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.
"Why did kings of Spain visit Madrid?" is "Because of a formal meeting"?

Input: Washington (CNN) -- The Pacific island nation of Palau has agreed to take in 17 Chinese Muslims held at the U.S. prison camp at Guantanamo Bay, Cuba, the country's ambassador to the United States said Wednesday. The map shows the Pacific island nation of Palau in relation to China. Details of the transfer are still being worked out, Ambassador Hersey Kyota told CNN. But Kyota said his country, a former U.S. Pacific trust territory, has agreed to take in the ethnic Uighur detainees "for humanitarian reasons" and because of the "special relationship" between Palau and the United States. U.S. State Department spokesman Ian Kelly would not comment on the announcement, telling reporters, "We're still involved in ongoing discussions." The agreement includes some U.S. aid for Palau, Kyota said, but he said those details remained to be worked out as well. The country, with a population of about 20,000, is about 1,000 miles southeast of Manila, Philippines, and about 4,600 miles west of Hawaii. Palau has received nearly $900 million in U.S. aid since independence in 1994, according to congressional auditors, and depends on Washington for defense. The "Compact of Free Association" between Palau and the United States is up for review, but Kelly said any additional aid offer "is not linked to any other discussions we may be having with the government of Palau." The Uighurs were accused of receiving weapons and military training in Afghanistan.

Does the response "Kyota" correctly answer the question "Who is ambassador to the United States from Palau?"?

If you have a mass of 50 kg on Earth, what is your weight in newtons? An object with more mass is pulled by gravity with greater force. Mass and weight are closely related. However, the weight of an object can change if the force of gravity changes. On Earth, the force of gravity is the same everywhere. So how does the force of gravity change? It doesnt if you stay on Earth. What if we travel to another planet or moon in our solar system? Look at the photo of astronaut Edwin E. Aldrin Jr. taken by fellow astronaut Neil Armstrong in the Figure. They were the first humans to walk on the moon. An astronaut weighs less on the moon than he would on Earth. This is because the moons gravity is weaker than Earths. The astronauts mass, on the other hand, did not change. He still contained the same amount of matter on the moon as he did on Earth. If the astronaut weighed 175 pounds on Earth, he would have weighed only 29 pounds on the moon. If his mass on Earth was 80 kg, what would his mass have been on the moon? [Figure 3]

Question: "Why is it that a man on the moon who weighs 175lbs would only weight 29 pounds on the moon?"

OPTIONS:
- no
- yes

Answer: "Because the gravity on the moon is weaker"

Response: yes

The Principals Committee had its first meeting on al Qaeda on September 4. On the day of the meeting, Clarke sent Rice an impassioned personal note. He criticized U.S. counterterrorism efforts past and present. The "real question" before the principals, he wrote, was "are we serious about dealing with the al Qida threat? Is al Qida a big deal? Decision makers should imagine themselves on a future day when the CSG has not succeeded in stopping al Qida attacks and hundreds of Americans lay dead in several countries, including the US," Clarke wrote. "What would those decision makers wish that they had done earlier? That future day could happen at any time." Clarke then turned to the Cole." The fact that the USS Cole was attacked during the last Administration does not absolve us of responding for the attack," he wrote. "Many in al Qida and the Taliban may have drawn the wrong lesson from the Cole: that they can kill Americans without there being a US response, without there being a price."

Question: "Who states that "The Taliban may have drawn the wrong lesson from the Cole"?"

Response: "The Clinton Administration"

Problem: On a busy Friday morning in Manhattan, nine pedestrians suffered bullet or fragment wounds after police unleashed a hail of gunfire at a man wielding a .45 caliber pistol who had just killed a former co-worker. The officers unloaded 16 rounds in the shadow of the Empire State Building at a disgruntled former apparel designer, killing him after he engaged in a gunbattle with police, authorities said. Three passersby sustained direct gunshot wounds, while the remaining six were hit by fragments, according to New York Police Commissioner Ray Kelly. All injuries were caused by police, he said Saturday. One officer shot nine rounds and another shot seven. Police identified the gunman as Jeffrey Johnson, 58, who was apparently laid off from his job as a designer of women's accessories at Hazan Import Co. last year. Johnson, who served in the U.S. Coast Guard in the mid-1970s, had two rounds left in his pistol. It holds eight, Kelly said. Police identified the slain co-worker as Steven Ercolino, 41, who had apparently filed a prior complaint against his assailant, claiming that he thought Johnson would eventually try to kill him. Both men had filed harassment complaints against each other in April 2011, Kelly added. Ercolino was listed as a vice president of sales at Hazan Import Corp., according to his LinkedIn profile. "It's not something that should happen to a loving person like that," said his brother, Paul. "He's going to be so missed by everybody. He was a light of so many lives."

Question: "Who was interviewed about Ercolino's death?"

Answer: "His brother, Paul"
