The answer is: explanation: the tiger shows his wrath silently since he can't do anything from behind his cage's bars. He is helpless since his strength has been imprisoned inside the cage owing to man's whims. The poet calls the tiger's anger "quiet" because it cannot be expressed through words; rather, it takes place internally. This poem was written by Lord Byron. His family had money, so they weren't poor, but they were still working class. His father was a doctor, but he died when Byron was only nine years old. After this, his mother had to work very hard to support them so she could not spend much time with her son. When he was fifteen, he went to school for a few months but then had to leave because there was no money for tuition. Byron did not have any other choice than to become a lawyer like his father because lawyers were well paid at the time. However, he felt that this life was not for him so he left England and went to live in Italy. There he enjoyed all sorts of activities including writing poems. But most of all, he loved traveling around Europe visiting cities and museums.
