Read the following passage and choose the correct answer.Louis Braille was born in the nineteenth century. When he was three years old, a tragic accident at his father’s workshop left him blind permanently. As a young boy, Louis was hardworking and intelligent. His teachers suggested that he should be enrolled in the National Institute for Blind Youths. At that time, this was the only school for the blind in France.At the Institute, Louis was eager to learn to read and write. To his great disappointment, the few books he found at the institute used raised letter. This method of reading was difficult for the blind, who had to slowly feel each letter. By the time they reached the end a sentence, they had forgotten what the beginning was about!Louis wanted to develop an easier reading system for the blind. His idea of such a system came from Charles Barbier, a French army officer. Barbie had invented a system called “Night Writing”, which was made of dots and dashes. Soldiers used this system to communicate with one another during the night. Louis adapted this system for his own use, he got rid of the dashes and produced a simple system based on dots. For example, “A” is presented by a single dot, many student found this system much easier to use. This came to be known as the “Braille” system. Today, millions of blind people are able to read, thanks to the work of a dedicated, young blind man.
