Read the following article and select the best answer. Article: The effects of air pollution on natural conditions have been a disturbing problem for many years. Some scientists hold the view that the air inside houses may be more dangerous than the air outside. It may even be one hundred times worse. Most scientists agree that every modern house has some kind of indoor pollution, which can cause a person to feel tired, to suffer eye pain, headache and other problems. Believe it or not, some pollutants can cause breathing diseases of blood and even cancer. What made us feel relieved is that there's growing concern about the problem now. It is true that when builders began constructing houses and offices they did not want to waste energy. they built buildings that prevented or limited the flow of air between inside and outside. For the same purpose, man-made building materials were employed to build houses, which are now known to let out some harmful gases. Facing the serious challenge, scientists have been searching for a way to handle the problem. To everyone's delight, they discovered a natural pollution control system for building--green plants, though they do not really know how plants control air pollution. Scientists suppose that a plant's leaves absorb or take in the pollutants and in exchange gives out oxygen through its leaves and tiny organizations on its roots. Therefore they recommend that all buildings should have one large plant or several small plants inside for every nine square meters of space. Because studies indicate that different plants absorb different chemicals, the most effective way to clean the air is to use different kinds of plants. In conclusion, having green plants inside your house can make it a prettier and healthier place. Why not try? Question: According to scientists, some kind of indoor pollution can be found in _ . - every old building - every modern house - all kinds of houses - all kinds of offices
every modern house

Read the following article and select the best answer. Article: The city of Vienna has always been popular for its famous physicians. Around the year 1482 one such well-known physician was Dr. Paul Urssenbeck. His fame came from his ability to predict with certainty whether a patient would recover his or her health or would die. He thus became known as the doctor of death. In his earlier years, he followed the trade of a poor but honest weaver in the town of Deckendorf near Straudigen in Bavaria. It was a time of famine , and he, his wife, and their eleven children were in great need. Then a twelfth child was born, and they could find no one to serve as its godparent. As a last chance, the poor weaver walked to a nearby village and asked an old friend to serve as godfather, but met only rejection. Disappointed and frustrated, the poor man made his way back to his family. While walking sorrowfully through the dense forest toward his home, he said, "If only I could die." Suddenly a tall figure dressed in a dark cloak appeared before him, saying, "You called me. I am Death. What can I do for you?" As much as the man had previously wanted to die, he now wanted to live. "I am seeking a godfather for my youngest child. But I cannot find anyone who will serve as his godparent," answered the weaver sadly. "I will accept this responsibility," said Death. And thus it happened. Following the baptism , the mysterious godfather took the father aside and said, "Since I own neither gold nor silver to give to your child as a baptism present, I will make you into the most famous doctor of all times. Whenever you are called to a sick person, I--invisible to others--will seat myself either to the head or to the feet of the patient. If I am seated at the head, then this will show you that hope for recovery exists. If I am seated at the feet, then the patient will die." Through this gift, the weaver was able to cure many illnesses, for he knew whether the patient who had sought his treatment would be helped by medications, or whether he would die. Soon the previously poor weaver became a... Question: Which of the following CANNOT be used to describe Dr.Urssenbeck? - Grateful - Greedy - Dishonest - Unfaithful
(Answer)
Grateful

Question: Read the following article and select the best answer. Article: Climate change, global warming, the greenhouse effect ... these days nobody denies that there is something strange and worrying happening to the atmosphere. Scientists are puzzled by the rise in carbon dioxide in the atmosphere. They are afraid that the world may be a short way from what they refer to as uncontrolled global warming. At Mauna Loa Observatory in Hawaii, meteorologists have been carefully monitoring the amount of carbon dioxide in the Earth's atmosphere for the past 50 years. Until recently, there has been a gradual increase of around 1.5 parts per million (ppm). In 2013 the figure rose to 2.08 ppm and in the following year they registered an increase of 2.54 ppm. .Climate analysts feel that it istoo soon to draw conclusions about the phenomenon although the public are concerned that the carbon dioxide emissions are getting out of control. Jason Samenow, the chief meteorologist in the American National Weather Service,thinks that instead of having decades to find a solution to the problem, people might have only a few years. He believes that the Earth's natural systems for absorbing the gas are breaking down resulting in the uncontrolled green house effect. He insists that this is something that could happen if the Earth'stemperatures rose to such a degree that it was unable to contain the heat. . One interesting aspect of this climate change ng down resulting in the uncontrolled greenhouse effect. He insists that this is something that could happen if the Earth's temperatures rose to such a degree that it was unable to contain the heat.is that it is not happening in a uniform way around the world. Carbon dioxide levels in the South Pole are noticeably lower. This suggests that something has happened in the northern hemisphere that set off the rise. Forest fires in North America might hold the answer to the puzzle, along with very hot summers in Europe. The 2014 heat wave was certainly out of the ordinary. Statistics claim that more than 30,000 people lost their lives as a direct result of the... Question: What opinion does Jason Samenow hold on the gradual increase of carbon dioxide? - People still have decades to solve this problem. - Uncontrolled greenhouse effect may happen in some situation. - The Earth's natural systems for absorbing the gas have completely broken down. - The public shouldn't be responsible for carbon dioxide emissions.
Answer:
Uncontrolled greenhouse effect may happen in some situation.
