Solution

The correct option is B two
In a full braille cell, we have six raised dots that are arranged in two columns. And each of these columns has three dots. The positions of the dot are determined by numbering them from one to six. Now, a single dot or any combination of the dots can be raised at any of the 6 positions to depict a specific letter or word.

Q. How are dots arranged in cells of Braille system?

A communication system for the blind that includes raised dots that are arranged to represent letters of the alphabet is called

Read the passage given below and choose the option that best fits the question that follows:

Although Louis Braille died when he was only forty-three years old, he succeeded in devising a system of reading and writing for the blind which is now taught all over the world. Braille lost his sight in an accident as a child. Nevertheless, he was able to complete his education at a school for the blind in Paris and became a teacher. In his day, the few books that were available for blind people were printed in big, raised type; the letters used were those of the ordinary alphabet. The reading of such books required an immense effort. Not only that, the writing was almost impossible, for a blind person was still restricted to an alphabet which was extraordinarily difficult to reproduce on paper. Braille's idea was to use raised dots, instead of raised letters. He evolved a system, which made use of only six dots in all. By various combinations of these dots, it not only proved possible to represent each letter of the alphabet but punctuation marks, numbers and musical notation as well. Reading and writing for the blind have thus become enormously simplified. The sensitive fingers of a blind person can travel rapidly over the dots; and there is a small machine, something like a typewriter, which enables the blind to write quickly and clearly.
