TASK DEFINITION: In this task, you're given an article and an answer. Your task is to generate the question for the answer based on the given article.
PROBLEM: Article: A window is more than just an opening that you can see through. It can affect the way a building looks,how much energy a building USES and even how you feel. Scientists are now working on ncw technologies to create"smart windows". Unlike normal windows,high-tech smart windows can change from clear to dark and back again with the touch of a button --or even automatically as the outside light changes. Smart windows have the power to make the world a cleaner and more comfortable place. Instead of turning on air conditioners ,people could simply _ the windows in a building's empty rooms. With the rooms less bright,they would stay cool,and people would save energy and money at the same time. That's why smart windows are so exciting. Says Claes Granqvist. He's a professor of physics at Uppsala University in Sweden. If you think that you don't care much about windows,you should think again,Granqvist says. Most people who live in developed countries spend about 90% of their time inside buildings and cars. You might spend even more time than that indoors during the winter if you live in a cold climate. Imagine then what it would be like if there were no windows. You'd have no idea what's going on outside. So,the light of the nature is important for improving the way people feel when they stay indoors. The development of smart windows could mean that a lot of air-conditioning systems may no longer be needed. "In the future," Granqvist says "our buildings may look different."
Answer: They can change automatically or by pressing a button.

SOLUTION: About the smart windows.which of the following is NOT true?

PROBLEM: Article: International Robotics Forum Tokyo Big Sight,Tokyo, Japan, December 4-5 The Robotics Society of Japan (RSJ), to provide opportunities for young robot lovers to learn more about industrial and service robots, is going to hold the International Robotics Forum that will cooperate with this year's International Robot Exhibition. The lectures and explanations throughout the Conference will be given in Japanese but will be interpreted into English at the same time. The Conference will offer a great opportunity for senior high school students from all around the world to communicate with each other through robots. Therefore, we look forward to your active participation. The event will take place two days. On the morning of Day One, Prof. Shinichi Yuta of the Shibaura Institute of Technology will give a lecture on basic mobile robotics and learning through robots. This will be followed by a talk by Mr. Kazuhiko Yokoyama of Yasukawa Electric Corporation who will explain the mechanism and control of robots and also point out the highlights of the International Robot Exhibition. We will prepare a challenge for all the participants. We will send you themes for robot research. You will study them in advance, and on the afternoon of Day One, you will visit the Tokyo International Exhibition Center and investigate real robot. You will be able to experience fun and excitement of advanced robot technologies. On the morning of Day Two, you will present your study and investigation results. On the afternoon of Day Two, as the final event, awards will be given by the RSJ to groups that have given outstanding presentations. We hope that many future robot researchers and engineers will be born today.
Answer: Senior high school students worldwide.

SOLUTION: Who is the Conference intended for?

PROBLEM: Article: Ethiopia has greatly reduced its death rates for children under the age of five years during the last two decades, new UN statistics show. The report says Ethiopia has cut the number of child deaths, by two thirds or so, to 68 per 1,000 births compared to that in 1990. The government owed the improved figures to its growing economy. Despite the reduction, the UN Children's Fund said Ethiopia needed to do much more to improve health facilities for pregnant women. Ethiopia is one of Africa's poorest states, although it has experienced rapid economic growth in recent years and is one of the continent's leading coffee producers. Its economy centers around agriculture, which in turn relies on rainfall. The BBC's Emmanuel Igunza in the capital, Addis Ababa, says Ethiopia was once representative of poor nutrition in Africa. But the latest UNICEF figures show Ethiopia is one of the few African countries on the path to realizing the development goal of reducing child death rates, he says. Ethiopia's Health Minister Kesetebirhan Admasu said increasing family incomes had helped improve people's health. "This has also resulted in better nutrition for children and women; this has translated into better medical conditions ---- all these have a direct or indirect influence on the survival of children," he told BBC Africa. He said the government has also been "aggressively expanding its primary health care network". "We have now 93% coverage( ) of one health centre for 25,000 people, which basically means one health facility within a 7km area," he said.
Answer: about 200

SOLUTION:
How many in 1000 births would die in Ethiopia in 1990?
