question:
Article: I come to the United States ten year ago. I would always say that I was trying to study, but there were always things like work and my kids that would not allow me to start. Now I realized that those were only excuses. What stopped me was that I was afraid to start studying again. I always believed I would learn by myself. One day, however, my son told me that he was sad because his friends would come over and I didn't understand them because I didn't speak English. He was also sad because I could never help him with his homework. That same day, I told myself, "Rocio, you have to start believing in yourself and you will see you can make it." The next day, I went downtown to look for a big banner   in front of the school which said that they offered classes for adults. I came in to see if I could join, but the classes were closed  already. That night I took the kids to the movies, and on the way back, I told them we would take a new route. I ended up getting lost. That's the way I found Chaffey College. The following Monday, I went to ask for information. They told me that summer school was starting that week. That's how I started studying English last summer. It is difficult, but I have had great rewards. My daughter had to write a story for school. It was about the female they most admired and why . She wrote that I was the person she most admired because I had started going to College. I will never forget this.

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: You may have heard the popular saying, "there are always more fish in the sea". But as many new studies show, fish populations are changing, and not necessarily for the better. Consider the case of big, predatory   fish. These giants, like sharks and cod  , eat other smaller fish. Big fish are an important part of the marine ecosystem   because they keep down the numbers of smaller fish. Without fish that eat other fish, populations of smaller swimmers would increase, eating more plants, and leaving less vegetation for other creatures, including future fish. As fierce as predators can be, they're no match for fishing technology. Many people love to catch predatory fish like sharks, cod and tuna, and new studies suggest that over-fishing is threatening these creatures near the top of the marine food chain. In one study, Villy Christensen and his colleagues looked at 200 past studies of marine life to learn how fish populations have changed over time. Christensen reported that between 1910 and 1970, the numbers of big predators decreased slowly, and that in 1970 their populations really started to drop. Around that time, fishing ships began using new tools that led to more fish being caught. The numbers have been falling quickly ever since. Reg Watson looked at the problem from the perspective of the fishermen. In the middle of the 20thcentury, Watson reported, fishing boats didn't go far from home, and most fish were caught near the shore. That was no longer true by the 1980s. By then, fishing had moved farther from shore, into the open oceans, and was helped by the development of new technologies. But since the 1990s, something has changed. Despite new technologies and more efforts, fishing operations have not continued to develop. Scientists study historical data to understand the present, and this research is needed to forecast the future of fish and fishing. And the forecast doesn't look good: large predator fish are becoming harder to find, and soon may disappear. 
 Question: Why did the number of big predators begin to fall quickly in 1970? 
 Options: (A) Fishing ships began using new tools with which they could catch more fish. (B) There were fewer smaller fish than before. (C) There were more people catching big predators. (D) Their environment was being polluted by fishing ships.
answer:

A
