Example Input: The judge leaned back in his chair and beckoned to Mr. Andrews. It was finished. Spear was free, and from different parts of the courtroom people were moving toward the door. Their numbers showed that the friends of the young man had been many. Mr. Thorndike felt a certain twinge of disappointment. Even though the result relieved and pleased him, he wished, in bringing it about, he had had some part. He begrudged to Isaacs & Sons the credit of having given Spear his liberty. His morning had been wasted. He had neglected his own interests, and in no way assisted those of Spear. He was moving out of the railed enclosure when Andrews called him by name. "His honor," he said impressively, "wishes to speak to you." The judge leaned over his desk and shook Mr. Thorndike by the hand. Then he made a speech. The speech was about public-spirited citizens who, to the neglect of their own interests, came to assist the ends of justice, and fellow-creatures in misfortune. He purposely spoke in a loud voice, and every one stopped to listen. "The law, Mr. Thorndike, is not vindictive," he said. "It wishes only to be just. Nor can it be swayed by wealth or political or social influences. But when there is good in a man, I, personally, want to know it, and when gentlemen like yourself, of your standing in this city, come here to speak a good word for a man, we would stultify the purpose of justice if we did not listen. I thank you for coming, and I wish more of our citizens were as unselfish and public-spirited." It was all quite absurd and most embarrassing, but inwardly Mr. Thorndike glowed with pleasure. It was a long time since any one had had the audacity to tell him he had done well. <sep>Who did Mr. Thorndike want to help?<sep>Himself
Example Output: No

Example Input: Tuesday, September 11, 2001, dawned temperate and nearly cloudless in the eastern United States. Millions of men and women readied themselves for work. Some made their way to the Twin Towers, the signature structures of the World Trade Center complex in New York City. Others went to Arlington, Virginia, to the Pentagon. Across the Potomac River, the United States Congress was back in session. At the other end of Pennsylvania Avenue, people began to line up for a White House tour. In Sarasota, Florida, President George W. Bush went for an early morning run. For those heading to an airport, weather conditions could not have been better for a safe and pleasant journey. Among the travelers were Mohamed Atta and Abdul Aziz al Omari, who arrived at the airport in Portland, Maine. Boston: American 11 and United 175. Atta and Omari boarded a 6:00 A.M. flight from Portland to Boston's Logan International Airport. When he checked in for his flight to Boston, Atta was selected by a computerized prescreening system known as CAPPS (Computer Assisted Passenger Prescreening System), created to identify passengers who should be subject to special security measures. Under security rules in place at the time, the only consequence of Atta's selection by CAPPS was that his checked bags were held off the plane until it was confirmed that he had boarded the aircraft. This did not hinder Atta's plans. Atta and Omari arrived in Boston at 6:45. Seven minutes later, Atta apparently took a call from Marwan al Shehhi, a longtime colleague who was at another terminal at Logan Airport. They spoke for three minutes. It would be their final conversation. <sep>How long was the phone call Between Atta and Marwan al Shehhi<sep>1 minute
Example Output: No

Example Input: When a stream or river slows down, it starts dropping its sediments. Larger sediments are dropped in steep areas. Some smaller sediments can still be carried by a slow moving stream or river. Smaller sediments are dropped as the slope becomes less steep. Alluvial Fans In arid regions, a mountain stream may flow onto flatter land. The stream comes to a stop rapidly. The deposits form an alluvial fan. Deposition also occurs when a stream or river empties into a large body of still water. In this case, a delta forms. A delta is shaped like a triangle. It spreads out into the body of water. <sep>Are larger sediments dropped in steeper or less steep areas than smaller sediments in the same stream?<sep>Less steep
Example Output:
No
