People do not analyze every problem they meet. Sometimes they try to remember a solution from the last time they had a similar problem. They often accept the opinions or ideas of other people. Other times they begin to act without thinking. They try to find a solution by trial and error. However, when all these methods fail, the person with a problem has to start analyzing. There are six stages in analyzing a problem. First the person must recognize that there is a problem. For example, Sam's bicycle is broken, and he cannot read it to class as he usually does. Sam must see that there is a problem with his bicycle. Next the thinker must define the problem. Before Sam can repair his bicycle, he must find out the reason why it does not work. For instance, he must determine if the problem is with the gears, the brakes, or the frame. He must make his problem more specific. Now the person must look for information that will make the problem clearer and lead to possible solutions. For instance, suppose Sam decided that his bike does not work because there is something wrong with the gear wheels. At this time, he can look in his bicycle repair book and read about gears. He can talk to his friends at the bike shop. He can look at his gears carefully. After studying the problem, the person should have several suggestions for a possible solution. Take Sam as an illustration. His suggestions might be: put oil on the gear wheels; buy new gear wheels and replace the old ones; tighten or loosen the gear wheels. Eventually one suggestion seems to be the solution to the problem. Sometimes the final idea comes very suddenly because the thinker suddenly sees something new or sees something in a new way. Sam, for example, suddenly sees that there is a piece of chewing gum between the gear wheels. He immediately realizes the solution to his problem: he must clean the gear wheels. Finally the solution is tested. Sam cleans the gear wheels and finds that afterwards his bicycle works perfectly. he has solved the problem. By referring to Sam's broken bicycle, the author intends to    _   . A) illustrate the ways to repair his bicycle B) discuss the problems of his bicycle C) tell us how to solve a problem D) show us how to analyze a problem

(Question)
With hospitals and nursing homes tending to thousands of patients every year accidents can---and do ---happen. These incidents whether they are through carelessness or otherwise, can leave patients feeling powerless. That's not the case.    "There is growing public awareness. People are feeling they have more rights and they have tools in hand to make a complaint," said Ralph Montano, spokesman for the California Department of Public Health, which regulates hospitals and long term care facilities in the state.     That department received more than 6000 complaints about hospitals in 2007; in the most recent year statistics are available. The complaints can be about mixed-up lab results, medicine errors, foreign objects left in a patient during surgery or a host of other topic.     Similarly, the California Department of Aging received 43000 nursing home complaints in 2009. Some said patient abuse or neglect of patients; others reported missing items. And some commented on the quality of the food.      But finding the channels through them to put forward a complaint can be tiring and time consumption. Many consumers simply don't bother, and some become lost in the system. Whether the complaint is against a hospital or a long-term care facility, the process is similar--- and many people can help, including the facility's staff, insurance company representatives and state regulators.     If you want to make a complaint while in the hospital, Patti Harvey, vice president of quality and patient care services for Kaiser Permanente in Southern California, recommends talking with the bedside nurse. If that doesn't work, you can talk with other people higher in the chain of command, up to the hospital administrator. If the problem isn't still taken care of ---say you disagree with your treatment plan or have a problem with your doctor---member service offices at each hospital can help address your concerns. Why are there more complaints from patients? A) Because hospitals have more and more rights. B) Because it's convenient for people to put forward complaints. C) Because in the hospital there are more accidents than before. D) Because there are more departments to deal with complaints.

Question: Ever wonder why sometimes a hug is all you need ? You can't explain it , but there's just something comforting about being in your wife's arms after a rough day or giving mom a hug after a long time apart . A new study says the warm feeling in a hug is more than just skin deep . Researchers from the University of California , Berkeley believe that this loving feeling could have anti-aging benefits . Oxytocin , sometimes referred to as the " love hormone " or the " trust hormone , " is responsible for those indescribable feelings we get when we're bonding with a lover or a loved one . Levels of the hormone drop as we age , and evidence suggests that could be a contributing factor to the _ of our bodies as we age . Muscle loss in particular is one of the major side effects of aging , with our bodies losing up to 5 percent of our muscle mass each decade past our 30s . In the study , published in the journal Nature Communications , researchers injected oxytocin into older mice with muscle damage . The older mice had lower levels of the homeone than younger mice initially . But after nine days , the older mice who were given the hormone healed better than those who did not . In fact , their ability to repair muscle damage was up to 80 percent that of the younger mice . The results were not only fast-acting , but provide hope for future uses of the hormone in a variety of anti-aging capacities . " This is good because it demonstrates that extra oxytocin improves aged tissue stem cells without making muscle stem cells divide uncontrollably , " study co-author Wendy Cousins said in a statement . Previous uses of anti-aging molecules have also been associated with higher cancer risk , but researchers are hopeful that oxytocin can be useful in humans without this risk . In the future , researchers of Berkeley say oxytocin could be used to fight other age-related health issues by improving bone health and even being used as an alternative to hormone replacement therapy . Now go out and give someone a hug . What can be learned from the research ? A) All the older mice healed faster in the research . B) Older mice healed better than younger ones after 9 days . C) Extra oxytocin in older mice controlled muscle cell division . D) Mice with oxytocin injection improved the ability to repair muscle damage .
