Question: Read the following article and select the best answer. Article: I'd just got in a taxi at the railway station when suddenly I found one of my suitcases missing. Just then, I saw a young fellow about 30 walking away with it, opening it and drawing out the valuables. "Stop thief! Stop thief!" I shouted and threw open the car door and rushed out to him, followed by the driver and half a dozen passers-by. Very soon the thief was cornered at the turn of the road. My driver caught the thief by the neck and put his hand into his trouser pocket, drawing out money, credit card, telephone book and so on and put them back into my suitcase. Half an hour later, the car was running at full speed on the express highway. I sat back and breathed a long sigh of relief . But as I pulled out those stolen things from the suitcase and started to check them, I became dumbfounded . Before my eyes were 200 yuan instead of 100. And a blood test report of a 58-year-old woman appeared. I suddenly realized that the taxi driver must have mistaken the thief's belongs and put his into my suitcase. The pitiful and begging look of the poor young man flashed across my mind again. My heart began to sink. Two years has passed since then. But this event keeps coming back to me. Was the young man a habitual robber or a dutiful son who had been driven to desperation to find money to save his mother's life? My heart aches for him. How I wish I had gone back that summer afternoon to return the 200 yuan and say sorry to him. For the first time in my life, I realized that hate and love are very close.

Question: Read the following article and select the best answer. Article: Dickson Despommier, a public health professor at Columbia University in New York City developed an idea with his students nine years ago. They imagined people in cities growing crops inside a tall building. Tomatoes could grow on one floor of the skyscraper , potatoes on the next, small animals and fish on the floor above. This vertical farm, or "farmscraper", could have space for restaurants and other places that serve food, like schools or hospitals. They could serve foods that are truly locally grown. But why would anyone want to build a farm indoors in a city? Dickson Despommier believes it will become necessary. The world needs to find places to produce enough food to feed the growing population. Space, he says, is an all-important issue. The professor also points to the problems of traditional farms. They use a lot of freshwater. Their fertilizer and animal waste can pollute water resources. And their growing seasons can be limited. But inside the vertical farm, crops could grow all year. And there would be no wind to blow away soil. Farmers would not have to worry about too much or too little rain, or about hot summers, freezing winters or insects. And without insects there would be no need for chemicals to kill them. Farm machines that .use fossil fuels, like tractors, would not be needed either. And water could be recycled for drinking. "The vertical farm reuses everything, so there is no waste," says Professor Despommier. Even buildings could be saved. Old buildings could become new farms and provide jobs. The professor has been actively proposing the idea to cities as far away as Dubai and Canada. But so far it exists only in plans and drawings, and a model at the Museum of Science and Industry in Chicago. Critics say building a farmscraper would cost too much, especially considering the price of land in many cities. Dickson Despommier estimates the cost at about twenty to thirty million dollars. But he says the building would not have to be very tall. And his graduate students have found many... Question: According to the passage the purpose of proposing the idea of a farm scraper is to _ - find places to produce enough food - serve food that are truly locally grown - prevent polluting the limited land - save fresh water
Answer: find places to produce enough food
