[EX Q]: 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.
Answer: The workers didn't operate properly.
[EX A]: What is NOT one of the causes of this coal mine accident?

[EX Q]: Article: One in five American families will move every year. Moving is one of the most stress-producing events a family has to go through. Experts say it can be harder for children. How do you help your child adjust to the changes? The Ricardos moved from their old house to a new home. Same family, same dog-but it was harder for 9-year-old Elena. She hated the room, the house and everything. She hated leaving her friends the most. " I was so emotional. I mean, saying goodbye to all my friends.....my very close friends, who was my neighbor, made me so sad," says Elena. For some children, the emotional stress of moving is not much more different from the emotions when someone has died. "There's that sense that, 'I've lost my friends, my friends, my base, my school, my teachers-everything I knew that made me feel safe is all gone now. I have to start over," says Dr. Tim Jordan. Starting over is exactly Dr. Tim Jordan's advice. Make new friends, enter the new school and enter the new neighborhood. And here are some other pieces of advice. * Explain clearly to the children why the move is necessary. * Familiarize the children as much as possible with the new area with maps, photographs or the daily newspaper. * After the move, got the children to join in activities in the place. * Help the children keep in touch with friends from the neighborhood before through telephone, letters, e-mail, and personal visits.
Answer: Try letting children accept the fact of moving.
[EX A]: Which of the following is useful to reduce the children's stress before the move?

[EX Q]: Article: Food labels are such a mess that the government is redesigning them, as the ingredient lists are usually too confusing. As a result, a shopper could spend hours in a grocery store watching, calculating, and comparing, and still could not get it right. ShopWell is trying to help by allowing consumers to scan food labels and receive understandable and personalized information. Here's how it works. Register for ShopWell, and enter your age and gender. Add your goals (General health? Or are you trying to lose weight?). Then, note what you want in your diet, such as protein or iron, and what you want to avoid(added sugar, say). Add your allergies and things you cannot accept, and start scanning. Then ShopWell will come up with a clearly personal result: green for a food that is good for you; yellow for foods you can enjoy a little; and red for foods you should avoid. The results are easily understandable and is clean because it's not mixed with ads. Instead, ShopWell makes money by selling data to supermarkets. Its database contains 350,000 products, the app has been downloaded 1.3 million times, and the company claims a scan every two seconds "in stores such as Walmart, Whole Foods and 7-Eleven," in the words of marketing manager James Allgood. One of the first items I scanned was So Delicious Coconut Milk Creamer, which I buy because I'm lactose intolerant. It turns out it's only a little suitable for me -- because of its 1 gram per serving of added sugar. I'm not sure I'll give it up. But Ididask the app to watch for added sugar, and it's doing its job. One _ to ShopWell is that the scanner often doesn't work for items from Costco or Trader Joe's. Meanwhile, Some user reviews say that it doesn't cover enough allergies.
Answer: Because consumers can hardly make sense of the information on the food labels.
