newly installed super mailboxes.  Many people in town weren’t convinced the coming changes were for the better. “We do not want those super mailboxes. We want to have a community life,” he said. At the mock funeral, Dunlop choked up as she said she hoped “this is going to stop,” alluding to the fact that it wasn’t just Head of St. Margaret’s Bay that was losing its post office. “We hope that the way of life that we’re used to we can keep,” she added. Canada Post had closed 40 such rural post offices that year and had long-term plans to close more than 5,000 of them across the country. “Just as Verna Dunlop’s post office came to symbolize for these people the best qualities of rural life, so does its passing remind them of the steady erosion of that way of life,” said Evans.

Read the following passage and choose the best answer (A, B, C, D):
A special education teacher is someone who works with children and youths who have a variety of disabilities. Special education teachers are patient, understanding educators dedicated to giving each individual student the tools and guidance needed to help them maximize success. As schools become more inclusive, special education teachers and general education teachers increasingly work together in general education classrooms. Special education teachers help general educators adapt curriculum materials and teaching techniques to meet the needs of students with disabilities. They coordinate the work of teachers, teacher assistants, and related personnel, such as therapists and social workers, to meet the individualized needs of the student within inclusive special education programs. Special education teachers work in a variety of settings. Some have their own classrooms and teach only special education students; others work as special education resource teachers and offer individualized help to students in general education classrooms; still others teach together with general education teachers in classes including both general and special education students. Some teachers work with special education students for several hours a day in a resource room, separate from their general education classroom. Considerably fewer special education teachers work in residential facilities or tutor students in homebound or hospital environments. The work also can be emotionally demanding and physically draining. Many special education teachers are under considerable stress due to heavy workloads and administrative tasks. They must produce a substantial amount of paperwork documenting each student’s progress and work under the threat of litigation against the school or district by parents if correct procedures are not followed or if the parents feel that their child is not receiving an adequate education. Recently passed legislation, however, is intended to reduce the burden of paperwork and the threat of litigation.

Read the following passage and choose the best answer (A, B, C, D):
Frenchman Edouard de Laboulaye first proposed the idea of a monument for the United States in 1865. Ten years later sculptor Frederic Auguste Bartholdi was commissioned to design a sculpture with 1876 in mind for completion, to commemorate the centennial of the American Declaration of Independence. The Statue was named “Liberty Enlightening the World” and was a joint effort between America and France. It was agreed that the American people were to build the pedestal, and the French people were responsible for the Statue and its assembly here in the United States. However, lack of funds was a problem on both sides of the Atlantic Ocean. In France, public fees, various forms of entertainment, and a lottery were among the methods used to raise funds. In the United States, benefit theatrical events, art exhibitions, auctions and prizefights assisted in providing needed funds. Poet Emma Lazarus wrote her famous sonnet “The New Colossus” in 1883 for the art and literary auction to raise funds for the Statue’s pedestal. Meanwhile in France, Bartholdi required the assistance of an engineer to address structural issues associated with designing such a colossal copper sculpture. Alexandre Gustave Eiffel (designer of the Eiffel Tower) was commissioned to design the massive iron pylon and secondary skeletal framework which allows the Statue’s copper skin to move independently yet stand upright Back in America, fundraising for the pedestal was going particularly slowly, so Joseph Pulitzer opened up the editorial pages of his newspaper, “The World,” to support the fund raising effort. Pulitzer used his newspaper to criticize both the rich who had failed to finance the pedestal construction and the middle class who were content to rely upon the wealthy to provide the funds. Pulitzer’s campaign of harsh criticism was successful in motivating the people of America to donate. Architect Richard Morris Hunt designed the Statue of Liberty’s granite pedestal in 1884, donating his fee to help fund the Statue. Financing for the pedestal was completed in August 1885, and pedestal construction was finished in April 1886. The Statue was completed in France in July 1884 and arrived in New York Harbor in June 1885 onboard the French frigate “Isere.” In transit, the Statue was reduced to 350 individual pieces and packed in 214 crates. The Statue was reassembled on her new pedestal in four months’ time. On October 28, 1886, President Grover Cleveland oversaw the dedication of the Statue of Liberty in front of thousands of spectators. She was a centennial gift ten years late

Read the following passage and choose the best answer (A, B, C, D):
Once restricted to space stations and satellites, photovoltaics are now gaining popularity and becoming an increasingly viable option. Every day, the sun releases an enormous amount of energy, far more than the entire population consumes. Being that the sun is a sustainable, renewable, and inexhaustible source for generating electricity, not using it seems almost counter-intuitive, especially considering the social and environmental impacts of other forms of energy generation. But the technology to create electricity from the sun is by no means simple and still has some limitations, the most significant being price. The process of turning the sun’s rays into electrical energy all starts in the so-called photovoltaic cell. These cells are produced with two chemically altered silicon layers of which one is missing elections and the other is electron-overloaded. When the photons from the sunlight reach the surface, these electrons gain the ability to move, generating a flow that creates an electric current. Each cell generates a small amount of energy and a panel is usually made of between 36 and 72 photovoltaic cells. By connecting several panels together, a photovoltaic system is created. Eight to ten panels is enough to power a small house. Evidently, however, this statistic is influenced by some factors, such as the efficiency of the panels, the amount of sunshine in the region, and the energy demand of the residence itself.  Importantly, photovoltaic solar panels produce electricity in the form of direct current, meaning the electricity must pass through an inverter to transform it into alternating current - which is what is normally used in buildings, appliances, sockets, and light bulbs. Photovoltaic systems can facilitate energy generation in remote locations where infrastructural networks do not reach. In these cases, the system uses batteries to store electricity when less energy is used than is consumed, such as at night or on very cloudy days. However, it is also possible to use photovoltaics in systems connected to the power grid. In these cases, the excess energy goes to the electricity grid, creating energy “credits” for the building in question. In some countries, it is even possible to sell surplus energy, making the building a power plant for neighbors and method of paying off the investment more quickly.

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
