Read the passage carefully and answer the questions that follow:

Dr Solomon Margolin took a last look in the mirror and left the house. He felt refreshed by the half-hour nap he had had after dinner. Despite his age, he still wanted to impress people with his appearance-even the Senciminers. He had his illusions. In Germany he had taken pride in the fact that he looked like a Junker, and in New York he was often aware that he could pass for an Anglo-Saxon. He was tall, slim, blond, blue-eyed. His hair was thinning, had turned somewhat grey, but he managed to disguise these signs of age. He stooped a little, but in company was quick to straighten up. Years ago, in Germany he had worn monocle and though in New York that would have been too pretentious, his glance still retained a European severity. He had his principles. He had never broken the Hippocratic Oath. With his patients he was honourable to an extreme, avoiding every kind of cant; and he had refused a number of dubious associations that smacked of careerism. Gretl claimed his sense of honour amounted to a mania. Dr Margolin’s car was in the garage - not a cadillac like that of most his colleagues - but he decides to go by taxi. He was unfamiliar with Brooklyn and the heavy snow made driving hazardous. He waved his hand and at once a taxi pulled over to the curb. He was afraid the driver might refuse to go as far as Brownsville, but he flicked the meter on without a word.
