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: A small, white envelope has peeked through the branches of our Christmas tree for the past 10 years. It has no name, no identification, no inscription . My husband Mike hated Christmas. He hated the overspending and the crazy running around at the last minute for the gifts given in desperation because you couldn't think of anything else. So one year I searched for something special to give Mike. The inspiration came in an unusual way. Our son Kevin was 12 and was on the school wrestling team. Shortly before Christmas, there was a non-league match against a team of poor kids. They were dressed in ragged sneakers, and presented a sharp contrast to our boys in their golden uniforms and sparkling new wrestling shoes. As the match began, I was alarmed to see that the other team was wrestling without helmets . Their team obviously could not afford them. We beat them hands down . Mike shook his head sadly. "I wish just one of them could have won," he said. Mike loved kids and enjoyed coaching football and baseball. That's when the idea for his present came. That afternoon, I went to a sports store and bought a load of wrestling headgear and shoes. I sent them anonymously to the poor team. On Christmas Eve, I placed a small, white envelope on the tree, the note inside telling Mike what I had done and that this was his gift from me. Mike's smile was the brightest thing about Christmas that year. In the years that followed, I sent a group of mentally handicapped youngsters to a hockey game, and a check to a pair of elderly brothers whose home had burned to the ground the week before Christmas. The white envelope became the highlight of Christmas. Mike died last year, but on Christmas Eve I still placed an envelope on the tree. The next morning it was joined by three more. Each of our three children had placed a white envelope on the tree for their dad. Mike's spirit, like the Christmas spirit, will always be with us. By Nancy W. Gavin

Question: Article: Without plant, people could not live. We eat plants. We breathe the oxygen that plants produce. And we need plants for another reason: we need them for their beauty. Imagine a world with no plants. Imagine no flowers with their sweet smells, their beautiful colors and their lovely shapes. Imagine when the wind blows, not being able to hear the leaves in the trees or watch the branches sway from side to side. Everywhere people need the beauty of plants. That is why we have parks full of trees and flowers. That is why people always try to design houses with room for some grass and a garden. Do you talk to your plants? Do you give them love and attention? Peter Tompkins and Christopher Bird, writers of a book called THE SECRET LIFE OF PLANTS, tell of an experiment in which two seeds were planted in different places. While the plants were growing, one plant was given love and hopeful ideas. The other plant was given only hopeless ideas. After six months, the loved plant was bigger. Under the earth it had more and longer roots; above the earth, it had a thicker stem and more leaves.
