Article: Farming is moving indoors, where the sun never shines, where rainfall is irrelevant and where the climate is always right. The perfect crop field could be inside a windowless building with controlled light, temperature, wetness, air quality and nutrition. It could be in a New York high-rise or a sprawling complex in the Saudi desert. It may be an answer to the world's food problems. The world is already having trouble feeding itself. Half the people on Earth live in cities, and nearly half of those--about 3 billion--are hungry or ill-fed. Food prices, currently increasing, are _ by dryness, floods and the cost of energy required to plant, harvest and transport. And prices will only get more unstable. Climate change makes long-term crop planning uncertain. Farmers in many parts of the world are already using water available to the last drop. And the world is getting more crowded: by mid-century, the global population will grow from 6. 8 billion to 9 billion. To feed so many people may require expanding farmland at the expense of forests and wilderness, or finding ways to completely increase crop output. Gertjan Meeuws has taken the concept of a greenhouse a step further, growing vegetables and house plants in enclosed and regulated environments. In their research station, water flows into the pans when needed, and the temperature is kept constant. Lights go on and off, creating similar day and night, but according to the rhythm of the plant. A building of 100 square meters and 14 layers of plants could provide a daily diet of 200 grams of fresh fruit and vegetables to the entire population of Den Bosch, about 140, 000 people. Their idea is not to grow foods that require much space, like corn or potatoes. Here sunlight is not only unnecessary but can be harmful. Plants need only specific wavelengths of light to grow. Their growth rate is three times faster than under greenhouse conditions. They use about 90 percent less water than outdoors agriculture. And city farming means producing food near the consumer, and there's no need to transport it long distances.
Question: It can be inferred from the text that Gertjan Meeuws's farming _ .
Options: (A) helps save sea water a lot (B) suits different conditions (C) is completely different from greenhouse agriculture (D) suits the production of corn
Asnwer: B
answer:
Yes

Article: An annoying problem for humans, who like to boast about all the distant planets and moons we have explored, is that we've never taken a good look right under our noses. The inside of the earth is relatively close, but how can we get there? The deepest oil well enters a mere six miles into the crust (the center of the earth is about 4,000 miles deeper). Russian scientists dug the deepest hole in Siberia, but bottomed out at about 7.5 miles below the surface. The Mohole project, a U.S. plan in the 1950s, called for drilling a hole 25 miles down to the boundary between the hard rocks of the crust and the soft mantle . Sadly the project involved government supporting. It gets harder and harder to drill deep into the earth because rocks get softer and softer. Hard but easily broken at the surface, rocks become plastic at depth, and the pressure caused by the weight of the overlaying crust --- about 52,800 pounds per square inch at a depth of ten miles, makes further drilling impossible. What little we know about the inside of the earth (like the fact that there's a crust, a mantle, and a core) comes from indirect evidence, such as the analysis of earthquakes. So maybe it's time for a thorough new method to explore the earth's inside. Scientist David Stevenson says we should forget about drilling holes. Instead, we should open a crack . Stevenson suggests digging a crack about a half mile long, a yard wide, and a half mile deep (not with a shovel) but with an explosion on the scale of a nuclear bomb. Next, he'd pour a few hundred thousand tons of molten iron into the crack, along with a robot. The iron, thicker than the surrounding crust, would move downward at about 16 feet per second, carrying the robot with it and opening the crack deeper and deeper. The iron mass would drop for about a week and 2,000 miles to the outer edge of the earth core, the robot sending out data to the surface. Stevenson compares his idea to space exploration. "We're going somewhere we haven't been before,"he says. "In all possibility, there will be surprises." This idea can probably be put in the drawer marked with Isn't Going To Happen. The robot would have to survive temperatures that would melt pretty much anything. But Stevenson's idea may inspire a new look at an old problem. Great things can come from what seems like impossible ideas.

Article: When Kathryn was 6 years old, she sat outside for three hours at her home and did not make a sound.Her parents wondered why she was so quiet, only to discover that she was drawing a picture of a flag outside. She recalled. "That's what I wanted to do that day," said Kathryn, who is now 23 years old. And in the future, she continued to do art as a hobby. Recently, Kathryn was named Lake Placid's first artist in the neighborhood. She will be there for at least four weeks and possibly more. During that time, she will teach an art class and focus on her own art. Much of her work includes creating photos. She said: "There is always something there that you haven't included, so you can never stop when painting a photo." Kathryn ended up as the first artist just by chance. She said her sister was on vacation in Florida and looking for a job in Lake Placid. The sister got the job and moved there. Kathryn said she visited her sister and was ordered to do wall paintings inside a building. Later, her sister saw a demand for an artist on line and suggested she should apply. Kathryn said she's the first artist in her family, but added that her parents are creative. Her father loves to create things from wood, she said. "Anything you can make out of wood, he has made it," she said. Her own creativity with art continued through college. While at college, she was once employed to recreate a photo of a couple on a vacation to Florida and one of a sunset in either North Carolina or South Carolina. Kathryn said she's looking at other forms of art. The time she spends here will help her to "figure out who I am as an artist," she said.
Question: While painting a photo, Kathryn thinks _ .
Options: (A) It's hard to finish a perfect job. (B) you can't stop half way (C) you may miss the photos somewhere (D) you have to finish it at a time
Asnwer: D
answer:
No
