Question: I'm taking a test and have to guess the right answer to the question after the article. Article: What would you think if someone suggested knocking down St Paul's cathedral to widen the road,or pulling down Big Ben to make way for a car park? It'd be ridiculous,right? But when it comes to devastation of the natural world,we aren't so easily shocked.But we should be...or we'll be in a lot of trouble! _ Ancient forests are destroyed.Wetlands are becoming dry.Woodland is disappearing,all in the name of progress.This is bad in itself,but it's devastating for biodiversity. Biodiversity refers to the variety of plants,animals and other living things which are all inter-connected.The ecological services provided by biodiversity are vital to everyday life.The air we breathe is a product of photosynthesis by green plants.In fact,all life on earth exists thanks to the benefit of biodiversity.More than 90 percent of the calories consumed by people worldwide are produced from 80 plant species.And 30 percent of medicines are developed from plants and animals.Maintaining a wide diversity of species in each ecosystem is necessary to preserve all living things. The loss of biodiversity could be devastating."It is wrong to think that biodiversity can be reduced indefinitely without threatening humans," said Harvard University biologist Edward O Wilson,known as "the father of biodiversity".He warned,"We are about to reach a critical point beyond which biodiversity loss will be unavoidable." But what can we do? The problem is that the concept of biodiversity is so vague.People might care about giant pandas,but it is much harder to excite them about the fate of tiny sea creatures which are being boiled to death in the cooling systems of power stations along coastlines.The Guardian newspaper is trying to help.It has started the Biodiversity 100 campaign to try to convince governments around the world to take action to deal with the widespread concerns about biodiversity.This includes persuading the UK government to create a series of marine reserves to change the decrease in the sea-life caused by industrial... Question: What can we infer from the passage? Options: A: Plenty of marine reserves have been set up in the world. B: Fishing sharks is illegal around the world. C: It's harmful to catch tiny organisms in the river. D: The Guardian newspaper has done a lot for biodiversity.
Answer: D

Question: I'm taking a test and have to guess the right answer to the question after the article. Article: They say that sticks and stones may break your bones, but words will never hurt you. Yet childhood bullying really can damage your long-term health. Gone are the days when bullying was considered an unavoidable and finally harmless part of growing up -- just last month we learned that childhood bullying can lead to poorer mental health even into middle age. Now William Copeland at Duke University in Durham, North Carolina, and his colleagues have shown that it can have lasting physiological effects too. They tracked 1,420 nine-year-olds right through their teens. Each child was seen up to nine times during the study and asked about bullying. The team then measured levels of C-reactive protein (CRP) in their blood. CRP is a marker of inflammation linked to higher risk of cardiovascular disease and problems like diabetes. "Because we were collecting biological samples throughout, we were able to look at CRP levels in subjects _ their bullying involvement." says Copeland. "This really gives us an idea of the changes bullying brings about." Although CRP levels naturally rise in everyone during adolescence, levels were highest in children who reported suffering from bullies. Even at the ages of 19 and 21, children who had once been bullied had CRP levels about 1.4 times higher than peers who were neither wrongdoers nor victims. In a cruel twist, the bullies had the lowest levels of all, suggesting they didn't suffer the same health risks. They may even see a benefit from their behavior, though Copeland stresses it doesn't defend their actions. "The goal would instead be to find other ways to produce this protective effect without it being at someone else's expense." he says. Andrea Danese at King's College London has before shown that ill-treatment during childhood can lead to high levels of inflammation in adult life. "This new study is a helpful addition in showing that these effects extend to another important childhood stressor." he says. He suggests that care workers monitor levels of CRP in children... Question: What do you know about CRP? Options: A: It relates directly to diabetes. B: It is a sign of the inflammation. C: It is a sign of cardiovascular disease. D: It is a sign of physiological effects caused by bullying.
Answer: B

Question: I'm taking a test and have to guess the right answer to the question after the article. Article: What is the nature of the scientific attitude, the attitude of the man or woman who studies and applies physics, biology, chemistry, geology, engineering, medicine or any other science? We all know that science plays an important role in our societies. However, many people believe that our progress depends on two different aspects of science. The first aspect is the application of the machines, products and systems of knowledge that scientists and technologists develop. The second is the application of the special methods of thought and action that scientists use in their work. What are these special methods of thinking and acting? First of all, it seems that a successful scientist is curious - he wants to find out how and why the universe works. He usually pays attention to problems which he notices have no satisfying explanation, and looks for relationships even if the data available seem to be unconnected. Moreover, he thinks he can improve the existing conditions and enjoys trying to solve the problems which this involves. He is a good observer, accurate, patient and objective and uses the facts he observes to the fullest. For example, trained observers obtain a very large amount of information about a star mainly from the accurate analysis of the simple lines that appear in a spectrum . He does not accept statements which are not based on the most complete evidence available. He rejects authority as the only basis for truth. Scientists always check statements and make experiments carefully and objectively. Furthermore, he does not readily accept his own idea, since he knows that man is the least reliable of scientific instruments and that a number of factors tend to disturb objective investigation. Lastly, he is full of imagination since he often has to look for relationships in data which are not only complex but also frequently incomplete. Furthermore, he needs imagination if he wants to guess how processes work and how events take place. These seem to be some of the ways in which a successful... Question: Which word can be used to describe the data that a good scientist uses? Options: A: complete B: objective C: complicated D: accurate
Answer:
C
