Input: Consider Input: Article: Scientists have proved that sleeping and learning go hand in hand. Even a short nap can boost our memory and sharpen our thinking. But the relationship goes deeper than that. "The brain is not passive while you sleep," scientist Anat Arzi said. "It's quite active. You can do many things while you are asleep." Arzi and her coworkers didn't try to teach the sleeping volunteers any complex information, like new words or facts. Instead, the scientists taught volunteers to make new connections between smells and sounds. When we smell something good, like a flower, we take deep breaths. When we smell something bad, we take short breaths. Arzi and her co-workers based their experiment on these reactions. Once the volunteers fell asleep in the lab, the scientists went to work. They gave them a whiff of something pleasant and meanwhile played a particular musical note. They didn't wake up, but they heard--and sniffed deeply. Then the scientists gave the volunteers a whiff of something terrible and played a different musical note. Again, the volunteers heard and smelled--a short snort this time--but didn't wake up. The researchers repeated the experiment. After just four repetitions, volunteers made a connection between the musical notes and their paired smells. When the scientists played the musical tone that went with good smells, the sleepers breathed deeply. And when the scientists played the musical tone that went with bad smells, the sleepers breathed briefly--despite there being no bad smell. The next day, the volunteers woke up with the sound-smell connection. They breathed deeply when hearing one tone and cut their breaths short when hearing the other, which must have been unusual for them. Imagine walking down the street and taking a deep breath upon hearing a particular sound!
Answer: to make sound-smell connections

Output: In the study, the volunteers were taught _ .

Input: Consider Input: Article: The U.S. government may issue stronger regulations about the use of tobacco. Many governments and private buildings have "No Smoking" regulations. In airplanes, on trains and at cinemas, Golf courses are seriously thinking of keeping out smokers, so are schools, shopping malls and even football fields. So where do people go to fill their lungs with nicotine? The government is working on it. One suggestion is that the government set aside a piece of land somewhere in the United States where smokers could go when they want a cigarette. Yellow Stone Park has been in the list, but many people don't agree because they fear that second-hand smoking would make the bears there sick. The Mojave Desert in California is also being studied, and so are Las Vegas Casinos . The smokers were not too nervous about the government idea. They say they are not going to California just to light up. They have a right to smoke at home. To make life more pleasure for those who find it hard to give up smoking, the government is seriously thinking of getting somewhere for the smokers. The tobacco companies are fighting the idea like mad. They say nobody has proved that cigarettes are bad for you. They say as a matter of fact, the doctors have proved that a cigarette saved a person's life after that person was shot. Other places under consideration are: the cold areas in Alaska, the Rocky Mountain in Colorado and the Whitewater River in Arkansas.
Answer: are not so free

Output: Smokers in the U.S. _ to light a cigarette now.

Input: Consider Input: Article: One afternoon last week, I saw three tearful children from my son's school being comforted by teachers. That morning, my 11-year-old had stomach pains, retching into a bowl. Talking to other mothers later, I heard about other children with stomachache or difficult sleeping the night before. What caused so much pain? Sports day. Sports day might be necessary at a highly-competitive independent school, but not at a village primary school. For the children who can fly like the wind, sports day cause no problem. For those who are overweight or just not good at sport, it is nightmare . Even for those who enjoy running but fall halfway down the track in front of the entire school and their parents, it can prove a disease. Why do we put our children through this annual suffering? Some may say competition is character building; or it's taking part, not winning, that's important; or that's a tradition of school life. I just felt great pity for those children in tears or in pain. Team games at the end of sports day produced some close races, wild enthusiasm, lots of shouting -- and were fun to watch. More importantly, the children who were not so fast or quick at passing the ball were hidden a little from everyone's eyes. Some of them also had the thrill of being on the winning side. I wish that sports day could be abandoned and replaced with some other less competitive event. Perhaps an afternoon of team games, with a few races for those who want them, would be less stressful for the children and a lot more fun to watch.
Answer: it is a tradition of the school
Output: Sports day is still an annul event in this school probably because _ .
