In this century the traditional American family is constantly faced with the threat of breakdown. Some people suggest that one little - noticed cause may be the introduction of the TV dinner. Before the appearance of television seats, the American dinner was a big event for the family. In many homes dinner time may be the only time when everyone got together. A typical dinner was usually in three periods In the preparation period, the children and Father frequently helped with setting while Mother put the last touches on the roast. In the eating period, family members shared the day's experiences and more than food was eaten. In this period,families got to know one another and made joint decisions around the dinner table, and thus the family solidarity was strengthened. In the cleaning - up period,children or Father again gave their hands, so that their meaning to the home community was clear. Unfortunately, all of these have been abandoned by a product--the television set. By the beginning of the 1980s, the typical American family dinner was just twenty minutes long. The speed - up of this once - leisurely experiences is clearly connected to the overall pace of modern life and maybe a model of the modern life is the TV dinners--meals designed to be used between the opening and closing credits of a half - hour program. The once family affair has now become nothing more than the use of a fork and knife. The shortening of the dinner time in America is related to_. A) the TV programs B) the pace of modern life C) the wide use of household appliances D) the popularity of fast food

Q: 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... We can learn from the text that _ . A) Faulds collected many fingerprints while in Japan B) Henry's classification system is based on Gallon's C) Darwin showed great interest in studying fingerprints D) Vucetich's fingerprinting system is still used all over the world
