Q: I'm taking a test and have to guess the right answer to the question after the article. Article: BEIJING -- The rescue operations at a coal mine accident have ended with 105 miners dead. The State Council has organized an investigation team to probe into what caused the disaster in the city of Linfen, North China's Shanxi Province. Preliminary investigations show the illegal mining of an unauthorized seam , and the number of miners who had been sent down the shaft far exceeded its capacity. This mine was found to have long ignored the rules to steal state coal, and did not have a list of miners employed to check the number of miners missing after the accident. How did such a coal mine get all the necessary licenses for production? How did it pass the three safety inspections the local government organized last month? In response to this disaster, the Shanxi governor promised to set up hotlines for people to report illegal coal mines and rewards as high as 100,000 yuan for _ We appreciate the action this governor has taken to solving the coal mining problems, and we believe that the reporting scheme will help to stop the existence of illegal coal mines. But at the same time we have reason to question how governments at various levels supervise these mines. The sad fact that such a mine with serious safety problems could pass three consecutive local government safety inspections in a month is enough to tell us how ineffective the safety inspections were. What if these inspections were just a formality ? What if the inspectors were bribed by the mine owners to turn a blind eye to the safety dangers? We can well imagine what would happen if reports about mine problems were handled by such officials. So a thorough probe must find out who are responsible for the death of so many miners. A real safety inspection and management system must be established to guarantee that safety dangers will be removed. Question: What is NOT one of the causes of this coal mine accident? Options: A: The workers didn't operate properly. B: The mine didn't obey the rules to mine for coal. C: A lot more miners than allowed were working under the mine. D: The safety inspections were ineffective.

Q: I'm taking a test and have to guess the right answer to the question after the article. Article: What Is Self-tracking All about Have you ever monitored something about yourself? Perhaps you've tracked how many kilometers you've run, how many hours you've slept or how many calories you've eaten in a day. If so, you've taken part in a movement called the "Quantified Self Movement." Individuals gather information about their daily activities in this popular movement, also called self-tracking. This may sound difficult, but technology is making the process easier. Perhaps you've wanted to change a bad habit but couldn't. Self-tracking may be your answer. The idea is to take information about your everyday activities and analyze them to help form a healthier lifestyle. Recently, tools such as smartphones, journals and apps, along with newly published wearable things, are making self-tracking extremely easy. Today, one can use Fitbit, the Jawbone Up, Google Glass or a smart watch to record personal data including sleeping hours, stress levels, heart rate and mood. So why does a person self-track? Someone may be trying to lose weight or improve their sleep patterns. Another person feels tired after eating. Self-tracking could help him to know what foods make him sleepy and watch his diet. Monitoring daily activities isn't a new concept. In years past, athletes and their coaches kept notes detailing nutrition, training and sleep patterns in order to achieve an athletic goal. Similarly, doctors have also helped patients to record parts of their lifestyles and eating habits to help fight allergies, headaches and other health problems. However, it wasn't until 2007 that magazine editors Gary Wolf and Kim Kelly, who started tracking every move they made, coined the term "Quantified Self." Wolf says that the new tools will change our sense of self with the purpose of making us more effective in the world. Although self-tracking has many advantages, Dennis Nash, president of Data Speaks Health Solutions, says self-tracking has its drawbacks. Once people start tracking their daily activities, it can become an addition... Question: People choose self-tracking because _ . Options: A: it collects personal data and leads to self-improvements B: it records how many hours you sleep a day C: it watches your eating habits D: it increases your movement

Q: I'm taking a test and have to guess the right answer to the question after the article. Article: HARTLAND, Wis. (AP) -- Lauren Panos was surprised when she walked into her ninth-grade English class in the fall and saw there were no boys. Her parents had not told her they had enrolled her in a new all-girls class at Arrowhead High School in Hartland. Panos still isn't sold on the idea. "All the girls there, they can talk out of turn," the 14-year-old said. "We are bored of tasks and it's really upsetting." More public school systems are looking at separating boys and girls, whether for certain classes or by total schools, after the federal government opened the door last fall. Supporters say separating students by sex helps them learn better and allows boys and girls to explore subjects they may not otherwise take. "Boys just make a bigger trouble in the class," Panos' classmate, Alyson Douglas, 15, said "I likes not worrying about boys causing _ ." Presently, nationwide, at least 253 public schools offer single-sex classes and 51 schools are entirely single sex, according to the National Association for Single Sex Public Education. In1995, just three public schools offered single-sex classes. Critics of same-sex classrooms argue that proven methods of improving education should be carried out instead of one that divides boys and girls. "Too many schools feel they can carry out a social experiment with students' education with really the weakest of theories," said Emily Martin, deputy director of the American Civil Liberties Union's Women's Rights Project. Single-sex schools are an "illusionary silver bullet," said Lisa Maatz, director of public policy and government relations for the American Association of University Women. They distract from real problems and do not offer proven solutions such as lower class sizes and enough funding, she said. "I would suggest that for many of our kids and families, especially in Milwaukee, it's a question of choice," Spence said. "We have a series of choices in Milwaukee and I just think this should be one additional choice." Question: Critics don't support the idea of single-sex schooling mainly because _ . Options: A: boys will cause more trouble and girls will hate studying. B: single-sex schooling that is not a proven idea can leave out key problems C: it doesn't help students develop fully and healthily D: it can excite students to explore the unknown
A: B
