They are usually very different from their partner, and yet all live easier lives because of each other. It is nature's idea of sharing. An example of a partnership is the shark and pilot fish. The pilot fish is a little fish only about nine inches long. He would be. helpless if he hung around by himself in the mighty ocean. He makes up for his size with his smartness. He cleverly swims along beside the shark. When the shark eats, the pilot fish gets the leftovers. And the pilot fish needn't worry about his safety. The shark also gets benefits from this relationship. The pilot fish cleans food scraps and insects from the shark's hide. Another example of depending on each other is the sea anemone and striped clown fish. The sea anemone looks like a flower and has petals that contain poisonous stinging cells. When small fish swim into the petals, the anemone traps and paralyzes them. However,the striped clown fish is able to swim into the poisonous petals without being harmed. When he is in danger, he quickly swims into the sea anemone and is unable to be seen by his enemies. To pay for his safety,the clown fish brings food to the anemone. He also guides other fish into the anemone's deadly trap. Large mammals such as the ox, antelope, rhinoceroses and African buffalo form such a relationship with the red-billed ox-peeker. They provide daily meals for the bird. In fact the bird eats insects. The various large mammals act as a restaurant with a varied menu for the ox-peeker. What do they get in return from the bird? Free beauty treatments! Some plants live together in a beneficial relationship of symbiosis. The fungus does not have chlorophyll that plants need to make food. However, green algae does contain chlorophyll. It is, therefore, able to feed the fungus along with itself. But nothing is free! The fungus repays it by protecting the algae. Since it takes...

Article: One day I walked down to get to my car, thinking about what I had to accomplish and scolding myself for being late for work, but surprisingly the car was nowhere to be found. This was at 8 a.m. in the morning. I made trips to all the towing places and police stations, all the time thinking that it was towed by cops .By around 10 a.m., the cops decided that it was actually stolen. After filing a report with them, I finally got to work thinking how my day was completely messed up. Later in the day I went to pick up a rental car at Enterprise only to realize that my license was missing, too, along with my car. I told the enterprise guy the whole story and he offered to take me to the closest DMV and get a duplicate license. 1 was totally shocked. I did not know why this complete stranger would want to take some time off his day to help me. He actually took me to DMV, got a duplicate and then rented me a car. I was upset the whole day because of the events happening to me but somehow this simple act of kindness from a complete stranger made it all worth it. It cheered me up and made me forget all the troubles of the day. I was so moved by this kind act that the next day I made sure someone else got a similar surprise. I took some smiley shaped chocolates and left them on some of my colleagues' desks. There is still a lot of goodness out there in the world. We just need to take the time to notice it. I hope that this story would inspire many others like me to do more acts of kindness. Question: We can infer that DMV is _ . Options: A: an office for license B: a towing place C: a renting place D: a parking lot

Traditional economics says that people are rational beings who will lie if it's to their advantage. A recent university study has shown that, actually, we're pretty honest --especially when we're at home. Researchers in Germany phoned people at home and asked them to toss a coin. There was a strong financial incentive to fake the result: if the coin landed tails-up, the participants would receive money or a gift ticket, while if the coin landed heads-up, they would get nothing. Because they were on the phone, they knew there was no risk of getting caught if they lied. And yet people told the truth.Over hundreds of tosses, a coin will land tails-up roughly 50% of the time. In this study 0ver half the people asked (55.6%) said that the coin landed heads-up, which meant they would receive nothing. Previous studies had found that people were more dishonest. In those laboratory studies, 75% of people reported a winning coin and claimed a reward. So the research team thinks it's being in our own homes which makes us play fair, although it's not yet clear why. In fact both types of study show people are surprisingly reliable. Even in the laboratory, 25% of people turned down a reward by telling the truth. The researchers say this is because honesty is highly valued in human society.We care about our reputation and our sense of ourselves as respectable people. So lying has a psychological cost and it seems this cost is more important than the financialbenefits of lying . Question: When do people lie according to troditional economics? Options: A: When they are at home B: When it's to their advantage . C: When they would receive nothing D: When it comes to financial benefits.
