(Question)
Read the following article and select the best answer. Article: First aid is emergency care for a victim of sudden illness or injury until more skillful medical treatment is available. It may save a life or improve certain vital signs including pulse, temperature, a clear airway, and breathing. In minor emergencies, first aid may prevent a victim's condition from turning worse and provide relief from pain. First aid must be done as quickly as possible. In the case of the seriously injured, a few minutes can make the difference between complete recovery and loss of life. First-aid measures depend upon a victim's needs and the provider's level of knowledge and skill. Knowing what not to do in an emergency is as important as knowing what to do. Improperly moving a person with a neck injury, for example, can lead to permanent spinal injury and paralysis . Despite the variety of injuries possible, several principles of first aid apply to all emergencies. The first step is to call for professional medical help. The victim, if conscious, should be reassured that medical aid has been requested, and asked for permission to provide any first aid. Next, assess the scene, asking other people or the injured person's family or friends about details of the injury or illness, any care that may have already been given, and pre-existing conditions such as diabetes or heart trouble. The victim should be checked for a medical card that describes special medical conditions. Unless the accident scene becomes unsafe or the victim may suffer further injury, do not move the victim. First aid requires rapid assessment of victims to determine whether life-threatening conditions exist. One method for evaluating a victim's condition is known by the acronym ABC, which stands for: A---Airway: is it open and clear? B---Breathing: is the person breathing? Look, listen, and feel for breathing. C---Circulation: is there a pulse? Is the person bleeding extremely? Check skin color and temperature for additional indications of circulation problems. Question: Before we administer first aid to a victim, it is very important for us _ . - to make sure what to do and what not to do - to refer to all kinds of handbooks on first aid - to remove the ring or bracelet he/she may be wearing - to take him/her to a hospital at once
(Answer)
to make sure what to do and what not to do

Ques: Read the following article and select the best answer. Article: In March 2012, researchers in the United States announce that they have developed the first wirelessly controlled device that can supply a drug directly into the body. A small chip is implanted under the skin. It contains the medicine, which it releases at preset times. The developers say the device could improve the lives of millions of people who take medicine for long-term illnesses. A company called MicroCHIPS began developing the device about fifteen years ago. Last month, the company released the results of its first successful tests in humans. The tests took place in Denmark with seven women with osteoporosis. Osteoporosis causes bones to become weak and break easily. The disorder is common among older people, especially women. Many patients have to give themselves daily injections of medicine. One type of treatment requires injections for two years. Robert farra is the president of MicroCHIPS. He says many patients stop taking the medicine because of the pain and stress of the injections and that only twenty-five percent of the patients will go through the entire twenty-four months of treatment. The microchip is a few centimeters long. It has small sections that each hold a single dose of medicine. Mr. Farra says the device has to be programmed with the times to release the drug and that doctors will be able to reprogram the device from a computer or even a cell phone. The seven women in the study were aged sixty-five to seventy. The researchers say the implants were just as effective as daily injections. And they say the dosage amounts were more exact than patients often give themselves. The microchips in the study held only twenty doses of medicine. Mr. Farra and his team are now designing a version that could hold a full year's worth of medicine. Robert Farra says, "The new version may take us two years, and then we may be required to do two additional trials, taking about four years before the device is available on the commercial scale." Question: Which of the following is TRUE? - The seven women participants all got over the disease after the test. - The company MicroCHIPS began developing the device in about 1998. - the test with the women took seven years. - It may be six years before the device is put to commercial use.
Ans: It may be six years before the device is put to commercial use.

Question: Read the following article and select the best answer. Article: Every autumn, as families across the United States get ready to send their kids to college, the economics of higher education receive renewed attention. College is expensive and becoming more so in the U. S. The situation raises two questions: Why does it cost so much, and how can students and their families afford it? Several studies published in the past few weeks reflect on these questions. The findings provide comfort to poor families. First, it appears that only the minority actually pay the "high price". A study by the US Education Department's National Center for Education Statistics found that 55 percent of college students last year received some forms of help--scholarships, loans or jobs. Other factors are also at work. The government has increased the size of its grants to lower-income students. Grants, unlike loans, don't have to he repaid and are awarded only to college students who have not earned a bachelor's or professional degree. At the same time, most colleges are spending more on undergraduate education than they are collecting in tuition fees. A study, which is part of the Williams College Project on the Economics of Higher Education, reaches the conclusion that on average colleges "subsidize " their students. The results of these studies, however, leave unanswered the questions of whether educational costs are higher than they need to be. Some experts argue that much of the college cost results from educational competition for fame, students and facilities. This puts upward pressure on tuition, hut many colleges feel that good fame will enable them to attract students even if they charge them more. Therefore, until something important changes in the marketplace, costs seem likely to continue rising. And American families will continue to beat down the doors of the high price "college in the end. Question: The writer of this passage seems to hold the opinion that _ . - college fees rise too fast for poor families. - poor people should borrow money from banks - poor people don't need to send their children to college - colleges should get more money to improve themselves
Answer:
college fees rise too fast for poor families.
