Example Input: Though prehistoric remains from the Paleolithic, Neolithic, and Bronze Ages have been unearthed in the Manzanares Valley, prior to Madrid's sudden elevation to capital city in 1561 its history was rather undistinguished. Over a period of many centuries crucial in Spanish history, Madrid's significance was negligible. The Romans built their most advanced outpost on the Iberian peninsula, but left nothing of consequence in Madrid. Armies of North African nomads, intent on disseminating Islam, invaded the peninsula in a.d. Within 10 years, they had overrun most of Spain. If Madrid played any role in these pivotal events, no record of it remains. The first solid references to this obscure settlement on the Castilian plateau, guarded by the looming Guadarrama mountain range, appear in the 9th century. The Arabic name for "place of many springs," variously recorded as Magerit, Mayrit or Magrit, eventually evolved into Madrid. The hamlet entered historical chronicles for its military significance; it was located near the main line of resistance to the Christian reconquest. Over centuries of struggle, the defending Moorish army built a full-scale fort, or Alcazar, on the heights of Madrid commanding the Manzanares valley. After several unsuccessful skirmishes, the Christian forces of Alfonso VI captured Madrid in 1083. The Alcazar became a fort of the crown of Castile. During a counter-offensive in 1109, the town was overrun by the Moors, but the Christianized fortress held. The Moors were expelled from the town, but they remained in control of southern Spain for almost four centuries. Meanwhile, Madrid enjoyed brief prominence in 1308 when king Ferdinand IV and his Cortes, an early version of parliament, held a formal meeting in the fledgling town. From then on, the kings of Spain began to visit Madrid, where the air was invigorating and the hunting excellent. Ferdinand and Isabella, the Catholic monarchs that united all the provinces of Spain, first visited Madrid in 1477. <sep>Why did kings of Spain visit Madrid?<sep>Women

Example Input: Her career started more than 20 years ago in a garage behind a Catholic Worker soup kitchen on skid row in Los Angeles. She lived on a $3-a-week stipend that she spent on pantyhose and bus fare. Her law practice grew to an organization that brought in millions of dollars of damages through its cases against L.A. slumlords, allowing poor families to set up college funds and buy homes. In all those years, she never lost a case. When she stepped down, she had time to notice what was happening to the field of poverty law. "I realized with a shock that the work had really disintegrated and we had lost a whole generation of public-interest lawyers," she said. "It had gone from being an economic sacrifice as it was in my day to an economic impossibility. ... The whole system has essentially collapsed." Mintie also started to ask questions about the medical field. Almost every person who walks into a free medical clinic, she said, faces some legal problem such as an eviction or the loss of Social Security benefits. And many of her clients had medical problems from living in slum housing such as cockroaches lodged in ear canals and rat bite fever, a nonfatal malady that particularly affects children. Mintie noticed that health-care professionals were graduating with staggering debts and also couldn't afford to work with the poor. Her work was noticed by Oprah Winfrey, who invited her on the TV show March 26, 2001. Mintie received a $100,000 "Use Your Life Award" from Oprah's Angel Network, a nonprofit organization that awards money to those who help others. Mintie said that all of the money has gone to her recipients -- none was spent on overhead. She will be out of funds by spring. She is trying to get religious organizations to sponsor recipients. It is a secular organization, but one that grew out of Mintie's religious convictions. <sep>How many years did Mintie go without losing a case?<sep>20 years
Example Output: Yes

Example Input: Paris, France (CNN) -- Hundreds of French workers, angry about proposed layoffs at a Caterpillar factory, were holding executives of the company hostage Tuesday, a spokesman for the workers said. Caterpillar's French staff say they are angry about a lack of negotiations over layoffs. It is at least the third time this month that French workers threatened with cutbacks have blockaded managers in their offices to demand negotiations. Executives were released unharmed in both previous situations. The latest incident started Tuesday morning at the office of the construction equipment company in the southeastern city of Grenoble. The workers were angry that Caterpillar had proposed cutting more than 700 jobs and would not negotiate, said Nicolas Benoit, a spokesman for the workers' union. They did not want to harm the Caterpillar executives, Benoit told CNN. One hostage was released Tuesday evening leaving workers with four captives inside the Caterpillar building. The released man was a human resources director identified only as Mr. Petit, because he has heart problems, union representative Bernard Patrick told CNN. Petit had a heart attack a few weeks ago, Patrick said. The four others still being held are Nicolas Polutnik, the head of operations; two other executives; and Petit's personal assistant, he said. About 500 employees were also outside the building protesting. <sep>How many people besides Mr. Petit were held hostage?<sep>7
