PROBLEM: Article: Ask a teacher to name the most annoying invention of recent years and they will often mention the mobile phone. Disturbed by the problems they create, many head teachers have ordered that pupils should keep their phones switched off at school. Others have told pupils to leave them at home. However, education researchers at The University of Nottingham believe it is time that phone bans were reassessed, because mobile phones can be a powerful learning aid, they say. Dr Elizabeth Hartnell-Young and her colleagues have reached this conclusion after studying the consequences of allowing pupils in five secondary schools to use either their own mobile phones or the new generation of 'smartphones' in lessons. During the nine-month experiment, 14- to-16-year-old pupils used the phones for a wide range of educational purposes, including creating short movies, setting homework reminders, recording a teacher reading a poem, and timing experiments with the phones' stopwatches. The smartphones, which could be connected to the Internet, also allowed pupils to access revision websites, log into the school email system, or transfer electronic files between school and home. The research involved 331 pupils in schools in Cambridgeshire, West Berkshire and Nottingham. "At the start of the study, even pupils were often surprised at the thought that mobile phones could be used for learning," Dr Hartnell-Young said. "After their hands-on experience, almost all pupils said they had enjoyed the project and felt more inspired." Some teachers found that pupils who lacked confidence gained most from the project. However, they recognized that greater use of mobile phones in schools could cause problems.
Question: When the students first used mobile phones for learning, they _ .
Options: (A) all enjoyed the project very much (B) didn't know what they were used for (C) didn't fully realize the learning functions of mobile phones (D) were surprised that they were allowed to use mobile phones in schools
Asnwer: C

SOLUTION: Yes

PROBLEM: Article: The U. S. Postal Service (USPS) is losing billions of dollars a year. The government company that delivers "small mail" is losing out to email and other types of electronic communication. First-class mail amount fell from a high point of 104 million pieces in 2000 to just 64 million pieces by 2014. Congress permits the 600.000-empIoyee USPS to hold a monopoly over first-class and standard mail. The company pays no federal, state or local taxes; pays no vehicle fees; and is free from many regulations on other businesses. Despite these advantages, the USPS has lost $52 billion since 2007, and will continue losing money without major reforms. The problem is that Congress is preventing the USPS from reducing costs as its sales decline, and is blocking efforts to end Saturday service and close unneeded post office locations. USPS also has a costly union-dominated workforce that slows the introduction of new ideas or methods down. USPS workers earn significantly higher payment than comparable private-sector workers. The answer is to privatize the USPS and open postal markets to competition. With the rise of the Internet, the argument that mail is a natural monopoly that needs government protection is weaker than ever. Other countries facing declining letter amounts have made reforms Germany and the Netherlands privatized their national postal companies over a decade ago, and other European countries have followed suit. Britain floated shares of the Royal Mail on its stock exchange in 2013. Some countries, such us Sweden and New Zealand, have not privatized their national postal companies, but they have opened them up to competition. These reforms have driven efficiency improvements in all of these countries. Additional number of workers have been reduced, productivity has risen and consumers have benefited. Also, note that cost-cutting measures--such as closing tone post offices--are good for both the economy and the environment. Privatization and competition also encourage new changes. When the USPS monopoly over "extremely urgent" mail was stopped in 1979, we saw an explosion in efficient overnight private delivery by firms such as FedEx. The government needs to wake up to changing technology, study postal reforms abroad and let businessmen reinvent our out-of-date postal system.
Question: What do we know about the USPS?
Options: (A) Its great competitor is the delivery firm FedEx. (B) It is an old public service open to competitions. (C) Its employees don't pay federal, state or local taxes. (D) It has complete control of first-class and standard mail.
Asnwer: A

SOLUTION: No

PROBLEM: Article: Street art can be found on buildings, sidewalks, street signs and even trash cans from Tokyo to Paris to New York City. This special kind of art can take the form of paintings, sculptures, cloth or even stickers. Street art has become part of a global visual culture. Now, even art museums and galleries are collecting the work of street artists. It is not easy to provide an exact history of the street art movement. This kind of art has developed in many kinds of ways in places all over the world. Also, because it is illegal to paint public and private property without permission, street artists usually work secretly. This secretive nature of street art and its countless forms make it hard to define exactly. And people have different opinions about the movement. Some think street art is a crime and destroys property. But others see this art as a rich form of non-traditional cultural expression. Many experts say the movement began in New York City in the nineteen sixties. Young adults would use paint in special cans to spray their TAG on walls and train cars around the city. This tag was a name they created to identify themselves and their artwork. This colorful style of writing is also called graffiti. It is visually exciting and energetic. Graffiti also became a separate movement expressing the street culture of young people living in big cities. Graffiti art represented social and political rebellion. These artists could travel around areas of the city making creative paintings for everyone to see. Sometimes this street art created a dispute between artists and city officials. Graffiti artists created their images and city officials quickly painted over them. During the 1980s, two famous New York painters--Keith Haring and Jean Michel began showing their work in art galleries and museums. This is when street art started to become part of the more general popular culture.
