Reporters and city officials gathered at a Chicago railroad station one afternoon in 1953. The person they were meeting was the 1952 Nobel Peace Prize winner. A few minutes after the train came to a stop, a giant of a man - six feet four inches - with bushy hair and a large moustache stepped out from the train. Cameras flashed. City officials approached him with hands outstretched. Various people began telling him how honoured they were to meet him.

The man politely thanked them and then, looking over their heads, asked if he could be excused for a moment. He quickly walked through the crowd until he reached the side of an elderly black woman who was struggling with two large suitcases. He picked up the bags with a smile, escorted the woman to a bus. After helping her aboard, he wished her a safe journey. As he returned to the greeting party he apologized, "Sorry to have kept you waiting." Not many whites would have done what he did.

The man was Dr. Albert Schweitzer, the famous missionary doctor who had spent his life helping the poor in Africa. In response to Dr. Schweitzer's action, one member of the reception committee said with great admiration to the reporter standing next to him, "That's the first time I ever saw a sermon walking."

A) speak louder than his words B) be admired

Read the passage carefully and select the best answer to each question out of the given four alternatives.

 

India’s title triumph in the Under-19 cricket World Cup at the Bay Oval in New Zealand seemed inevitable. Prithvi Shaw’s boys, astutely coached by Rahul Dravid, maintained an unbeaten record through their three-week sojourn. The rousing campaign commenced with a 100-run win against Australia on January 14; in subsequent games, Papua New Guinea, Zimbabwe, Bangladesh and Pakistan were all emphatically defeated. There were no big-game nerves and even in the much- hyped semifinal against Pakistan, India pocketed a facile 203-run victory. In the summit clash against Australia, Shaw’s boys followed their template of dominance.

Australia was bowled out for 216 and India cruised home in 38.5 overs with eight wickets to spare, and enjoyed the added lustre of opener Manjot Kalra’s unbeaten 101. Through the tournament India found diverse heroes. Fittingly, its batting troika of Shaw, Kalra and Shubman Gill, along with seamer Kamlesh Nagarkoti and spinner Anukul Roy, found a berth in the International Cricket Council’s Under-19 World Cup team, essentially a tribute to the best players on view in the championship. Cricketing excellence allied with the resultant celebrity status, especially during the teenage years, can be a double-edged sword and it helped that in the dressing room there was the calming presence of Dravid. As the ecstatic players leapt and photo-bombed after clinching the trophy, Dravid cut through the hype and said that this win should not be the team’s defining memory as each individual cricketer has much more to achieve in his career. Dravid has a point. India has won the Under-19 World Cup on four occasions, including the previous golden runs in 2000, 2008 and 2012. From among these champion sides, only a few graduated to the big stage. Yuvraj Singh and Virat Kohli came through the under-19 ranks and managed to carve a niche for themselves, but Unmukt Chand, who led the team to the Cup in 2012, and then featured in a soft drink advertisement besides writing a book, has been unable to make it to the Indian senior team.

 

According to the passage, who is the captain of the U-19 Cricket World Cup team?

A) Prithvi Shaw B) Rahul Dravid
C) Manjot Kalra D) Shubman Gill
 
Answer & Explanation Answer: A) Prithvi Shaw
