question:
The idea that Earth is a magnet is far from new. It was first proposed in 1600 by a British physician named William Gilbert. Knowing it acts like a magnet is one thing. Knowing why it acts like a magnet is more difficult. In fact, finding out why is a fairly recent discovery. To find out why required new technology. It was the seismograph that made it possible to learn why the Earth acted like a magnet. Seismograph are used to study earthquakes. By studying earthquake waves they were able to learn about Earths interior. They discovered that Earth has an inner and outer core. The outer core consists of liquid metals, mainly iron and nickel. Scientists think that Earths magnetic field is generated here. It is caused by the motion of this liquid metal. The liquid metal moves as Earth spins on its axis. <sep>What technology made it possible to test the Earth's magnetic properties? How were scientist able to use this machine to study this phenomenon?<sep>Earth has an inner and outer core. The outer core consists of liquid metals, mainly iron and nickel.

answer:
No


question:
He continued to lie in place, still breathing heavily. I tried to keep myself calm. Then, with a sigh, he said, "I have need of a certain stone that I once possessed. It would allow me to leave this bed, despite my current illness. My problem is that it was not made in this realm, but by a human, and only a human may handle it. The herb vendor will tell you where you can find it. If you would fetch me this stone, I would tell you what I can." "Of course we will fetch you the stone," Nepthys assured him. "You have our thanks." Outside, the thing at the herb cart nodded when we mentioned the stone. He told Nepthys the name of a woman who lived on a certain street, and we set off. When we reached the street, I expected some sort of temple, or a row of antiquaries, or at least a sleazy, black-market relics merchant. Instead, it looked like we were in the red-light district: women who probably wanted more than our money eyed us from the alleys. Nepthys didn't need to warn me not to speak to them. He took us to the door of a building like a short pagoda that had a sign hanging over it showing a face with hands uplifted, like a saint under G d's light, and handcuffed. Inside, the entrance room was hung with bright silks and scattered with velvet cushions. Sails of obscene orange and a green that insulted springtime hung draped across reds that might have been sensual elsewhere but here were only offensive. A large woman, similarly decorated, quickly drifted up to us. "Good evening, gentlemen," she said. "May I invite you to have a cup of tea?" "No, thank you," said Nepthys, "we regret that we cannot take up your kind offer. Are you the proprietor of this shop?" "Yes," answered the woman. "I am Madame Entera, at your service. <sep>Who can tell me where to find the stone?<sep>The Herb Vendor
answer:
Yes


question:
The day was just breaking, as I left the tower; though it was still too dark in the house to be able to see without a light, and I took one of the study candles with me on my 'round.  By the time I had finished the ground floor, the daylight was creeping in, wanly, through the barred windows.  My search had shown me nothing fresh.  Everything appeared to be in order, and I was on the point of extinguishing my candle, when the thought suggested itself to me to have another glance 'round the cellars.  I had not, if I remember rightly, been into them since my hasty search on the evening of the attack.  For, perhaps, the half of a minute, I hesitated.  I would have been very willing to forego the task--as, indeed, I am inclined to think any man well might--for of all the great, awe-inspiring rooms in this house, the cellars are the hugest and weirdest.  Great, gloomy caverns of places, unlit by any ray of daylight.  Yet, I would not shirk the work.  I felt that to do so would smack of sheer cowardice.  Besides, as I reassured myself, the cellars were really the most unlikely places in which to come across anything dangerous; considering that they can be entered, only through a heavy oaken door, the key of which, I carry always on my person. <sep>Why wouldn't you search the cellar?<sep>It is scary
answer:

Yes
