It's one way to reduce human effect on the planet.Eating local means to try to buy and consume foods that are grown in places close to home.However, most of the food sold at supermarkets is not locally grown or produced.Trucks and planes deliver these foods from hundreds or thousands of miles away.During the transportation, greenhouse gases are produced, causing global warming.So the shorter the distance your foods must travel, the less the harm is done to the environment. But how do you get local food if you live in a large city, hundreds of miles away from farms?Environmental health scientist Dickson Despommier and his students came up with the idea of a "vertical farm". A vertical farm is a glass-walled structure that could be built as tall as a skyscraper.Since the garden is built upwards, rather than outwards, it requires much less space than an ordinary farm.The world is quickly running out of room for ordinary farming.Vertical farms could be a key to this situation.Despommier imagines a 30-story building with a greenhouse on every floor.The walls of the building would be clear, to allow crops to get as much sunlight as possible.Depending on a city's water resources, Despommier thinks hydroponic farming is another method for the vertical farm which needs no soil to grow plants. Despommier says the hydroponic greenhouses would use a system that would use a city's waste water and fill it with nutrition to make the crops grow.If this method works, it would provide food to a city and save millions of tons of water. The idea of a vertical farm has attracted the attention of government officials around the world.Scott Stringer, a government official from New York City, thinks the city is suitable for the vertical farming."Obviously we don't have much land left for us," Stringer said, "But the sky is the limit in Manhattan." Despommier admits that there is still a lot of work to do to make vertical farms a reality."But I think vertical farming is an idea that can work in a big way." he says. Question: Why are people advised to eat local? - Because it means convenience to people. - Because it can help people save a lot of money. - Because local food has more nutrition. - Because it is environmentally friendly.
Because it is environmentally friendly.

Read the following article and select the best answer. Article: I was saved from sin when I was going on thirteen. But not really saved. It happened like this. There was a big revival at my Auntie Reed's church. Then just before the revival ended, they held a special meeting for children, "to bring the young lambs to the fold ". My aunt spoke of it for days ahead. That night I was accompanied to the front row and placed on the mourners' bench with all the other young sinners, who had not yet been brought to Jesus. My aunt told me that when you were saved you saw a light, and something happened to you inside! And Jesus came into your life! And God was with you from then on! She said you could see and hear and feel Jesus in your soul. I believed her. So I sat there calmly in the hot, crowded church, waiting for Jesus to come to me. I wanted to see him, but nothing happened to me. Nothing! I wanted something to happen to me, but nothing happened. Now it was really getting late. So I decided that maybe to save further trouble, I'd better lie and say that Jesus had come, and get up and be saved. So I get up. The whole room broke into a sea of shouting and my aunt threw her arms around me. The minister took me by the hand and led me to the platform. That night I cried. I cried, in bed alone, and couldn't stop. My aunt woke up and told my uncle I was crying because the Holy Ghost had come into my life, and because I had seen Jesus. But I was really crying because I couldn't bear to tell her that I had lied, that I had deceived everyone in the church, that I hadn't seen Jesus, and that now I didn't believe there was a Jesus any more, since he didn't come to help me. Question: What do we know about the writer's aunt? - She was a liar - She pretended to believe in God - She believed the existence of Jesus - She could see God with her own eyes
She believed the existence of Jesus

Read the following article and select the best answer. Article: When I stepped out the plane from Miami into Charlotte, North Carolina, airport for a connecting flight home, I immediately knew something was wrong. Lots of desperate people crowded the terminal. I quickly learned that flights headed to the Northeast were called off because of a storm. The earliest they could get us out of Charlotte was Tuesday. It was Friday. A gate agent stood on the counter and shouted, "Don't ask us for help! We cannot help you!" I joined a crowd that ran from terminal to terminal in search of a flight out. Eventually, I found six strangers willing to rent a van with me. We drove through the night to Washington, where I took a train the rest of the way to Providence. The real problem, of course, is that incidents like this happen every day, to everyone who flies, more and more often. It really gets to me, though, because for eight years I was on the other side, as a flight attendant for Trans-World Airlines (TWA). I know the days are gone when attendants could be written up if we did not put the lines napkins with the TWA logo in the lower right-hand corner of the first-class diners' trays. As are the days when there were three dinner options on flights from Boston to Los Angeles in economy class. When, once, stuck on a tarmac in Newark for four hours, a planeload of passengers got McDonald's hamburgers and fries by thoughtfulness of the airline. I have experienced the decline of service along with the rest of the flying public. But I believe everything will change little by little, because I remember the days when to fly was to soar . The airlines, and their employees, took pride in how their passengers were treated. And I think the days are sure to come back one day in the near future. Question: How did the writer get to Providence at last? _ - by air - by van - by train - by underground
by train
