Read the following passage and mark letter A, B, C or D on your answer sheet to indicate the word that best fits each of the numbered blanks. Unlike life in the countryside, which is often considered to be simple and traditional, life in cities is modern and complicated. People, from different regions, move to cities to seek a better life for them and their children. The inhabitants in cities work as secretaries, businessmen, teachers, government employees, factory workers and even street vendors or construction workers. The high cost of living requires city dwellers, especially those with low incomes, to work harder or to take part-time jobs. For many people, an ordinary day starts as usual by getting up in the early morning to do exercise in public parks, preparing for a full day of work and study, then travelling along boulevards or narrow streets filled with motorists and returning home after a busy day. They usually live in large houses, or high-rise apartment blocks or even in small rented rooms equipped with modern facilities, like the Internet, telephones, televisions, and so on. Industrialization and modernization as well as global integration have big impacts on the lifestyle in cities. The most noticeable impact is the Western style of clothing. The“Ao Dai” – Vietnamese women’s traditional dresses are no longer worn in their daily life. Instead, jeans, T-shirts and fashionable clothes are widely preferred. We can infer from the passage that ___________ A: people do morning exercise in public parks because they have much free time B: people leave the countryside because the life there is simple C: there is a big gap between the rich and the poor in cities D: most of the urban dwellers have low incomes
