Read the following article and select the best answer. Article: Is there a nationwide shortage of nurses? It's hard to say. However, some characteristic symptoms often indicate that there is indeed a shortage. One symptom is the vacancy rate, or the percentage of budgeted positions that are unfilled. New England's hospitals currently report that an average of 7 to 12 percent of their registered nurse positions are vacant, the highest level since the last shortage in the late 1980s. Vermont has a ly low vacancy rate, at 7.8 percent. But its vacancies were at 1.2 percent just five years ago. Another symptom is the increased use of stopgap measures to fill empty positions. For instance, many nurses report an _ in how frequently they are asked to stay past their shifts. According to Murphy, working in the St. Elizabeth's Hospital, "The shortage has definitely created a lot of opportunities of overtime for our nurses, whether they want them or not." Similarly, a national survey of registered nurses shows that in an average week, nurses in the U.S. work 2.4 more hours than they are scheduled to. Much of this extra time is voluntary, as nurses earn overtime pay when they stay to fill in blanks in the schedule. When they can't fill open positions by more traditional means, health care providers hire temporary staff to tide them over. Travelling workers are the largest part of the temporary health care workforce, hired for thirteen-week reduction at health care facilities facing short-term lack of workers. Temporary workers, mainly nurses, cost hospitals $ 7.2 billion in 2000. "Any successful solution to the shortage depends on convincing more people to become nurses, and that is not an easy goal to reach. To achieve it," says Buerhaus, "society needs to place more value on nursing. Legislation can't do that - it should come from people." And if this continues, we might have to learn to care for ourselves in the hospital. Question: According to Buerhaus, what is a successful solution to the nurse shortage? - To convince people of the benefits of being a nurse. - To ask the government for help to work out specific legislation. - To publicize the past achievements of nurses. - To make people aware of the importance of being a nurse.
To make people aware of the importance of being a nurse.

Read the following article and select the best answer. Article: About 12,000 years ago- long before the famous UFO crash make headlines in America--an alien spaceship crashed in China. And their descendants are still living in a faraway Chinese village today! That is the mind-bending claim made in the new book Out of Time and Place, a collection of reports from the files of Fate, a magazine edited by Terry O'Neil. The story first came to light in 1937 when an expedition led by Chi Pu-Tei came across a group of caves deep in the Bayan-Kara-Ula Mountains. In the caves were found strange-looking skeletons with big heads and small, slender bodies--closely matching typical descriptions of space aliens. The explorers also uncovered 716 mysterious stone discs with strange hieroglyphics on them. In Qinghai Province, where the mountains lie, ancient stories tell of small, skinny beings with oversize heads who came from the sky long long ago. And to this day, locals live in fear of attack from strange-looking creatures from above. And there is more. In 1947, British scientist Karyl Robin-Evans led an expedition into the mountains and discovered a group of dwarfs who called themselves the Droza. "They told him that their ancestors came from a planet in the Sirius system and crashed in this mountain area a long time ago," writes Hausdorf, "Many of them were killed, but survivors adapted to living on this rough planet far from home." For decades, Robin-Evans' claims were dismissed as nonsense. But in 1995, the Associated Press reported that in the region a village named Huilong had been discovered--populated by 120 dwarfs ranging from 3-foot-10 to 2-foot-1tall.Hausdorf asks, "Could these people be the last living descendants of the survivors of the legendary UGO crash--the Chinese Roswell?" Question: What can be safely concluded from the passage? - This passage is a piece of science news recently issued. - Chinese are descendants to the survivors of the alien spaceship crash - The UFO crash in the Byan-Kara-Ula Mountains has recently been seen - Many people are curious about aliens from outer space
(Answer)
Many people are curious about aliens from outer space

Question: Read the following article and select the best answer. Article: Public caught up in argument over safety of genetically modified or simply GM products, report Zhang Lei and Zhong Nan in Beijing. More than 300 people gathered to enjoy a bowl of porridge made from genetically modified food on Saturday, an attempt to quell public fears about the safety of the product. The first China Golden Rice Tasting Event was held at Huazhong Agricultural University in Wuhan, Hubei province, sparking another round in the nationwide debate about the safety of GM crops, often called "Frankenfood" by opponents. Similar events have been held in more than 28 cities since May, the university said. Both the pro and anti camps have posted conflicting comments on the Internet, with each providing evidence to back up their beliefs, but the exchanges are becoming increasingly bitter. Jiang Tao, a senior engineer at the Center for Agricultural Resources Research at the Chinese Academy of Sciences, who is in favor of GM foods, was annoyed about what he called "amateurs" spreading rumors. "Just look at the people who are opposed to GM foods; can you find anyone from a related field in the scientific community?" he asked. Jiang also accused the anti-GM lobby of repeatedly using outdated or inaccurate data to support an "incorrect" stance. Chen Yunfa, an independent researcher into the Yangtze River Delta economy, recently wrote a commentary on the Internet news portal Eastday in which he criticized the actions of the 61 scientists, saying they had gone "beyond their proper duty". He suggested that large multinational corporations might be behind the letter and similar incidents, prompted by a desire to freeze China's patent hybrid rice technology out of the market. To support his contentions, Chen said that GM rice, first produced by scientists in the US, still hasn't gained official approval from the US government. However, the US authorities have actually granted licenses to six varieties of GM rice. The commercial planting of two varieties - anti-herbicide (BAR) transgenic rice LL RICE 06 and LL... Question: Why did more than 300 people enjoy porridge made from genetically modified food? - To show evidence that GM products are dangerous. - To support that the first China Golden Rice Tasting is safe. - To rid public of fears and worries about the safety of GM foods. - To draw public's attention to nationwide planting of GM products.
Answer:
To rid public of fears and worries about the safety of GM foods.
