Read the following passage ans answer the questions-
Once (once only) I went absent-mindedly into his shop in a pair of boots bought in an emergency at some large firm. He took my order without showing me any leather and I could feel his eyes penetrating the inferior covering of my foot. At last he said, “Dose are nod my boods.” The tone was not one of anger, nor of sorrow, not even of contempt, but there was in it something quiet that froze the blood. He put his hand down and pressed a finger on the place where the left boot was not quite comfortable. “Id ’urds’ you dere,” he said, “Dose big virms ’ave no self-respect.” And then, as if something had given way within him, he spoke long and bitterly. It was the only time I ever heard him discuss the conditions and hardships of his trade.
“Dey get id all,” he said, “dey get id by advertisement, nod by work. Dey take id away from us, who lofe our boods. Id gomes to dis— bresently I haf no work. Every year id gets less. You will see.” And looking at his lined face I saw things I had never noticed before, bitter things and bitter struggle and what a lot of grey hairs there seemed suddenly in his red beard! As best I could, I explained the circumstances of those ill-omened boots. But his face and voice made so deep an impression that during the next few minutes I ordered many pairs. They lasted longer than ever. And I was not able to go to him for nearly two years.
