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.

- A. the cultivation of a plant or garden by a community
- B. one's acquaintance with literature and art

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:

About 1500 miles long, this unique wall stretches from the Gulf of Chili of the Yellow 9০৪ along the northern frontier of China to Kans Province in the west. The width of this wall varies from 15 to 40 feet at the base, and from 12 to 35 feet at the summit. Its height ranges from 20 to 50 feet. This is the only structure on the earth that can be identified from the moon. Walled frontier between the kingdoms in China date from at least the 4th century BC. in the 3rd century BC, the first emperor of 'Ch 'in', after uniting China, linked up the existing walls and built new sections to create the Great Wall as a continuous unit. His purpose was to defend China from the Huns on the north. Watch towers and garrison stations were set at regular intervals in order to Send signals and guard the bulwark. The wall was constructed in such a way that troops summoned by beacon fire could be quickly 10 transported along its top. The wall was built mostly of rubble, although the western sections are of tamped earth and important passes are of brick or masonry. The wall was frequently modified in later centuries. Some of its sections were built in the 15th and 16th centuries with new facilities of high towers. Before that, extensive repairs and extensions were made at various periods, notably during the Ming dynasty. 1.Which of the following is INCORRECT?

230 . As books go digital, new questions, both philosophical and commercial arise. How, physically, will people read books in future? Will technology 'unbind' books, as it has unbundled other media, such c. as music albums? Will reading habits change as a result? Change is least likely in the physical medium of books. Electronic books do exist, but they cannot and will not replace the print book. Perhaps some people will read electronic books if only to 'taste' them, but most of us will continue to buy them in paper; form or borrow them from a library. For sure, fiction will never'. find a better medium than the physical book. Readers immersed in a storyline want above all not to be interrupted and want to read novels in an unhurried way. And, of course, they will continue to read print books for the sheer pleasure of owning them and for leisurely reading. 1.'Leisurely' in line 12 has been uses as:

701 . 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
