Sent 2: First of the national rulers to take the title of sei-i tai-shogun ("barbarian-subduing great general"), Minamoto expanded and consolidated his power by confiscating lands from some of the defeated Taira and redistributing them to his samurai vassals.
Sent 3: Minamoto died in 1199, and the feudal structure passed intact to the tutelage of his widow's family, the Hojo, who were content to play regent to a figurehead shogun, in much the same way as the Fujiwara had done with the emperor.
Sent 4: The fiction of Japanese imperial power had become infinitely extendable.
Sent 5: The emperor at Kyotostill seconded by a Fujiwara regent at courtlegitimized a Minamoto who was himself a military dictator controlled by a Hojo regent.
Sent 6: In a country where form and substance were inextricably interrelated, two things counted in politics: symbolic authority and real power.
Sent 7: Neither could exist without the other.

Sent 10: And the treasury was empty after earthquake, famine, and plague had crippled the economy.
Sent 11: Buddhist monasteries were using their private armies to support imperial ambitions to bring power back to Kyoto.
Sent 12: Worst of all, the Kamakura warriors, resenting the way the Kyoto court referred to them as "Eastern barbarians," sought refinement in a ruinous taste for luxury: extravagant feasts, rich costumes, and opulent homes.
Sent 13: Kamakura was falling apart.
Question: How did Minamoto expand his power?.

Sent 2: Millions of men and women readied themselves for work.
Sent 3: Some made their way to the Twin Towers, the signature structures of the World Trade Center complex in New York City.
Sent 4: Others went to Arlington, Virginia, to the Pentagon.
Sent 5: Across the Potomac River, the United States Congress was back in session.
Sent 6: At the other end of Pennsylvania Avenue, people began to line up for a White House tour.
Sent 7: In Sarasota, Florida, President George W. Bush went for an early morning run.
Sent 8: For those heading to an airport, weather conditions could not have been better for a safe and pleasant journey.
Sent 9: Among the travelers were Mohamed Atta and Abdul Aziz al Omari, who arrived at the airport in Portland, Maine.
Sent 10: Boston: American 11 and United 175.
Sent 11: Atta and Omari boarded a 6:00 A.M. flight from Portland to Boston's Logan International Airport.
Sent 12: 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.
Sent 13: 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.
Sent 14: This did not hinder Atta's plans.
Sent 15: Atta and Omari arrived in Boston at 6:45.
Sent 16: Seven minutes later, Atta apparently took a call from Marwan al Shehhi, a longtime colleague who was at another terminal at Logan Airport.
Sent 17: They spoke for three minutes.
Sent 18: It would be their final conversation.

Input: Consider Input: Paragraph- Sent 1: Flowing water causes sediment to move.
Sent 2: Flowing water can erode both rocks and soil.
Sent 3: You have already learned that materials can dissolve in water.
Sent 4: With enough time, even rocks can be dissolved by water.
Sent 5: This process happens really slowly.
Sent 6: It may take over a million years to dissolve a rock.
Sent 7: It doesnt matter how big the rock is.
Sent 8: With enough time, flowing water can dissolve it.
Sent 9: Moving water also has the ability to move small pieces of rock and soil.
Sent 10: How can water move a rock?
Sent 11: Doesnt it need energy?
Sent 12: Of course, water gets its energy because it is moving.
Sent 13: Moving water has kinetic energy.
Sent 14: Things that have more energy can do more work.
Sent 15: When water stops moving it will have no energy.
Sent 16: It will no longer be able to move the rock and soil.
Sent 17: When this happens the rock and soil will settle to the bottom of the calm water.
Sent 18: Scientists call this process deposition.
Question: Why can water that is moving more do more work than water that is moving less?.
Output: Water that is moving more has more kinetic energy; things that have more energy can do more work.
