Q: Read the following article and answer the question. Article: Seven species of carp  native to Asia have been introduced into United States waters in recent decades, but it's four in particular-bighead, black, grass and silver-that worry ecologists, biologists, fishers and policymakers alike. Introduced in the southeast to help control weeds and parasites in aquaculture   operations, these fish soon spread up the Mississippi River system where they have been crowding out native fish populations not used to competing with such aggressive invaders. The carps' presence in such numbers is also harming water quality and killing off sensitive species. Asian carp are strong to jump over barriers such as low dams. They lay hundreds of thousands of eggs at a time and spread into new habitat quickly and easily. Also, flooding has helped the fish expand into previously unattainable water bodies. And fishers using young carp as live bait have also helped the fish's spread, as they have boats going through locks up and down the Mississippi. The federal government considers the Asian carps to be annoying species and encourages and supports "active control" by natural resources management agencies. Federal and state governments have spent millions in tax dollars to prevent the carp from making their way into the Great Lakes, but an underwater electric fence constructed to keep them out has not worked as well as hoped, and policymakers are reviewing other options now. In the meantime, state and federal agencies are monitoring the Mississippi and its branches for Asian carp and testing various barrier technologies to prevent their further spread. For instance, the National Park Service is cooperating with the state of Minnesota's Department of Natural Resources to construct new dams that are high enough to prevent Asian carp from jumping over. The Asian Carp Regional Coordinating Committee has funded DNA monitoring in potentially affected water bodies whereby researchers can determine whether the troublesome fish are present just by the biological footprints they leave behind.... Question: The measure to keep Asian carp out of the Great Lake but proved not good is    _   . Answer:
Answer: construction of an underwater electric fence

Q: Read the following article and answer the question. Article: The uninvolved dad, turning up his nose at diapering  and too busy to bathe, dress and play with his kids,  is mostly a myth  , a big government survey suggests.  Most American fathers say they are heavily involved in hands-on parenting, the researchers found. The results are encouraging and important " because others have found the more involved dads  are, the better the outcomes for their children. " said researcher Jo Jones of the National Center for  Health Statistics, part of the Centers for Disease Control Prevention. She co-authored the report  released Friday. "Times have changed," said Robert Loftus, 34, of Yonkers, NY. He quit a six-figure sales  job a year ago to care for his two young children while his wife works full time. "We are trying to  rethink our priorities    and family seem to be N0 1  priority while in the past maybe people were more focused on career. " The study involved nearly 4.000 fathers who were interviewed in person between 2009 and 2013. *Key findings among fathers living with children younger than 5 : *9 in 10 bathed, diapered, helped them use the toilet or get dressed at least several times weekly . * Even higher numbers played with them and ate meals with them that often * Almost 2 0ut of 3 read to them at least several times weekly. *Among dads living with kids aged 5-18. * More than 9 0ut of 10 ate meals with them at least several times weekly and talked with them about what happened during the kids' day that often. * Almost 2 0ut of 3 helped with homework several times weekly. * About half took their kids to or from activities that often. Dr. David Hill, a Wilmington, N. C. pediatrician   said the survey reflects what he's seen among his patients'  fathers.  Increasingly, fathers rather than mothers take their kids to the doctor.  Some "are anxious about changing a diaper, "  he said. Census  numbers show that there were almost 190,000 stay-at-home dads nationwide last year versus 93,000 in 2010.  Loftus, the New York stay-at-home dad, said, "I feel fortunate to be able... Question: Which of the following can be the best title for the text? Answer:

Q: Read the following article and answer the question. Article: DU Lala is the hottest career coach in the country. The fictional character in the acclaimed novel Du La La's Promotion shows others how to take the high road to success in a multinational company. But does her story describe a real or distorted picture of work life? The answer is as complicated as office life itself. Over one million copies of the book have been sold since its release in 2007. Go Lala Go!, a movie adaptation of the novel set to hit cinemas next weekend, has stirred up even more interest in the story. The film stars Xu Jinglei and Stanley Huang, but fans seem to be more excited about seeing the story unfold on the big screen. According to a recent sina.com survey, 45 percent of the 6,810 netizens polled said they have drawn career pointers from the novel. Other office novels, such as In and Out of the Loop, Win and Lose and Drowning and Floating, seem to have been received with similar interest. "These books show me the life of white collars, and they teach me career rules and jargon that are not offered in class," said Zhang Shanshan, a 22-year-old senior at Beijing Forestry University. Zhang says the competition, humor and office gossip in the book intrigued her. "I can't wait to embark on my own career," she said. The popularity of office novels does not surprise Chen Ning, a senior career consultant at Zhaopin.com. "Novels about office fights and struggles satisfy the psychological demands of an ordinary office worker," Chen said. "The leading characters face great pressure, fierce competition and an uncertain future. This is what really happens in many readers' daily life."
