Ques:Read the following article and select the best answer. Article: Technology: Taking the good without the bad? Very soon, unimaginably powerful technologies will remake our lives.This could have dangerous consequences, especially because we may not even understand the basic science underlyi ng them.There's a growing gap between our technological capability and our basic scientific understanding.We can do very clever things with the technology of the future without necessarily understanding some of the science underneath, and that is very dangerous. The technologies that are particularly dangerous over the next hundred years are nanotechnology , artificial intelligence and biotechnology.The benefits that they will bring are beyond doubt.But they are going to be very, very dangerous.I'm working in the field of artificial intelligence.I have a model design for something that might be 50,000 million times smarter than the human brain.Target date is 2010.The only thing that's not possible in the film Terminator is that the people win.If you're fighting against technology w hich is 50,000 million times smarter than you, you probably will not win. Nanotechnology.We've all heard of the grey glue problem, that self-replicating nanotech devices might keep on copying until the world has become sticky glue.And certainly in biotechnology, we've really got a big problem because it's converging with nanotechnology and IT.Once you start mixing nanotech with organisms and you start feeding nanotech-enabled bacteria, we can really go an awful lot further than the Borg in Star Trek .And those superhuman organisms might not like us very much. Eventually these technologies will become routine.That's a threat to humanity.I don't think it's possible to slow it down.So what we need to do is accelerate the scientific research and try to get some extra tools.The problems facing us in the future are getting bigger and bigger.I think if we don't get some proper science done, the future is hopeless indeed. Question: From the text, we know that the author's greatest concern is _ . - our lack of technological understanding of the process involved - our lack of technological capability - creating technology without really understanding the basic science - Our refusal to face the consequences of the technology we create

Ans:creating technology without really understanding the basic science

Ques:Read the following article and select the best answer. Article: Mr. Patrick was new to the school and to us. Even though he was a great teacher, he seemed rather like a character out of a horror movie. He didn't look that bad, but somehow, he looked extremely scary to me. Some kids began to believe that he was a murderer or a ghost; some believed he was mad and a few believed that he might have suffered a lot in his life. I was one of those 'few'. One day I gathered up my courage and headed towards the school garden. He was, as usual, sitting on a bench alone. I breathed heavily a few times and then walked towards him. "How are you?" I asked with my voice crackling. He managed to say, "Fine." "Well, good to know," I tried to be happy. "Hmmm..." was all I heard. "What's up with you?" then seeing a puzzled look on his face, I tried to be more formal and respectful. "I mean, why aren't you like all other people in the school? Why are you always so quiet and sad? Why..." "No dear, some things are better left unsaid," he said gloomily. "Oh no sir, nothing is better left unsaid. If you want to share your feelings with me and reduce the pain of your heart, you are free to do so. I promise I will never ever tell anyone." "With you? You are just a little girl; what will you understand?" I was somehow offended but still I managed to persuade him, "So what, Sir? You see, if you tell me your problem, you will have a light heart and you will have the feeling that someone somewhere cares about you." "Oh okay, that was a very nice belief indeed; let's take a walk and I will let you know everything." Soon after our little talk, there was a visible change on his face. Later that day in the class, there was a smile on his face. Question: Mr. Patrick was thought by the author to _ - be a murderer or a ghost - be mad - have suffered a lot - have a special personality

Ans:have suffered a lot

Ques:Read the following article and select the best answer. Article: What we eat, when we eat or how we eat is usually considered to be an everyday eating habit. Good eating habits are very important for our health. Most of us would rather eat sweets and ice-cream than meat and rice. Sweets and ice-cream are not bad for the stomach if we eat them at the end of a meal. But we should also know that if we eat them before a meal, they will spoil our appetite . It is a good habit for us to eat our meal at the same time each day. When we feel hungry, it is a sign that our body needs a good supply. When we feel angry or excited, we may not want to eat. A long time ago, in England some judges used to decide whether a man was telling the truth by giving him some dry bread. If he could not swallow the bread, it was a sign that he wasn't telling the truth. He was telling lies. Although this seems very strange and rather foolish, it is indeed an excellent way of finding out the truth. A man who is worrying about something has difficulty in swallowing anything dry. Because he is worrying, he loses his appetite and does not want to eat. Question: A man who is angry has _ . - a good appetite - a poor appetite - a liking for ice-cream - a strong desire to drink some cold water

Ans:a poor appetite
