Blake went on to develop an intensely person art which drew upon a range of literary, mythical and biblical sources to expound a unique and mysterious vision.

375 . 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

884 . 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

980 . Influenza, or flu, is a virus that attacks the respiratory system. The flu virus is highly contagious: when an infected person coughs, sneezes or talks, respiratory droplets are generated and transmitted into the air, and can then be inhaled by anyone nearby. Additionally, a person who touches something with the virus on it and then touches his or her mouth, eyes or nose can become infected. Before COVID-19, the most severe pandemic in recent history was the 1918 influenza virus, often called "the Spanish Flu". The virus infected roughly 500 million people - one-third of the world's population - and caused SO million deaths worldwide (double the number of deaths in World War I). In the United States, a quarter of the population caught the virus, 675,000 died, and life expectancy dropped by 12 years. With no vaccine to protect against the virus, people were urged to isolate, quarantine, practice good personal hygiene, and limit social interaction. The first observations of illness and mortality were documented in the United States (in Kansas) in March 1918 and then in April in France, Germany and the United Kingdom. To maintain morale, World War I censor minimized these early reports. Newspapers were free to report the epidemic'seffects in neutral Spain, such as the grave illness of King Alfonso XIII, and these stories created a false impression of Spain as especially hard hit. This gave rise to the name "Spanish Flu". Until February 2020, the 1918 epidemic was largely overlooked in the teaching of American history, despite the ample documentation at the National Archives and elsewhere of the disease and its devastation. The 100-year-old pictures from 1918 that just months ago seemed quaint and dated now seem oddly prescient. 1.The word 'quarantine 'in line 11 can be replaced by:
- A. caging
- B. distancing
- C. socializing
- D. closeness

Read the passage below and then choose the alternative A, B, C or D to answer the question: The Man Booker Prize of Fiction is awarded every year for a novel written in the English language and published in the common wealth countries and Ireland and it aims to represent the very pest in contemporary fiction. The Prize was orginally called the Booker-McConnell Prize, which was the name of the company that sponsored it, though it was better-known as simply the 'Booker Prizw'. In 2002, the Man Group became the sponsor and they chose the new name, keeping 'Booker'. Line 5 Publishers can submit books for consideration for the prize, but the judges can also ask for books to be submitted they think should be included. Firstly, the Advisory Committee gives advice if there have been any changes to the rules for the prize and selects the people who will hudge the books. The judging panel changes every year and usually a person can be a judge once only. 10 Great efforts are made to ensure that the judging panel is balanced in terms of gender and professions within the industry, so that a writer, a critic, an editor and an academic are chosen along with a well-known person from wider society. However, when the panel of judges had been finalized, they are left to make their own decisions without any further involvement or interference from the prize spomsor. 15 The Man Booker judges include critics, writers and academic to maintain the consistent quality of the prize and its influence is such that the winner will almost certainly see the sales increase considerably, in addition to the $50.000 that comes with the prize. 20 1.Books can be submitted--.

985 . 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.

2982 . Influenza, or flu, is a virus that attacks the respiratory system. The flu virus is highly contagious: when an infected person coughs, sneezes or talks, respiratory droplets are generated and transmitted into the air, and can then be inhaled by anyone nearby. Additionally, a person who touches something with the virus on it and then touches his or her mouth, eyes or nose can become infected. Before COVID-19, the most severe pandemic in recent history was the 1918 influenza virus, often called "the Spanish Flu". The virus infected roughly 500 million people - one-third of the world's population - and caused SO million deaths worldwide (double the number of deaths in World War I). In the United States, a quarter of the population caught the virus, 675,000 died, and life expectancy dropped by 12 years. With no vaccine to protect against the virus, people were urged to isolate, quarantine, practice good personal hygiene, and limit social interaction. The first observations of illness and mortality were documented in the United States (in Kansas) in March 1918 and then in April in France, Germany and the United Kingdom. To maintain morale, World War I censor minimized these early reports. Newspapers were free to report the epidemic'seffects in neutral Spain, such as the grave illness of King Alfonso XIII, and these stories created a false impression of Spain as especially hard hit. This gave rise to the name "Spanish Flu". Until February 2020, the 1918 epidemic was largely overlooked in the teaching of American history, despite the ample documentation at the National Archives and elsewhere of the disease and its devastation. The 100-year-old pictures from 1918 that just months ago seemed quaint and dated now seem oddly prescient. The phrase 'hard hit'in line 18 means -
- A. to his strongly
- B. to heat very hard
- C. to hardly suffer
- D. to be adversely affected

3679 . 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 }
