Input: Rolfe put down the little dog he had been holding, and went out into the hall. The dog accompanied him, frisking about him in friendly fashion. Rolfe first examined the bedroom that he had seen Inspector Chippenfield enter. It was a small room, containing a double bed. It was prettily furnished in white, with white curtains, and toilet-table articles in ivory to match. A glance round the room convinced Rolfe that it was impossible for a man to secrete himself in it. The door of the wardrobe had been flung open by the inspector, and the dresses and other articles of feminine apparel it contained flung out on the floor. There was no other hiding-place possible, except beneath the bed, and the ruthless hand of the inspector had torn off the white muslin bed hangings, revealing emptiness underneath. Rolfe went out into the hall again, and entered the room next the bedroom. This apartment was apparently used as a dining-room, for it contained a large table, a few chairs, a small sideboard, a spirit-stand, a case of books and ornaments, and two small oak presses. Plainly, there was no place in it where a man could hide himself. The next room was the bathroom, which was also empty. Opposite the bathroom was a small bedroom, very barely furnished, offering no possibility of concealment. Then the passage opened into a large roomy kitchen, the full width of the rooms on both sides of the hall, and the kitchen completed the flat.

Does the response "Bedroom" correctly answer the question "What type of room did Rolfe examine?"?

- no

Enter the Shoguns: Japan's austere, ruthless, but statesmanlike new ruler, Yoritomo Minamoto, set up his government in Kamakura (just south of modern Tokyo), well away from the "softening" influence of court life that had been the undoing of his predecessor, Kiyomori. 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. 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. The fiction of Japanese imperial power had become infinitely extendable. The emperor at Kyotostill seconded by a Fujiwara regent at courtlegitimized a Minamoto who was himself a military dictator controlled by a Hojo regent. In a country where form and substance were inextricably interrelated, two things counted in politics: symbolic authority and real power. Neither could exist without the other. A thwarted Mongol invasion in 1274 weakened the Kamakura regime. The fighting brought none of the usual spoils of war that provincial warlords and samurai had come to expect as payment. And the treasury was empty after earthquake, famine, and plague had crippled the economy. Buddhist monasteries were using their private armies to support imperial ambitions to bring power back to Kyoto. 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. Kamakura was falling apart.

Question: "How did the economy collapse?"

OPTIONS:
- no
- yes

Answer: "Plague"

Response: yes

Magnets are able to place a force on certain materials. This force is called a magnetic force. The force a magnet exerts is a little different from the forces you may normally think about. You exert a force on a book when you lift it. You also exert a force on the pedals of your bicycle. In both those cases, those forces cause a change. The change you see in both these cases is called motion. Magnets, too, can produce change. They can produce motion just like you do. Unlike you, magnets do not have to touch something to exert a force. A magnetic force is exerted over a distance. Thats right, a magnet can push or pull certain items without ever touching them. Thats how the maglev train works. Do you know another type of force that does not require objects to touch? These forces are known as non-contact forces. Another type of non-contact force you may be familiar with is gravity. Gravity too can cause changes in motion. Gravity holds our moon in orbit without touching it.

Problem: Surely, you have noticed the tall poles along the roadside. Do you know what is on top of those poles? Thats right, wires that carry electric current. These wires carry electric current to your home. But what is electric current? Electric current is actually the flow of electrons. You may recall, an electron is the outer-most particle in an atom. They have a negative charge. Electricity is the continuous flow of these particles. Electrons are able to move through wires. Their speed can even be measured. The SI unit for electric current (or speed) is the ampere (A). Ampere is often shortened to amp. Electric current may flow in just one direction, or it may keep reversing direction. Direct current (DC) flows in only one direction. Direct current is what is used in devices like flashlights. Alternating current (AC) flows in two directions. This is the type of current that flows into your home through wires.

The side of Malaquez's parcel gave way to reveal a greenmunk caught in a sheen of solid air. Bits of leaf mold flew from under his feet as he ran to greet a friend or a bringer of food. Tasha oohed in awe. I said, "Frodo's been visiting you, eh?" Malaquez said, "Your pet?" "Hardly. He lives around here somewhere. I suppose he was attracted to the commotion up the hill." "Ah," Malaquez said. "Why 'Frodo'?" Tasha said, "A little fellow with big, furry feet. What else could he be called?" She handed the sculpture to me. I almost dropped it; I expected it to weigh no more than a holo. "Heavy," I said, as if he might not have known. He laughed. "My last piece was of four old Undersiders crouched around a trash fire. Be glad someone didn't toss that to you." He spoke of his art with the enthusiasm of a seven-year-old. "Um, I should wait to importune you, but..."

Question: "Where does Frodo live?"

Response: "In Tasha's house"
OPTIONS:
- no
