Formulating appropriate mechanism for the implementation of the children Act 2013 has become an urgent need to improve the legal protection of children.

337 . Many people think that Big Ben is the huge clock that towers 316 feet above the River Thames at Westminster. But strictly the deep-voiced bell which booms from the belfry at the top of 336 steep stairs. For fifteen years. in the last century, experts wrangled about the plans for parliament's prospective clock. Filially, Frederick Dent was appointed to make his masterpieces. But even then the job was not plain sailing. The original bell was cast in 1856, dragged over Westminster Bridge by sixteen white horses and hung on gallows in New Palace Yard for testing. Sadly, a crack was discovered, and the bell has to be re-cast. But, even today, a crack is still apparent. However, it is good to remember that although Big Ben was born in the controversy he was christened with laughter. During a House of Commons debate on a suitable name for London's new timekeeper, along speech was made by an immense member called out' 'why not call the clock Big Ben? 'So, in a good-humored roar. The thirteen and a-half -ton heavyweight was named for all time, and began public service in May 1859. Choose the right sentence that will give the right information .
- A. Big Ben is really a clock
- B. Big Ben is really a bell
- C. Big Ben is a belfry
- D. Big Ben is a river

805 . The practice of Naturopathy can be traced back to over 1000 years to the time of Hippocrates, who is known as the father of medicine (460 BC to 357 BC). He considered diseases to be an effect of imbalanced in such natural elements as air, water, sunshine, and nourishment. As the name suggests, Naturopathy is the treatment or prevention of disease without a drug, use natural therapies like changes in diet and lifestyle. It is based on the belief that the body is self-healing and has the ability to repair itself and recover from illness if in a healthy environment. Naturopathy also deems that the power of restore health lies not in drug but in nature. The modern medical system, on the other hand, depends on drugs, it treats the symptom and suppresses the disease, but often does little to ascertain the real root of the problem. Naturopathy seeks to find the cause of the symptom and then treats it with natural changes based on individual requirement. According to this type of fo therapy, physical problems are invariably a result of emotional imbalances caused by the stress of modern life. Yet another cause of the disease is the accumulation of waste and toxins in the body consequently, a basic foundation of Naturopathy is that the mind, body, and soul are interconnected and cannot be treated in isolation. 1. All of the following are true of Naturopathy except:
- A. Naturopathy is an ancient medical system
- B. Naturopathy gives stress to diet
- C. Naturopathy is based on the study of patient's symptoms
- D. Naturopathy considers modern lifestyle to be a root of physical problems

By culture, (L3) one means first of all what the anthropologists mean, the way of life of a particular people (L4) living together in one place. That culture is made visible in their arts, in their social system, in (L5) their habits and customs, in their religion. It is and aggregate of customsinstitutions, manners, (L6) standards, testes, morals and beliefs. Now, these are transmitted rather by the family than by (L7) the school , hence when family life fails to play is part, we must expect our culture to (L8) deteriorate (L9) It is a delusion to think that the maladies of the modern world can be put right by a system of (L10) instruction. on the contrary, universal education, by lowering standards, morals and tastes to (L11) a common denominator and by sharpening the wits rather than disciplining character, tends to (L12) break down existing cheeks and balances. Education should be the drawing forth of potential (L13) values, it should not be the destruction of the safeguards that tradition place around young (L14) egos naturally inclined to wilful and precarious flights. (L15) 1.The writer uses the term ‘culture’ to refer to-
- A. the cultivation of a plant or garden by a community
- B. one's acquaintance with literature and art
- C. one's acquisition of knowledge

993 . Rad the passage below and choose the alternative A, B, C or D to answer the questions (18-23) Washington was the first city in history to be created solely for the purpose of governance. Following the Revolution, members of congress had hotly debated the question of a permanent home for themselves and for those departments- the Treasury, the patent Office, and so on - Which even the sketchiest of central governments would feel obliged to establish. In 1790, largely in order to put an end to congressional bickering, George Washington was charged with selecting a site for the newly designated federal district. Not much to anyone's surprise but to the disappointment of many, he chose a tract of land on the banks of the Potomac River, a few miles upstream from his beloved plantation Mount Vernon. The District of Columbia was taken in part from Virginia and in part from Maryland. at the time is was laid out, its hundred square miles consisted of gently rolling hills, some under cultivation and the rest heavily wooded, with a number of creeks and much swampy land along the Potomac. There is now a section of Washington that is commonly referred to as Foggy Bottom; that section bore the same nickname a hundred and eighty years ago. two port cities, Alexandria and Georgetown, flourished within sight of the new capital and gave is access by ship to the most important cities of the infant nation- Charleston, Baltimore, Philadelphia, New York, Newport, Salem and Portsmouth- and also to the far- off ports of England and the Continent. 16.Why was George Washington's choice for the site of the - capital not very surprising?
- A. George Washington had lived on the site before the American Revolution.
- B. The river would bring trade to the city.
- C. The site was very close to George Washington's own home.
- D. The member of Congress hade already state there preference for the site.

996 . The First Amendment to the American Constitution declares o freedom of the press to all people. Although this right was not officially adopted until 179 l , the famous Zenger trial of 1735 laid the groundwork for insuring this precious freedom. .73 John Peter Zenger emigrated as a teenager from Germany. In 1733, he began publishing the New York Weekly journal. The o following year, he was arrested for writing a story about the crown-appointed governor of New York. While Zenger was imprisoned for nine months, his wife dutifully published the newspaper 1--3 everyday, bravely telling the truth about the corrupt government officials sent by the king to govern the colonies. Finally Zenger's long-awaited trial took place. The hostile judge dismissed Zenger's -5' local lawyers, making it necessary for his wife to seek out Andrew o Hamilton, a prominent Philadelphia lawyer. Persuaded by ; Hamilton, the jury bravely returned a not-guilty verdict, defying the judge's orders for a conviction. As a result of determination and bravery on the part of the colonists, a lasting victory for freedom of ' the press was gained by immigrant. 1.John Peter Zenger was a ________

1060 . The Ebola outbreak in West Africa is the world's deadliest to date and the World Health Organization has declared an international health emergency. It is known that Ebola virus was first recognized in 1976 in Zaire (now the Democratic Republic of Congo) in an outbreak that affected 318 people and resulted in 280 deaths. The virus affects humans and non -human primates, but the natural reservoir of Ebola is still unknown. Scientists believe Ebola spreads through zoonotic transmission, and the symptoms of Ebola are somewhat nonspecific at first. The first patient of an Ebola outbreak is thought to be infected through contact with an infected animal. From there, the virus can spread to other humans through direct contact with blood or body fluids. Within 2-21 days of exposure, patients usually experience fever, headache, joint and muscle aches, sore throat and weakness, later followed by diarrhoea, stomach pain and in some cases both internal and external bleeding. Strict medical infection control and rapid burial are regarded as the means of prevention o the disease. 1.The closest meaning of 'zoonotic transmission' is-
- A. coming from a monkey

It also hurts democracy by undermining the principles of fair play and justice. Instead of contracts being awarded on the basis of fair competition relying on price, quality, and innovation, they are awarded as a result of competitive bribery. The consequences are dire. Investors keep away and trade suffers. Transparency International (TI) defines corruption as the use of public office for private gain. Decisions are made not for public benefit but for private interests. Costs Incurred are high and prestigious projects are favored - over cost-efficient development projects. Access to basic social and economic rights such as education, 3medical care, adequate shelter, and clean water are jeopardized. The environment is threatened and human rights abuse flourishes. When . corruption increases, regimes become more secretive, less tolerant of; dissent and more fearful of the loss of power. TI believes that the stamping out of corruption is not the responsibility of any one agency but the responsibility of all parties concerned. Every section of society must pitch in because corruption affects everyone, especially the poor.

2791 . Read the following passage carefully and then choose the appropriate answers to the questions: Napoleon Bonaparte's ambition to control all the area around the Mediterranean Sea led him and his French soldiers to Egypt. After losing a naval battle, they were forced to remain there for three years. In 1799, while constructing a fort, a soldier discovered a piece of stele (stone pillar bearing an inscription) known as the Rosetta stone. This famous stone, which would eventually lead to the deciphering of ancient Egyptian hieroglyphics dating to 3100 B.C., was written in three languages: hieroglyphics (picture writing), demotic (a shorthand version of hieroglyphics), and Greek, Scientists discovered that the characters, unlike those in English, could be written from right to left and in other directions as well. Twenty-three years after discovery of the Rosetta stone, Jean Francois Champollion, a French philologist, fluent in several languages, was able to decipher the fast word - Ptolemy --- name of an Egyptian ruler. This name was written inside an oval called a "cartouche". Further investigation revealed that cartouches contained names of important people of that period. Champollion painstakingly continued his search and was able to increase his growing list of known phonetic signs. He and an Englishman, Thomas Young, worked independently of each other to unravel the deeply hidden mysteries of this strange language: Young believed that sound values could be assigned to the symbols, while Champollion insisted that the pictures represented words. Who was responsible for deciphering the first word?
- A. Champollion

3882 . To find the sets X and Y based on the given information, we need to interpret the provided conditions step by step. ### Given: 1. X ∪ Y = { 1 , 2 , 3 , 5 , 6 , 8 , 9 , 10 } 2. X ∩ Y = { 1 , 5 } 3. Y − X = { 2 , 6 , 9 , 10 } ### Step 1: Using Y − X From condition 3, we know that: Y − X = { 2 , 6 , 9 , 10 } This means that the elements 2 , 6 , 9 , and 10 are in Y but not in X . Therefore, we can express Y as: Y = ( Y − X ) ∪ ( X ∩ Y ) Since X ∩ Y = { 1 , 5 } , we can write: Y = { 2 , 6 , 9 , 10 } ∪ { 1 , 5 } = { 1 , 2 , 5 , 6 , 9 , 10 } ### Step 2: Using X ∪ Y Now, we know: X ∪ Y = { 1 , 2 , 3 , 5 , 6 , 8 , 9 , 10 } And we have Y = { 1 , 2 , 5 , 6 , 9 , 10 } . Now we can find X : X = ( X ∪ Y ) − Y This gives us: X = { 1 , 2 , 3 , 5 , 6 , 8 , 9 , 10 } − { 1 , 2 , 5 , 6 , 9 , 10 } Calculating this, we get: X = { 3 , 8 } ### Step 3: Verification Now we need to verify if the derived sets satisfy all the conditions. - **Checking X ∪ Y **: X ∪ Y = { 3 , 8 } ∪ { 1 , 2 , 5 , 6 , 9 , 10 } = { 1 , 2 , 3 , 5 , 6 , 8 , 9 , 10 } (True) - **Checking X ∩ Y **: X ∩ Y = { 3 , 8 } ∩ { 1 , 2 , 5 , 6 , 9 , 10 } = { 1 , 5 } (True) - **Checking Y − X **: Y − X = { 1 , 2 , 5 , 6 , 9 , 10 } − { 3 , 8 } = { 2 , 6 , 9 , 10 } (True) ### Conclusion Thus, the sets X and Y are: X = { 3 , 8 } Y = { 1 , 2 , 5 , 6 , 9 , 10 }

The deadlock involves a circular “hold-and-wait” condition between two or more processes, so “one” process cannot hold a resource, yet be waiting for another resource that it is holding.
