Article: Rock stars and their money Around the world young people are spending unbelievable sums of money listening to rock music.

Luck is a key word for explaining the success of many. In 1972 one of the luckiest was Kon Mclean, who wrote and sang "American Pie".

Article: There are records of fingerprints taken many centuries ago. The ancient Babylonians pressed the tips of their fingerprints into clay to record business trade. The Chinese used ink-on-paper finger impressions for business. However, fingerprinting wasn't used as a method for identifying criminals until the 19th century. In 1858, Sir William Herschel was working as an official of the Hooghly district in Jungipoor, India.In order to reduce fraud , he had people living in the district record their fingerprints when signing business documents. A few years later, Scottish doctor Henry Faulds was working in Japan when he discovered fingerprints left by artists on ancient pieces of clay.This finding inspired him to begin investigating fingerprints.In 1880, Faulds wrote to his cousin, the famous naturalist Charles Darwin, and asked for help with developing a fingerprint classification system.Darwin refused, but sent the letter to his cousin, Sir Francis Gallon, who was an eugenicist . Gallon began collecting fingerprints and eventually gathered some 8, 000 different samples to analyze. In 1892, he published a book called "Fingerprints", in which he outlined a fingerprint classification system--the first existence. Around the same time, Juan Vucetich, a police officer in Buenos Aires, Argentina, was developing his own version of a fingerprinting system.In 1892, Vucetich was called in to assist with the investigation of the two boys murdered in Necoche, a village near Buenos Aires. Their mother, Francisca Rojas, accused a neighbour named Velasquez. But when Vucetich compared the fingerprints found at the murder scene to those of both Velasquez and Rojas, _ matched Rojas' exactly.She admitted her crime. This was the first time fingerprints had been used in a criminal investigation.Vucetich called his system comparative dactyloscopy . It's still used in many Spanish-speaking countries. Sir Edward Henry, in charge of the Metropolitan Police of London, soon became interested in using fingerprints to catch criminals. In... Question: What is the text mainly about? Yes or no, is the answer "The history of fingerprinting."?

Q: Article: Two new whale sharks arrived at the world's largest aquarium on Friday. Both whale sharks, the world's largest fish, arrived at the Georgia Aquarium in Atlanta after 6 a.m. The pair had been flown 8,000 miles from Taipei, Taiwan. They will join the aquarium's three whale sharks--the only ones on display outside of Asia. " We re the only people in the world that can claim three times, " aquarium director Jeff Swanagan said, " Each time we learn more and more." The two young males were given Asian names. One is Taroko, named after Taroko Gorge, a national park in Taiwan. The other is Yushan, which means "Jade Mountain", and is named after a mountain in Taiwan. The sharks were flown from Taiwan on a plane in 20-foot-long tanks with oxygen machines and other equipment to keep the water suitable for them. They arrived at about 3:30 a.m. in Atlanta, where their tanks were moved to two trucks and driven to the aquarium surrounded by some of Atlanta police cars with their blue lights flashing. They were lowered into their new home--as Norton and two females, Alice and Trixie, circled nearby, seemingly curious about the new arrivals. It is difficult to tell the age of the whale sharks, but at least one of the new arrivals is believed to be the smallest the aquarium has got. They are believed to be the aquarium's youngest whale sharks yet. Question: How many sharks live with the two new sharks? Yes or no, is the answer "Three."?
A: Yes

*Question*
Article: About six years ago I was eating lunch in a restaurant in New York City when a woman and a young boy sat down at the next table. I couldn't help overhearing parts of their conversation. At one point the woman asked: "So, how have you been?" And the boy--who could not have been more than seven or eight years old--replied, "Frankly, I've been feeling a little depressed lately." This incident stuck in my mind because it confirmed my growing belief that children are changing. As far as I can remember, my friends and I didn't find out we were "depressed", that is, in low sprits, until we were in high school. Undoubtedly a change in children has increased steadily in recent years. Children don't seem childlike anymore. Children speak more like adults, dress more like adults and behave more like adults than they used to. Whether this is good or bad is difficult to say, but it certainly is different. Childhood as it once was no longer exists. Why? Human development is based not only on born biological states, but also on patterns of access to social knowledge. Movement from one social role to another usually involves learning the secrets of the new status. Children have always been taught adult secrets, but slowly and in stages: traditionally, we tell sixth graders things we keep hidden from fifth graders. In the last 30 years, however, a secret-revelation machine has been installed in 98 percent of American homes. It is called television. Television passes information to all viewers alike, whether they are children or adults. Unable to resist the temptation, many children turn their attention from printed texts to the less challenging, more vivid moving pictures. Communication through print, as a matter of fact, allows for a great deal of control over the social information to which children have access. Reading and writing involve a complex code of symbols that must be memorized and practiced. Children must read simple books before they can read complex materials. Question: What does the author think of communication through print for children? Yes or no, is the answer "It can control what children are to learn."?
**Answer**
No
