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! How did the volunteers react when smelling something nice and hearing musical notes? A) They took a deep breath. B) They had a wonderful dream. C) They woke up at once. D) They took a short breath.

Sunny countries are often poor. A shame, then, that solar power is still quite expensive. Eight19, a British company by Cambridge University, has, however, invented a novel way to _ this. In return for a deposit of around $10 it is supplying poor Kenyan families with a solar cell able to generate 2.5 watts of electricity, a battery that can deliver a three amp current to store this electricity, and a lamp whose bulb is a light-emitting diode . The firm thinks that this system, once the battery is fully charged, is enough to light two small rooms and to power a mobile-phone charger for seven hours. Then, next day, it can be put outside and charged back up again. The trick is that, to be able to use the electricity, the system's keeper must buy a scratch card--for as little as a dollar--on which is printed a reference number. The keeper sends this reference, plus the serial number of the household solar unit, by SMS to Eight19. The company's server will respond automatically with an access code to the unit. Users may consider that they are paying an hourly rate for their electricity. In fact, they are paying off the cost of the unit. After buying around $80 worth of scratch cards--which Eight19 expects would take the average family around 18 months--the user will own it. He will then have the option of continuing to use it for nothing, or of trading it in for a bigger one, perhaps driven by a 10-watt solar cell. In that case, he would go then through the same process again, paying off the additional cost of the upgraded kit at a slightly higher rate. Users would therefore increase their electricity supply steadily and affordably. According to Eight19's figures, this looks like a good deal for customers. The firm believes the average energy-starved Kenyan spends around $10 a month on oil--enough to fuel a couple of smoky lamps--plus $2 on charging his mobile phone in the market-place. Regular users of one of Eight19's basic solar units will spend around half that, before owning it completely. Meanwhile, as the... What might be the most suitable title for the passage? A) Solar Energy: Starting from Scratch. B) Eight19: a creative British Company. C) Kenyan Families: Using Solar Energy for Free. D) Poor Countries: Beginning to Use Solar Energy.
