     When you have a question about something, where do you go? For many people the answer is simple as

they can go online to a search engine like Google or Yahoo. But what about people in rural or underdeveloped

areas who may have no way to get on the Internet?

     A business and international development professor in California, Rose Shuman, found an answer for them:

Question Box. Question Box is a service that provides answers-free of charge-for people who cannot search

the Internet directly. The users of Questions Box might be those who might not be able to read, or simply have

no access to the Internet.

     Question Box began three years ago in India. People used a metal call box with a push-to-talk button to

connect a live operator. Rose Schuman explained," You just need to push a big green button on the box which

will connect you directly to our operators who are sitting in front of computers, and speak your language. You

can ask them any sort of question you want, and they'll look it up in English or in Hindi, or whatever the main

language is, and translate the answer back for you."

     The service is currently offered in two villages. The latest version of the box uses mobile phone technology, and solar panels in case the electrical power fails. Rose Shuman says the aim was to make the box as easy as

possible for users,"It is very efficient (效率高的). Rather than try to bring a lot of difficulties to them and

expect them to spend a lot of time to learn how to use the Internet, the idea was to make a technology tha

t even Grandma could use."

     In April 2009, Question Box was introduced to Uganda. Forty community workers with mobile phones

connected villagers to call center operators in Kampala. The community workers went around telling people

about the service. They wore T-shirts that said"Ask me." But Internet service in Uganda proved slow and

undependable. So Question Box teamed up with a local technology company to store information on a local

server. That way, the researchers in Kampala could quickly search the database for answers.
