input question: Write a multi-choice question for the following article: Article: A Nepalese teenager had made a PS 23 solar panel ( ) using human hair. Milan Karki, who is 18 years old and lives in a village, used human hair to replace silicon, which is a common but expensive part of solar panels. By using hair as a replacement, Karki says that solar panels can be produced for around PS 23. Karki got the idea from a Stephen Hawking book, which explained how to create energy from hair. The device that Karki has showed can produce 18w of energy -- plenty to _ a mobile phone. "Half a kilo of hair can be bought for only 16p in Nepal and last a few months; but a pack of batteries would cost 50p and last a few nights," according to The Daily Mail. The solar panel is easy to service as the hair is easy to replace. Karki has now sent out several devices to other places near his home for testing. He said, "First I wanted to provide energy for my home, then my village. Now I am thinking for the whole world."???

Ye Jingying, a sleep expert at Beijing Tongren Hospital, says: "If people often wake up during the night, or always feel weak and tired in the day, they should pay attention to their sleep pattern ." Many people play with their cell phones or iPads before sleeping. The report said that this is one of the main reasons for bad sleep. Other reasons include stress and bad moods. How to sleep well? Above all, get enough sleep. Seven to nine hours of sleep every night is perfect for an adult, and eight to nine hours is best for a teenager. Forming good sleep habits is important. The report suggested that people need to keep away from digital devices for at least an hour before sleep. The lights keep their brains excited for a long while.
