Article: Robots make me nervous-especially the ones which seem to think for themselves.I was embarrassed to admit this till I heard that Bill Gates,the founder of Microsoft,felt the same way.Gates said in an interview with the website Reddit:"I am in the camp that is concerned about super intelligence.First the machines will do a lot of jobs for us and not be super intelligent.That should be positive if we manage well.A few decades after that though the intelligence is strong enough to be a concern." Well,maybe I don't have to worry about my laptop and kitchen appliances yet.After I use them I can always pull the plug.But in the future,machines might find a way to prevent us from switching them off.There's a scary thought! Professor Stephen Hawking warned a few months ago about the possibility that artificial intelligence could evolve and end up beyond human contro1.He suggested that machines could" _ the end of the human race". Maybe the problem with computers too clever for us is not that they are evil or rebellious.What could put us in danger is that they might be too efficient.That's what philosopher Nick Bostrom from the Future of Humanity Institute at Oxford University believes.He says that machines are indifferent to humans and in pursuit of their own goals,the destruction of people might be just collateral damage.A machine would not take pity on you. I'm glad my machines at home are"dumb".All my vacuum cleaner wants to take over is the carpet in my living room.Let's hope they don't create an appliance which wants to take over the world!
Question: We can conclude from Gates'statements that _ .
Options: (A) he is embarrassed that he is afraid of robots (B) he doesn't think machines are intelligent (C) machines should be fully employed (D) machines'super intelligence should be a concern
Asnwer: D

Article: It was a sunny winter day. I had gone down the tower when a blind man came toward me. He kept close to the wall, touching it lightly with his arm. I stood still and looked at him walking toward the tower. "What does a blind man want to climb up the tower for?" I wondered, "Not the view certainly, perhaps he wants to jump. "Thinking of this terrible reason, I thought I should follow him. He went up slowly and stopped from time to time. I followed him a few steps behind. When he got to the first corner of the bell tower, I came close to him. "Excuse me," I said as politely as I could, "but I wonder why you came up." "You'd never guess." he said. "Not the view or the fresh air on this winter day?" "No." he said. "Tell me, then." He smiled, "Perhaps climbing up the tower. You have noticed - and yet, not being blind, perhaps you won't - how the sun shines into the tower through the windows here and there, so that one can feel the cool steps suddenly become quite warm, even in winter. But behind the wall there is shade . There is no place so good as this for feeling the difference between light and darkness. Though I'm blind, I also want to feel the happiness brought by the sunlight. In fact, it isn't my first time to be here." He said and seemed as pleased as a child. I had never thought that even a blind man could have his way to enjoy the beautiful life. But we often paid no attention to its value because we never lost it. We went down the tower together and I left him. From then on, I began to treasure what life has given me.

Article: A study made by University of Sussex found that men and women who frequently used several types of technology at the same time had less grey matter in a key part of the brain . The researchers said : " Simultaneously , using mobile phones , laptops and other media devices could change the structure of our brains . " Worryingly , the part of the brain that shrinks is involved in processing emotion . The finding has linked multi-tasking with a shortened attention span , depression , anxiety and lower grades at school . The researchers began by asking 75 healthy men and women how often they divided their attention between different types of technology . This could mean sending a text message while listening to music and checking email , or speaking on the phone while watching TV and surfing the web . The volunteers were then given brain scans which showed they had less grey matter in a region called the anterior cingulated cortex ( ACC ) . The findings held even when differences in personality were taken into account . The study , published in the journal PLOS ONE , is the first to make a link between multi-tasking and the structure of the brain . Researcher KepKeeLoh said : " Media multi-tasking is become more popular in our lives today and there is growing concern about its impacts on our cognition and social-emotional well-being . " He added that more researches are needed to prove that multi-tasking shrinks the brain . This is because it is also possible that people with less grey matter in the ACC are more likely to use lots of devices simultaneously . Scientists have previously described brain structure can be altered on prolonged exposure to new environments and experience . Other studies have shown that training - such as learning magic or taxi drivers learning the map of London - can increase grey matter densities in certain parts .
Question: What can we learn about grey matter from the passage ?
Options: (A) Watching the TV for a long time can reduce grey matter . (B) The decrease of grey matter in the ACC affects emotion . (C) People with less grey matter prefer to use media devices . (D) Taxi drivers in London have more grey matter than others .
