A robot learns that questions are better than quick answers.
Pico was a little robot who helped in a school library. Children asked him, "Where is the book on elephants?" and Pico always knew.
One day a girl asked, "Pico, why is the sky blue?" Pico answered at once, but then he asked, "Why do YOU think it is blue?"
The girl thought hard. "Maybe the sun's light spreads out?" she said. "That is a wonderful idea!" said Pico. They looked in a book together and found she was nearly right.
From then on, Pico did not just give answers; he asked the children to think too. And that is how the library became the happiest place in the school.
