Read the following article and select the best answer. Article: I never thought I would have a life-changing experience at Wal-Mart. Although my thoughts were only on speed, the checkout line I was standing in wasn't moving as quickly as I wanted, and I glanced toward the cashier. There stood a man in his seventies, wearing glasses and a nice smile. I thought, well, he's an old guy! For the next few minutes I watched him. He greeted every customer before scanning the items. Sure, his words were the usual, "How's it going?" But he did something different--he actually listened to people. Then he would respond to what they had said and engage them in brief conversation. I thought it was odd. I has grown accustomed to people asking me how I was doing simply out of robotic conversational habit. After a while, you don't give any thought to the question and just mumble something back. I could say, "I just found out I have six months to live," and someone would reply, "Have a great day!" But that wasn't the end. He gave them the change, walked around the counter, and extended his right hand in an act of friendship. He looked the customers in the eyes. "I sure want to thank you for shopping here today," he told them. "You have a great day. Bye-bye." The looks on the faces of the customers were priceless. There were smiles and some sheepish grins. All had been touched by his simple gesture--and in a place they never expected. They would gather their things and walk out, smiling. Of course, he did the same to me and I got to know his name--Marty. Who was that guy? It was as if Sam Walton had come back from the dead and invaded this old guy's body. I had never walked away from that shop feeling like that.

In our modern world, discomfort is considered a terrible thing. If not terrible, at least a thing of the past. Dishwashers, washing machines, computers, remote controls--yes, they add convenience, but also a level of comfort our forefathers did not enjoy. As pain of any kind discourages happiness, we tend to reason, anything that compromises our ability to feel good must be bad. And that's also particularly true for our careers. Success makes us feel great, not terrible. Such a view, however, is a matter of personal opinion. And it may blind us to hidden opportunities. Artists throughout history have tried to experience suffering, instinctively if not consciously, to produce works that explore the darker hidden sides of the human condition. This was done, in part, because pain is a reality of life for everybody in some form at some time. Pain is something everybody can relate to. And pain makes a person very present. For such artists, to relieve or to deny pain would be to block the creative thinking, which drives them to explore and express. In fact, Germans have a term for this melancholia, " _ ", which means "suffering from the world." Writers, from Lord Byron to Kurt Vonnegut, have used the term to describe the psychological pain encountered along life's roller-coaster journey. It was not to be avoided; it was to be understood, investigated and employed. So I propose that discomfort is good for us. Or, put another way, it tells us that something needs to be addressed. It stretches us by forcing us to view our circumstances through a wholly different lens. Because we're drawn to safety and security, we do our best to create pleasant comfort zones for ourselves and our loved ones through the cars we drive, the homes we live in, and the places we work. But by resisting discomfort, we deny ourselves an important opportunity: the chance to shake ourselves out of our predictable perspectives and allow ourselves to make... Question: By writing this passage, the author tries to _ . - criticize a world full of comfort - explain why discomfort is good for us - persuade people to lead a life full of discomfort - blame those who enjoy an easy life
explain why discomfort is good for us

Q: Read the following article and select the best answer. Article: An earthquake is a trembling or shaking of the ground caused by the sudden release of energy stored in the rocks below the surface. Generally, earthquakes last only seconds. Strong ground shaking during a medium to large earthquake generally lasts about 10 to 30 seconds. Aftershocks can occur once in a while for weeks or even months. Many people think that there is an "earthquake season" or a kind of " earthquake weather ".As a matter of fact, there isn't. Earthquakes can occur at any time of the year and at time of day or night. Earthquakes occur under all weather conditions-sunny, wet. or cold without any special weather tendency . Also, you don't need to worry that the ground will open up and swallow people when earthquakes occur. Open ground cracks may form during an earthquake, for example, to land sliding or ground falling. However, such cracks tend to be open gaps (they don't " swallow") that a person could stand in afterwards. The safest place in an earthquake is an open field because buildings and falling objects can injure or kill you. If you are indoors, when you feel the ground start to shake, take cover immediately under a table or strong piece of furniture, placing something between falling objects and yourself. Don't " attempt to use the stairs or an elevator to get out of the building.. Question: The reason why there isn't "earthquake weather" is that. _ . - an earthquake only lasts seconds and doesn't happen frequently. - an earthquake can happen at any time and in any kind of weather. - when an earthquake happens is related to the weather - earthquakes don't change with the seasons
A: an earthquake can happen at any time and in any kind of weather.

Read the following article and select the best answer. Article: Research shows that humans switch from selfish to unselfish behavior when they are watched. Do you? A picture of a set of eyes on a computer screen can cause a change in the way people act. Even images of eyes on a charity donation, collection box encourage people to be unselfish, because people put more money in a collection box that has a picture of eyes on it than they do when a flower symbol is on the box. Manfred Milinski from the Max-Planck Institute for Evolutionary Biology in Germany and Bettina Rockenbach of the University of Berlin, the authors of a new study, found that people act better when they are being watched because they feel they will be rewarded for good behavior. Their report also referred to other research showing that this response of behaving well when watched is somehow _ into humans and people respond this way unconsciously, or without realizing it. It is not just humans that act unselfishly when they are being watched. A fish called the grooming fish cleans other fish. When other fish are around, it is gentler. When no other fish are around, however, the grooming fish bites chunks from the fish it is supposed to be cleaning. The researchers suggest that the best way to get people to behave in the correct way is to make them feel watched. This could be the reason for the success of a famous American army poster. On it was a picture of an elderly man staring fiercely and pointing, it appeared, to the person who was looking at the poster. Under the picture was the caption 'I Want You' It encouraged hundreds of thousands of young American men to join the army during the Second World War to fight the Germans and Japanese. Question: According to the report, why does a person behave better when he feels he is being watched? - He does not want to be shamed by others. - He needs to show he is a good person. - He desires others to like him more. - He feels he will receive some social reward.
