PROBLEM: 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

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

PROBLEM: Article: Mother managed to buy me some more paint brushes, along with one or two drawing books and a pencil. This, of course, broadened my range of expression and allowed me to have a greater choice of subjects. After the first few weeks of uncertainty and awkwardness, I settled down contentedly with my new pastime. I painted every day upstairs in the back bedroom, completely by myself. I was changing. I didn't know it then, but I had found a way to be happy again and to forget some of the things that had made me unhappy. Above all I learned to forget myself. I didn't miss going out with my brothers, for I had something to keep my mind active, something to make each day a thing to look forward to. I would sit on the floor for hours, holding the brush between my toes, my right leg curled up under my left, my arms held tightly at my sides, hands clenched. All my paint and brushes were around me, and I would get Mother or Father to pin the drawing paper to the floor with tacks to keep it keep it steady. It looked like a very awkward position, with my head almost between my knees and my back crooked, but I painted all my best pictures this way, with the wooden floor as my only easel . Slowly I began to recover from my earlier depression. I had a feeling of pure joy while I painted, a feeling I had never experienced before and which seemed almost to lift me above myself.
