It's reported that a Nepali teenager has designed a $32 solar panel using human hair. Milan Karki,who is 18 years old and lives in a village in rural Nepal,used human hair to replace silicon ,which is a common but expensive componet of solar panels. By using hair as a replacement,Karki says that solar panels can be produced for around $32,a price that could be halved if they were mass-produced. The solar panel works,because melanin ,which gives hair its colour,is light sensitive and can act as an elecrtical conductor.Kaiki was inspired to think of the idea by a Stephen Hawking book ,which explained how to create elecrtic energy from hair. The device that Karki has invented is capable of producing 9V or 18V of energy--plenty to charge a mobile phone. "Half a kilo of hair can be bought for only 16p in Nepal and lasts a few months;whereas a pack of batteries would cost50p and lasts few nights,"according to The Daily Mail. The solar panel is claimed to be easy to service as the hair is easy to replace. Karki has now seng out several devices to other disrticts near his home for tetimg .He said,"First I wanted to provide elecricity for my home,then my village .Now I am thinking for the whole worle." So next time when you have a haircut,do remember to keep your hair cut down to use for energy.Perhaps you can also provide elecrticity for your home,even your village using your own hair.

Q: Write a multi-choice question for the following article, with the given choices and answer: Article: Arabs consider it extremely bad manners to start talking business immediately. Even the busiest government official always takes extra time to be polite and offer refreshments . No matter how busy you are, you should make time for this. The conference visit is a way of doing business throughout the Arab world. Frequently, you will have to discuss your business in the presence of strangers, who may or may not have anything to do with your business. Do not be surprised if your meeting is interrupted several times by people who come into the room unannounced, whisper, or speak softly to the person with whom you are talking, and leave. Act as though you do not hear, and never show displeasure at being interrupted. Making decisions quickly is not an Arab custom. There is a vagueness in doing business in the Middle East which will puzzle a newcomer. Give yourself lots of time and ask lots of questions. When an Arab says "yes", he may mean "maybe". When he says "maybe", he probably means "no". You will seldom get a direct "no" from an Arab because it is considered not polite. Instead of "no", he will say "inshallah", which means "if God is willing". On the other hand, "yes" does not necessarily mean "yes". A smile and a slow nod might be like an agreement but in fact your host is being polite. An Arab considers it rude to disagree with a guest. Options: A why you need extra time when you visit Arab countries B how to be polite when doing business in the Arab world C why Arab officials are so busy D what Arabs say when doing business Answer: B how to be polite when doing business in the Arab world Question:
