Explanation:

The Story of My Life is a heartbreaking story about the challenges faced by Keller and his teacher Sullivan to communicate with each other until Sullivan tried the method of spelling words in Keller's hands. With this method, Keller got a breakthrough into the world of communication.  

For the first time, Keller recognized the word 'water' through the method, and as she explained it in his book, "the word life, awakened my soul, gave it light, hope, joy, released it."

animal farm, written by george orwell, is a representation of russia after the revolution that led stalin to take over power.

in this excerpt, the central idea seems to be that the animals (a representation of society), when they believe to be working for a greater good and equality, are obedient and productive. they were convinced that, after expelling the owner (jones) from the farm, they would live in harmony and be fairly treated.

as we know, the pigs become the leaders and grow more selfish and dictatorial with time. in the end, they look and act in a way so similar to humans that it is impossible to tell the difference. the ideals of equality are shattered, and the farm turns out to be worse than it was before. the animals are manipulated with false propaganda and forced to work in order to enrich the pigs.
