Question: Article: Sensing phantom phone vibrations is a strangely common experience. Around 80% of us have imagined a phone vibrating in our pockets when it's actually completely still. Almost 30% of us have also heard non-existent ringing. Are these signs of madness caused by digital culture? Not at all. In fact, phantom vibrations and ringing indicate a fundamental principle in psychology. Psychologists use a concept called Signal Detection Theory to guide their thinking about the problem of perceptual judgments. Working through the example of phone vibrations, we can see how this theory explains why they are a common and unavoidable part of healthy mental function. When your phone is in your pocket, the world is in one of two possible states: the phone is either ringing or not. You also have two possible states of mind: the judgment that the phone is ringing, or the judgment that it isn't. Obviously you'd like to match these states in the correct way. True vibrations should go with "it's ringing", and no vibrations should go with "it's not ringing". Signal detection theory calls these faithful matches a "hit" and a "correct rejection" But there are two other possible combinations: you could mismatch true vibrations with "it's not ringing" (a "miss"); or mismatch the absence of vibrations with "it's ringing" (a "false alarm"). This second kind of mismatch is what's going on when you imagine a phantom phone vibration. What does that mean in terms of your phone? We can assume that people like to notice when their phone is ringing, and that most people hate missing a call. This means their perceptual systems have adjusted their bias to a level that makes misses unlikely. The unavoidable cost is a raised likelihood of false alarms of phantom phone vibrations. The trade-off between false alarms and misses also explains why we all have to put up with fire alarms going off when there isn't a fire. It isn't that the alarms are badly designed, but rather that they are very sensible to smoke and heat and biased to avoid missing a real fire at all costs. The outcome is a rise in the number of false alarms. These are inconvenient, but nowhere near as inconvenient as burning to death in your bed or office. The alarms are designed to err on the side of caution.

Question: Article: I am sure that everybody in his/her life has used computers. Nowadays you can feel their presence everywhere at home,at school,at work and they certainly make life easier.On the other hand,there are people who can't work with them. Anyway,I believe their presence is a good thing. Life with them seems easier, less difficult and more comfortable You can use them to choose your meal,to withdraw your money, and also save your time,because these operations are all controlled by computers. Therefore you can hardly imagine the modern world without them;the whole planet seems to be one big computer society. Nevertheless,problems can often appear in this area, too.To have a computer means you have to be quite well-off and have the necessary skills to use it.However,think about questions like "Are computers so available for everyone, or rich and poor people,for people from villages and people from cities. Aren't they too expensive?Is everyone able to learn how to use them and not everyone has the chance to access and work with them,how could everything in the future be dependent on them?"Therefore,I think our society will be split into two parts.One part will work with them and enjoy the benefits that computers can bring and the other part will be pushed out and will actually be far behind the other group. Another question that bothers me is,on the one hand,computers are important and good things in our life,but they aren't everything.They are good as a help at school,quite often as entertainment,especially for young people,as an necessary tool to help in research etc,but I think we shouldn't be so dependent on them,because computers are only machines and machines can't feel anything be human and sympathetic,and every action performed by computer can be interfered with another person,which could cause these machines to crash or work badly. In conclusion,I would like to say I am not against computers.I use computers,too,but people should be wary all the time.
Question: The writer's main purpose in writing the passage is _
Options: (A) to encourage us to use computers in our society (B) to advise us to say no to computers from now on (C) to remind us to care about the problems that computers bring. (D) to inform us that the computer has become a necessary part of our life

Answer: C
