Question: Article: Many adults in the United States can remember crying the nursery rhyme in the street "Hot cross buns!" But only a few people realize this was an early form of advertising. Written advertisements probably began with hieroglyphics more than three thousand years ago, but only a few people could read these symbols. So merchants made signs with pictures or hung their tools over their doors to identify their businesses. In the time of the Roman Empire, wall paintings were a popular form of advertisement. An ad for a play, or some other performance was painted on part of a building or on a wall around a city. People often advertised a house for rent or a freshwater bath in this way, too. Today, large wall signs are still used for outdoor advertising. But outdoor advertising is only a small fraction of the total advertising. About forty per -cent of all ads are printed in daily newspapers. Radio commercials also provide this kind of information. Some people think they are the best form of advertising because radio broadcasts reach almost everyone in a nation. Advertisements in magazines and on television reach many people, too. However, usually only large companies can advertise on a national network, because TV commercials shown across the country can cost many thousands of dollars. Then there are ads that are almost part of daily living. If you use public transportation, you will see large printed ads, called ear cards, on buses and taxis and in trains. Ads are painted on the trucks that deliver products people are buying or selling.
Question: Which is the passage mainly discussing?
Options: (A) Modern advertising (B) Significance of advertising (C) Development of advertising (D) Origin of advertising

Answer: C

Question: Article: School uniforms are becoming more and more popular across the U.S.A. That's no surprise,because they offer many benefits. They immediately end the powerful social sorting and labeling that come from clothing. If all students are dressed in the same way,they will not pay too much attention to their clothing,and some of them will not be laughed at for wearing the "wrong" clothes. Some people are against the strict rule of school uniforms,but they do not realize that students already accept a kind of rule -- wanting to look just like their friends. The difference is that the clothing students choose for themselves creates social barriers ; school uniforms tear those barriers down. As in other places,uniforms remind the wearers of their purposes and duties. For example,when a man or woman puts on a police uniform,he or she becomes,for a time,the symbol of law and order. The uniform means to the wearer his or her special duties and sends the same message to everyone the wearer meets. People with different jobs wear uniforms of one kind or another. For students,the school uniform reminds them that their task for the six or seven hours they are in school is to get an education. Some parents are unhappy about uniforms,saying that school uniforms will affect their children's "creativity". First,as noted above,the clothes students choose to wear do not necessarily express their individuality . They just copy their classmates. Second,students have the rest of the day to be as creative as they like. While they're in school,their job is to master reading,writing,and maths; this should take up all the creativity they have. Mastery of those skills will be good for the students to build up their creativity in every way.

Options: (A) prevent the wearers from being laughed at (B) help the wearers keep their duties in mind (C) are seen as a symbol of power (D) help to create social barriers

Answer:
B
