Problem:OPTIONS:
- it was easier and cheaper to receive information by radio
- nobody supported the development of the newspaper industry
- newspapers were not a primary information provider any longer
- many people were too poor to buy newspapers in the early 20th century

Read the following article and answer the question. Article: By the middle of the 19th century, newspapers were becoming the primary means of spreading and receiving information. The period between 1890 and 1920 is known as the "golden age" of print media. Broadcast radio came onto the media scene in the 1920's. Newspapers were forced to re-evaluate their role as society's primary information provider. Like the new media technologies of today, the development of a low-cost, convenient media source produced results that radio would greatly affect the newspaper industry. No sooner had newspapers adapted to radio than they were forced to re-evaluate themselves because of a new and more powerful medium: television. Between 1940 and 1990, newspaper sales in America dropped from one newspaper for every two adults to one for every three adults. Some newspapers, like USA Today, responded to the technological advancements by using color1 and the "short, quick and to the point" stories that are usually featured on television. The technological revolution of today is creating new challenges and opportunities for traditional media. Never before has so much information been so accessible to so many. By the end of the 1990s, about 700 traditional media had websites; today there are thousands. The amount and speed of information on the Internet is _ , but it has not signalled the end of the newspaper's existence . Newspapers in print remain a popular and powerful medium for the reporting and analysis of events that shape our lives. It is reported that one billion people in the world read a newspaper every day! Question: Radio had a great influence on the newspaper industry because _ . Answer:
****
A: it was easier and cheaper to receive information by radio

Problem:OPTIONS:
- Rescued miners speak out
- Miners' life deep underground
- A rebirth for 33 rescued miners in Chile
- Chilean president honors rescued miners

Read the following article and answer the question. Article: IQUIQUE, Chile (Reuters) -- Rescue workers at the San Jose gold and copper mine in northern Chile had reason to sing this week. A small hole drilled into the earth became a passage to freedom for 33 trapped miners, who spent 69 days underground. "Never have people been trapped for so long so deeply," says a doctor at NASA, the American space agency, which helped in the rescue. But the chief medical officer for the miners said most are in good enough health to leave the hospital within a day or so. The first three recovered and went home Thursday night. For much of the day the miners relaxed with Chilean President Sebastian Pinera. The 32 Chileans and 1 Bolivian still wore special sunglasses to protect their eyes. A partial mine collapse on 5th August trapped them more than half a kilometer underground. They had to stretch a two-day food supply. For two weeks no one knew if they were alive or dead. Later, they received supplies. The first miner rescued on Wednesday was Florencio Avalos. The second was Mario Sepulveda, who talked about how the experience tested his faith. The last miner up was Luis Urzua, who was the shift leader when his crew became trapped. Rescuers used a metal cage to pull the miners to safety in less than 24 hours -- faster than expected. The rescue capsule was a half-meter wide and known as the Phoenix, an imaginary bird from ancient stories. It bursts into flames but is continually reborn and rises from the ashes. Chile's Navy built the capsule with advice from mining experts and NASA engineers. It worked like an elevator, traveling up and down on a cable through a shaft drilled 622 meters into the rocks. Millions of people around the world watched the rescue. More than one thousand journalists traveled to the mine in the Atacama Desert to report on the rescue. They joined family members of the miners and rescue crews housed in an area of tents known as Camp Hope. Question: What would be the best title for the passage? Answer:
****
A: A rebirth for 33 rescued miners in Chile

Problem:OPTIONS:
- Because it can't be heard by human ears.
- Because it can only be heard by female elephants.
- Because people don't know its meanings.
- Because people haven't studied it completely.

Read the following article and answer the question. Article: Researchers at San Diego Zoo have been studying what has been described as the "secret language" of elephants. They have been monitoring communications between animals that cannot be heard by human ears. The elephant's call will be familiar to most people, but the animals also give out growls . Their growls, however, are only partly audible ; two-thirds of the call is at frequencies that are too low to be picked up by our hearing. To learn more about the inaudible part of the growl, the team attached (......) a microphone sensitive to these low frequencies and a GPS tracking system to eight of the zoo's female elephants. The researchers could then relate the noises the animals were making to what they were doing. Matt Anderson, who led the project, told BBC News, "We're excited to learn how they interact and contact with one another." The team has already learned that pregnant females use this low frequency communication to announce to the rest of their long gestation of over two years, in the last 12 days we see the low part of the growl, which we can't hear. This we believe is to announce to the rest of the herd that the baby is upcoming," said Dr Anderson. The researchers believe that this also warns the elephants to look out for coming danger. "You may think that a baby calf of about 300 pounds would not be as open to predation as other species," he says. "But packs of hyenas are a big threat in the wild." Female elephants are only in season for around four days every four years and these calls can be heard by males more than two miles away. Question: Why some elephants' call is called "secret language"? Answer:
****
A:
Because it can't be heard by human ears.
