Read the following article and select the best answer. Article: The 1920s was a decade of wealth, decadence and social changes. They were known as the Roaring Twenties, and the best place to experience this exciting time was New York City. But what was it really like? Prohibition In 1919, a new law in the US known as Prohibition made it illegal to buy and sell alcohol. But Prohibition didn't stop people drinking; it just drove the sale of strong alcoholic drink underground. Bootleggers waited off the coast of New York after dark and brought illegal alcohol into the city. Jazz Jazz was the music of New York in the 1920s. In fact, the decade is called Jazz Age. The best place to listen to this new form of music was the Cotton Club in Harlem. All the great jazz musicians played at the Cotton Club, including Louis Armstrong, Dizzy Gillespie and Duke Ellington. Also, in 1942 George Gershwin composed the jazz--influenced Rhapsody in Blue. The piece has been called "a musical portrait of New York" and was used by Woody Allen in his filmManhattan. Art Deco Art Deco was the most popular style of the 1920s, with bright colors and geometric designs; it can be seen in the art, architecture and inside designs of the period. New York is full of Art Deco buildings, but the most famous ones are the Chrysler Building (built between 1928 and 1930) and the Empire State Building (built between 1930 and 1931). The Great Depression On 29th October, 1929, the Roaring Twenties came to a dramatic end. On that day (known as "Black Tuesday"), the US stock market crashed, causing the Great Depression. The economic downturn lasted ten years and affected most of the Western world. Unemployment in America reached 25% and the country didn't recover until after World War II. Question: We know from the passage that in 1919 people _ alcohol in the US. - began to buy and sell - stopped producing - completely stopped trading - secretly bought and sold

Read the following article and select the best answer. Article: When a magazine for high school students asked its readers what life would be like in twenty years, they said: Machines would be run by solar power. Buildings would rotate so they could follow the sun to take maximum advantage of its light and heat. Walls would "give light" and "change color with the push of a button." Food would be replaced by pills. School would be taught by electrical impulse while we sleep. Cars would have radar . Does this sound like the year 2000? Actually, this article was written in 1958 and the question was, "what will life be like in 1978? The future is much too important to simply guess about, the way the high school students did, so experts are regularly asked to predict accuately. By carefully studying the present, skilled businessmen, scientists, and politicians are supposedly able to figure out in advance what will happen. But can they? One expert on Cities wrote: Cities of the future would not be crowded, but would have space for farms and fields. People would travel to work in "airbuses", large all-weather helicopters carrying up to 200 passengers. When a person left the airbus station he could drive a coin-operated car equipped with radar. The radar equipment of cars would make traffic accidents "almost unheard of". Does that sound familiar? If the expert had been accurate it would, because he was writing in 1957. His subject was "The city of 1982". If the professionals sometimes sound like high school students, it's probably because future study is still a new field. But economic forecasting, or predicting what the economy will do, has been around for a long time. It should be accuate, and generally it is. But there have been some big mistakes in the field, too. In early 1929, most forecasters saw an excellent future for the stock market. In October of that year, the stock market had its worst losses ever, ruining thousands of investors who had put their faith in financial foreseers. One forecaster knew that predictions about the future would always be subject to...

Ques: Read the following article and select the best answer. Article: The London Underground (The Tube) The main source of public transport in London revolves around the Underground (or the Tube as it is known to Londoners). This network of 12 lines can get you to most places in the center of the city quickly. It's most necessary to get an Oyster Card or a Travelcard. Single tickets are priced starting at the intentionally absurd price of PS 4.80 (Zone 1-3), if you pay cash. Using an Oyster card, a single fare is PS 2.30 if you are traveling within the central Zone 1. On hot days it is also advisable to take a bottle of water with you as Underground trains are not air-conditioned. Last trains leave central London at around 00:30 weekdays, 23:30 Sundays. First trains leave the suburbs at around 5:00. The Bus System Outside the center of London, Tube stations are farther apart, so buses help fill the gaps. Also, the bus offers a cheaper alternative, even if it is a slower journey. Cash fares for London buses have been abolished -- you cannot pay cash. A bus fare costs PS 1.50 if using only buses, the fare is capped at PS 4.40 per day for Oyster or contactless users. River Services There are a number of different routes along the River Thames. The faster commuter services operate all day from Greenwich Pier to Embankment and from Putney and Chelsea harbour to Blackfriars during Peak Hours only. These routes will pass a number of places of interest including the Houses of Parliament and London Bridge. A return fare from Putney to Blackfriars will cost about 12 pounds. National Rail Once you leave Central London or if you are traveling South of the River Thames, the best public transport option will often be National Rail. There are numerous connections to the Rail System from the Tube. Travelcards can be used for travel on the National Rail (but not the Heathrow Express). Oyster cards can be used up to Zone 6 except certain services including Heathrow Express, Heathrow Connect and HSI. Question: When taking the London Underground, _ . - you should buy tickets with cash - you can save more money with a single ticket - you can go to any place in London quickly - you are advised to take a bottle of water along on hot days

you are advised to take a bottle of water along on hot days
