Article: When you hear the word "farm", chances are you picture rolling hills in the country covered with cows and cornstalks. Some scientists, engineers and city planners say the farms of the future could rise straight into the air---in skyscrapers in the world's most populated cities. It might sound far--fetched, but in fact, some of the technology for growing crops indoors already exists. The scientists at the South Pole research station enjoy fresh salads every day from vegetables they grow in their own greenhouse. And NASA has been experimenting for years with methods for growing fresh fruits on the moon or even on Mars. As is known, traditional farming takes a plot of land as big as the entire state of Virginia just to grow enough food for 8 million people, says ecologist Dichson Despommer. Cities that can't grow their own food are often influenced by disasters such as hurricanes that can make it impossible for trucks to deliver fresh produce to grocery stores. In addition, fruit and vegetables grown outdoors face all kinds of dangers, from flooding to insect pests to weather instability, such as late or early frosts that can damage a crop. "You can control everything indoors. You can't control anything outdoors," Despommier says. To top it off, by the year 2050, the world population will grow by another 3 billion. "Where will we grow the food for all these people?" Vertical farming----growing crops in skyscrapers, tens of stories high----is the answer," says Despommier. Others say _ could provide new uses for hundreds of abandoned buildings in cities around the world. Crop waste, like leaves, would be composted , and the gases given off from composting would be used to heat the building. "I'd say it is going to be tough," says agriculturist Giacomelli. It can be tricky to regulate climate conditions indoors. Plus, plants differ in their weather and lighting requirements. Tomatoes like warm, sunny weather, while greens like lettuce prefer cooler temperatures. And nearly all crop plants require... Question: What attitude does Giacomelli have towards the vertical farming? Yes or no, is the answer "Uncertain"?
No

Q: Article: Music notes fly through my ears. Soft sounds float in the air, as if they are floating on water. Music is like a paintbrush, painting sounds in the sky. A warm sun shining bright, clouds drifting far away in the night, to the sounds of music. Music is nature's friend, as one paints our earth, and the other fills our hearts. Question: The writer associates music with the following EXCEPT _ . Yes or no, is the answer "a person who plays music"?
A: No

Question: Article: Complete silence is found only in laboratories called anechoic rooms. The walls and ceilings, made of blocks of special sound-sucking materials, are more than three feet thick, while floor coverings are six-foot layers of feathers or cotton wool. Silence here can be as painful to the ears as the din(continuous loud noise) of a steelworks or a rocket blast-off, yet scientists get used to this and stay in these silent rooms for hours at a time, using microphones and electronic equipment to test the various materials being developed to make the world a less noisy place. Architects have used scientific discoveries to solve noise problem in a number of ways. Walls are hollowed (having empty space inside) and then filled with sound-sucking materials similar to cotton wool. Extra-thick carpets cover the floors, and thick woolen curtains cover the windows. Air conditioning and heating channels are made less noisy by having the air passing through hundreds of tiny holes in baffles made of sheets of soundsucking materials. Unfortunately, these techniques and others often work too well in some buildings. Noise-proof rooms become almost anechoic and people living in them are disturbed by the lack of sound. One way of handling this problem is to use what they call "sound perfume"--artificial (similarly produced, made by man) noise is piped to rooms through small loudspeakers. Question: The writer implies that _ . Yes or no, is the answer "performing experiments in anechoic rooms can be a frightening experience"?
Answer: No

Article: One period of our lives when better results are demanded of us is, strangely enough, childhood. Despite being young we are expected to achieve good grades, stay out of trouble, make friends at school, do well on tests, perform chores at home and so on. It's not easy. Likeable children enjoy many advantages, including the ability to deal more easily with stresses of growing up.In her bookUnderstanding Child Stress, Dr. Carolyn Leonard states that children who are likeable and optimistic are able to gain support from others. This leads to focus and resilience , the ability to recover from or adjust early to life stress. Much research shows that resilience has enabled children to succeed in school, avoid drug abuse, and develop a healthy self-awareness . Why does a likeable child more easily handle stress and do better in his or her life? Because likeability helps create what's known as a positive feedback loop . The positive feelings you want to see in other people are returned to you, creating constant encouragement and motivation to deal with the daily stress of life. This feedback loop continues into adulthood. To return once again to the example of teaching, learning becomes easier with a likeable personality. Michael Delucchi of the University of Hawaii reviewed dozens of studies to determine if likeable teachers received good ratings because of their likeability or because they in fact taught well. Delucchi found that "Students who perceive a teacher as likeable, in contrast to those who do not, may be more attentive to the information that the teacher delivers and they'll work harder on assignments, and they will learn more." You may have noticed this pattern in your own life when you try to give some advice. The more positive your relationship with that person, the more he or she seems to listen, and the more you feel certain that that person has heard you and intends to act on your words. Question: According to Dr. Leonard, likeable children _ . Yes or no, is the answer "can achieve more and understand themselves better"?
No
