Article: In recent years, the black bear population in the US has risen. Forests once cleared for farming have started to grow back and black bears have returned to them. But the bears are finding that their forest habitat has changed. Instead of thick forests covering thousands of acres, bears now have neighbors nearby. Roads, homes, schools, and shopping centers have been built at the edge of their forest home. And with humans and bears trying to share the same space, problems arise. Black bears usually prefer to avoid people, but their nose may lead them into trouble. Their normal diet includes nuts, insects, and plants. But given the opportunity, they will gladly help themselves to whatever they can find. With the great sense of smell, the bears can _ a tasty treat 2 or 3 miles away. Food left out in a park or backyard is an invitation to dinner. And whileraiding a cooler, bird feeder , trash can, car, or even a home, they can do a lot of damage. When that happens, people get angry. If another solution doesn't immediately appear, they often want the bears killed. Bear Aware, Bear Wise, and Bear Smart are trying to keep that from happening. They want people to respect bears, not fear them, and are suggesting ways to reduce the chances of bears stopping by for a snack. They're convincing people that by following some simple steps, it's possible to live peacefully with our wild neighbors. Question: We learn from the text that black bears _ . Yes or no, is the answer "eat different foods"?
No

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 passage suggests that _ . Yes or no, is the answer "loudspeakers are as important as sound-proofing materials"?
No

Article: As a nation we are becoming more aware of the food we and our children are eating.The recent campaign to improve school dinners by celebrity chef Jamie Oliver has helped raise awareness of our fast food lifestyles.While we may be trying to eat more healthily,it seems we still have some bad habits. *Healthy eaters or just trendy?

"We enjoy eating out a couple of times every month whether with friends or just as a couple.We like trying new things so we go to different restaurants." said Craig,25,County Durham. *Eating on the go From chocolate bars to sandwiches more people are eating on the go--on the street,in cars or on buses and trains.While our parents and grandparents may frown at this behaviour,considering it to be bad manners,people eat on the go because they are rushing from one place to another.And in the home the number of people sitting down at a dining table for their evening meal is on the decrease as meal times become more informal. "If I'm running late for work I don't think twice about eating toast in the car or on the bus but I know my mum wouldn't approve," said Stacey,24. Question: What can we infer from the text? Yes or no, is the answer "We should get rid of the bad habits and try to be healthier."?

Article: Governments and health officials around the world continued to take steps Tuesday against the outbreak of swine flu that has killed scores of people in Mexico and spread to the U.S., Europe and possibly Asia. By early Tuesday, the swine flu outbreak in Mexico had caused in 152 deaths and more than 1,600 illnesses. So far, at least 113 cases have been proved worldwide, including 64 in the United States; six in Canada; 11 in New Zealand and two each in Spain the United Kingdom and Israel. None has yet resulted in death. The World Health Organization on Monday raised its alert level from three to four on its six-level scale. The move means the U.N. agency has determined that the virus can transmit from human to human. "In this age of global travel, where people move around in airplanes so quickly, there is no region to which this virus could not spread," said Fukuda, assistant director-general of the WHO. Governments around the world struggled to prevent further outbreak. Some, like China and Russia, banned pork imports from the United States and Mexico. U.S. President Barack Obama said the outbreak was a cause for concern, not for alarm. The government urged travelers to avoid non-essential travel to Mexico. The latest WHO report listed only seven proved swine flu deaths in Mexico but it was not clear why there was the discrepency. Mexico City has closed all schools until at least May 6 to help curb(control) the spread of swine flu and ordered 35,00 public venues to close or serve only takeaway meals. In addition, bars, clubs, movie theaters, pool halls, gyms, sport centers and convention halls have been told to close until May 5. Armed police officers are also guarding hospitals in Mexico City while roads and schools in the city of 20 million people are deserted. Officials also have talked about shutting down the bus and subway systems. Question: Fukuda's words suggest that _ . Yes or no, is the answer "this virus can spread quickly because of global travel"?
No
