Article: Just seven years ago, the Jarvik-7 artificial heart was being cheered as the model of human creativeness. The sight of Barney Clark----alive and conscious after trading his diseased heart for a metal-and-plastic pump----convinced the press, the public and many doctors that the future had arrived. It hadn't. After monitoring production of the Jarvik-7, and reviewing its effects on the 150 or so patients (most of whom got the device as a temporary measure) the U.S. Food and Drug Administration concluded that the machine was doing more to endanger lives than to save them. Last week the agency cancelled its earlier approval, effectively banning the device. The recall may hurt Symbion Inc., maker of the Jarvik-7, but it won't end the request for an artificial heart. One problem with the banned mode is that the tubes connecting it to an external power source created a passage for infection. Inventors are now working on new devices that would be fully placed, along with a tiny power pack, in the patient's chest. The first sample products aren't expected for another 10 or 20 years. But some people are already worrying that they'll work---and that America's overextended health-care programs will lose a precious $2.5 billion to $5 billion a year providing _ for a ly few dying patients. If such expenditures cut into funding for more basic care, the net effect could actually be a decline in the nation's health. Question: From the passage we know that Symbion Inc. _ . Yes or no, is the answer "may continue to work on new models of reliable artificial hearts"?
No

Article: In the digital age, getting students into classrooms is an increasingly challenging mission for college and university teachers, not to mention retaining their attention. "It's much harder to teach the post-90s,,,said Chen Jixiu , a math professor at Fudan University. "They use smart-phones and tablets to search for information, even during class. They get knowledge from a variety of sources, and consider it 'a small cake ,to skip classes. " According to Chen, this situation has forced teachers to adopt "odd tricks" for attracting students to class. Here are some interesting ideas picked up by 21st Century. Food for Thought: Rather than providing only moral encouragement, teachers at Wuhan University are offering real-life related rewards to improve student attendance. Students sitting in the first row of the health psychology course taught by professor Lei Wuming are rewarded with snacks. "I've got 7,000 fans on my micro-blog ,and most of them are my students,"said Lei ,director of the university's Education Institution. "I do want to express my thanks to those coming to listen, and to make the class more lively. " Teacher vs Phone; In the broadcasting and hosting course of Hankou University, teacher Huang Huiqiong gives students permission to busy themselves with their cell phones during class. They keep their heads down until they hear something interesting. If not, they can sit through the entire class without being disturbed and even give the teacher advice following the class. "A teacher is not the boss and students have the right to make content suggestions,,,said Huang. Friendly Blogs: You might hesitate to participate in class discussions, but what if you could send a message instead of speaking out loud? In the computer science course at Changsha University of Science Technology (CUST),students can voice opinions via their cell phone. "I open a micro-blog webpage,and when students text a message to the account, it appears on the screen,,,said teacher Huang Qiang. Su Ying, 19,a sophomore at CUST,... Question: How does Lei Wuming improve his students' attendance? Yes or no, is the answer "He offers some food as rewards."?

Article: Computers have beaten human world champions at chess and, earlier this year, the board game Go. So far, though, they have struggled at the card table. So we challenged one AI to a game. Why is poker so difficult? Chess and Go are "information complete" games where all players can see all the relevant information. In poker, other players' cards are hidden, making it an "information incomplete" game. Players have to guess opponents' hands from their actions--tricky for computers. Poker has become a new benchmark for AI research. Solving poker could lead to many breakthroughs, from cyber security to driverless cars. Scientists believe it is only a matter of time before AI once again _ humans, hence our human-machine match comes up in a game of Texas Hold's Em Limit Poker. The AI was developed by Johannes Heinrich, researcher studying machine learning at UCL. It combines two techniques: neural networks and reinforcement learning . Neural networks, to some degree, copy the structure of human brains: their processors are highly interconnected and work at the same time to solve problems. They are good at spotting patterns in huge amounts of data. Reinforcement learning is when a machine, given a task, carries it out, learning from mistakes it makes. In this case, it means playing poker against itself billions of times to get better. Mr Heinrich told Sky News: "Today we are presenting a new procedure that has learned in a different way, more similar to how humans learn. In particular, it is able to learn abstract patterns, represented by its neural network, which allow it to deal with new and unseen situations." After two hours of quite defensive play, from the computer at least, we called it a draw. Question: Why can't the computer beat humans at the poker game? Yes or no, is the answer "Because the computer can't know the other players' cards completely."?
No
