Some young engineers from the United States have brought the Internet to several areas of rural Kenya. Their idea was to connect the communities to the Web by satellite. But there was a problem—the areas are not even connected to Kenya’s electric power supply. However, the young engineers offered the answer: solar panels. Energy from the sun powers the satellite dishes and computers that link the areas with the world outside. Kelly Moran, Joan Ervin and Tricia Donajkowski spent ten days in Kenya in November. The three women recently earned master’s degrees in space systems engineering from the University of Michigan. People now have access to educational, medical and all kinds of other information. Farmers, for example, can easily find weather, crop and price information online. The project began back at the college of engineering in Ann Arbor, Michigan in 2007. That was when 25 students in a class taught by Thomas Zurbuchen first talked about the idea. The goal was to test whether Internet stations could be set up, how much they would cost, and how long they could operate. But the engineers also had to consider other things such as social needs. Students from the public health and business schools offered advice. The young engineers also had to design the equipment to survive the heat in Africa. Prof. Zurbuchen praised his former students for "making something work in a different climate far away from home." Just 5% of Africans have Internet connections. The International Telecommunication Union says 1/3 of Kenyans have mobile phones. But mobile phones may or may not work well with the Internet.
23. What was the solution to the connection to Kenya’s Internet?
24. What is the advantage of connecting the communities to the Web?
25. Why did Prof. Zurbuchen speak highly of the young engineers?

选项 A、Providing electric power to the satellite dishes and computers.
B、Providing solar power to the satellite dishes and computers.
C、Providing advanced satellite dishes to connect the Internet.
D、Providing computer technology to connect the Internet.

答案B

解析 事实细节题。短文中提到,通过卫星为肯尼亚地区连通网络存在的一个问题是这些地区与肯尼亚电力供应系统之间没有连接。工程师的解决方法是使用太阳能电池板,因为太阳能为卫星接收器和电脑提供能量,从而将这些地区与外界联系起来。
