Problem: Our sun and other stars release light energy. At least this is what we see. Our Sun and stars also emit more than just light. Scientists call the type of energy that our Sun and stars release electromagnetic energy. This form of energy travels through space. Electromagnetic energy includes the light we see. It also includes much more. Many of these things we know about, but dont always think about. Electromagnetic energy includes radio waves, microwaves, and X rays. We now have devices in our homes and offices that release these same forms of energy. We use electromagnetic energy to make our lives better. 

Question: "Besides the sun and the stars, what releases electromagnetic energy?"

Answer: "Devices in our homes and offices"

OPTIONS:
- no
- yes
Answer: yes
Question:
At 9:48, a representative from the White House shelter asked if there were any indications of another hijacked aircraft. The deputy director for operations mentioned the Delta flight and concluded that "that would be the fourth possible hijack." At 9:49, the commander of NORAD directed all air sovereignty aircraft to battle stations, fully armed. At 9:59, an Air Force lieutenant colonel working in the White House Military Office joined the conference and stated he had just talked to Deputy National Security Advisor Stephen Hadley. The White House requested (1) the implementation of continuity of government measures, (2) fighter escorts for Air Force One, and (3) a fighter combat air patrol over Washington, D.C. By 10:03, when United 93 crashed in Pennsylvania, there had been no mention of its hijacking and the FAA had not yet been added to the teleconference. The President and the Vice President The President was seated in a classroom when, at 9:05, Andrew Card whispered to him: "A second plane hit the second tower. America is under attack." The President told us his instinct was to project calm, not to have the country see an excited reaction at a moment of crisis. The press was standing behind the children; he saw their phones and pagers start to ring. The President felt he should project strength and calm until he could better understand what was happening. The President remained in the classroom for another five to seven minutes, while the children continued reading. He then returned to a holding room shortly before 9:15, where he was briefed by staff and saw television coverage. He next spoke to Vice President Cheney, Dr. Rice, New York Governor George Pataki, and FBI Director Robert Mueller. He decided to make a brief statement from the school before leaving for the airport. The Secret Service told us they were anxious to move the President to a safer location, but did not think it imperative for him to run out the door. Between 9:15 and 9:30, the staff was busy arranging a return to Washington, while the President consulted his senior advisers about his remarks. No one in the traveling party had any information during this time that other aircraft were hijacked or missing. Staff was in contact with the White House Situation Room, but as far as we could determine, no one with the President was in contact with the Pentagon.  After reading the above, is "No the cable was out" the correct answer to the question "Did The President see television coverage of the Delta 93 crash in Pennsylvania before leaving for the airport?"? OPTIONS:
- no
- yes

Answer:
no
Input: You know that friction also causes heat. Think about when you rub your hands together. It is friction that makes them warm. But why does this happen? Friction causes the molecules on rubbing surfaces to move faster. Faster moving particles have more heat energy. Heat from friction can be useful. Can you think of other places where you might find friction? Friction also lets you light a match. Heat from friction can also cause problems. It can cause a car to overheat. To reduce friction, oil is added to the engine. Oil coats the surfaces of moving parts. This coating of oil makes them slippery. When things are slippery there is less friction. Have you ever seen a sign that says, slippery when wet? This too has to do with friction. Water, like oil, can reduce friction. The wet surface may allow your shoes to slide more easily. 
"How does oil reduce friction between moving car parts?" is "Slippery"?

OPTIONS:
- no
- yes
Output: yes
Input: Little is known of the earliest Stone Age inhabitants of Europe's southwestern extremity. The ancient Greeks called them the Cynetes (or Cunetes). Whatever their origins, their culture evolved under the pressure and influence of foreign forces. Among the many invading armies that settled here and contributed to nascent Portuguese culture were Phoenicians, who settled in the area around 1,000 b.c., followed by the Celts, Iberians, Greeks, and Carthaginians. But it was the Romans, who arrived late in the third century b.c., who most greatly influenced all of Iberia. They built towns, industries, roads, and bridges, developed agriculture, and bequeathed the Latin language, of which Portuguese is a direct descendant. The Romans named the southwestern province of the peninsula Lusitania, oddly enough for one of the Celtiberian tribes they defeated, and by the third century a.d. had introduced Christianity. By the beginning of the fourth century the Algarve had a bishop in place, based in Faro. But Rome had already fallen into decay, and soon hordes of northern tribesmen took over the empire. The Algarve fell to the Visigoths in the mid-fifth century. Under Moorish Rule In a.d. 711, the Moors brought powerful armies from North Africa and launched a devastating attack on the Iberian peninsula, conquering much of what would become Spain and Portugal. They imposed Islam and left an indelible influence on the countryside and the population of the Algarve. The Moorish legacy can still be seen in the form of wells and waterwheels, squat white houses, the dark complexions of the people, and in the very name given the region — taken from Al-Gharb, which means "country of the west" (when the Moors conquered the territory, it was the most westerly in the known world). The Moors governed their Iberian kingdoms from across the border in Seville, but the Algarve had its own regional capital and huge, invulnerable fortress. The capital was Chelb (or Xelb), and it was bigger and better defended than Lisbon. Today the town, known as Silves,  is a provincial outpost whose only besiegers are busloads of tourists who climb the narrow streets up to the old Moorish ramparts. 

Does the response "Cynetes" correctly answer the question "What did the Greeks call the earliest Stone Age inhabitants of Europes's southwestern extremity?"?

- no

Input: Have you ever looked closely at a globe? That continents look like a giant jig-saw puzzle. North America looks like it could fit next to Europe. The edge of South America matches Africa. Scientists noticed these same features. It caused them to start asking questions. They wanted to know if these continents were was connected? If so, how can something so large move so far? What could possibly have enough force to move such a giant slab of rock? Is there other evidence that can provide clues to the past positions of continents? How can answering these questions help us? A scientist named Alfred Wegener had these same questions. Wegener look at rocks on both sides of the Atlantic Ocean. He noticed they were the same type and age. He thought that the rocks must have formed side by side. He proposed that the rocks then drifted apart. One part went with North America. The other part stayed with Europe. 
"Why does Wegener propose the continents look like a giant jigsaw puzzle?" is "They look like they could fit next to each other"?

OPTIONS:
- no
