Outside our hotel in Ho Chi Minh City, Vietnam, a seemingly ancient woman waited beside the door with her hand outstretched. Every day I put my hand in hers as our eyes met. She never failed to return my smile, my grasp, and my greeting. On the last day of our visit, I found myself alone on a busy corner across the street from our hotel. Bicycles and motorbikes rushed in front of me. As I hesitated on the sidewalk, I felt a hand on my elbow and looked down to see the smile of my small beggar friend looking up at me. She nodded her head toward the street, indicating that she would take me across. Together, we moved slowly into the chaos. Then we moved on toward the sidewalk, where she pulled my face down to hers, kissed me on both cheeks, and then left, still smiling and waving back to me. Traveling in poorer nations, I have witnessed a variety of ways to deal with beggars. The most common response of tourists faced with the poverty-stricken is to ignore them and focus their eyes elsewhere. I have seen people push away an outstretched hand in angry annoyance. A few may drop a few coins into the hand in a hurry, hoping that other ragged pursuers won't immediately appear on the scene. For many reasons, giving money is not the best response to an outstretched hand. Many world travelers have discovered that the greatest gift they can give is their time and respect. Everyone needs recognition, to be seen as worthy of being known, to feel appreciated and loved. And I believe that everyone is worthy and worth knowing. From the story, what position of the beggars in the author's mind might be? A) equal B) superior C) lower D) valuable

Anyone can try to lead a group, but not every individual is cut out for leadership. The better leaders possess a few qualities that can mean the difference between the success and failure of the group. These aret he qualities the leader of higher rank will look for when choosing a leader for a group, or when evaluating the performance of a leader. They're also the qualities team members want in a group leader, and appreciate when they find them. Take Responsibility Group leaders might share tasks around a group as necessary, but eventually a group leader needs to be able to accept that responsibility lies on her shoulders. That means that if things go wrong in a group project, she's the one who must accept the consequences and work out what mistakes were made. The group leader won't always have the power to control everything group members do, but she should be ready to admit any mistakes the group has made as a result of her leadership. Concern for Members The group leader has a commitment to the task or project at hand, but perhaps more importantly, he has a real concern for each and every person who is part of his group. This means getting to know the strengths, weaknesses and goals of team members, as well as making time to build the group through collective activities. The group leader should make sure that everyone is included, even if an individual is new to a group. Good Listener The group leader needs to be able to listen to the suggestions, complaints   and ideas of group members. Not only will this allow complaints to be addressed and potentially suitable ideas to be put into practice, but a leader who listens will also encourage group members to share their concerns and thoughts,creating an atmosphere of free speech and productivity. According to "Concerns for members", which of the following is a good quality of a leader? A) fair B) reliable C) determined D) generous

The health-care economy is filled with unusual and even unique economic relationships. One of the least understood involves the peculiar roles of producer or "provider" and purchaser or "consumer" in the typical doctor-patient relationship. In most sectors of the economy, it is the seller who attempts to attract a potential buyer with various appealing factors of price, quality, and use, and it is the buyer who makes the decision. Such condition, however, is not common in most of the health-care industry. In the health-care industry, the doctor-patient relationship is the mirror image of the ordinary relationship between producer and consumer. Once an individual has chosen to see a physician -- and even then there may be no real choice -- it is the physician who usually makes all significant purchasing decisions: whether the patient should return "next Wednesday", whether X-rays are needed, whether drugs should be prescribed, etc. It is rare that a patient will challenge such professional decisions or raise in advance questions about price, especially when the disease is regarded as serious. This is particularly significant in relation to hospital care. The physician must certify the need for hospitalization, determine what procedures will be performed, and announce when the patient may be discharged. The patient may be consulted about some of the decisions, but in general it is the doctor's judgments that are final. Little wonder then that in the eye of the hospital it is the physician who is the real "consumer". As a consequence, the medical staff represents the "power center" in hospital policy and decision-making, not the administration. Although usually there are in this situation four identifiable participants-- the physician, the hospital, the patient, and the payer (generally an insurance carrier or government)-- the physician makes the essential decisions for all of them. The hospital becomes an extension of the physician; the payer generally meets most of the bills generated by the... The author is most probably leading up to   _  . A) a proposal to control medical costs B) a study of lawsuits against doctors for malpractice C) an analysis of the cause of inflation   in the US D) a discussion of a new medical treatment
