Input: Magnetism is the ability of a material to be attracted by a magnet. It also include the ability for some material to act like a magnet. No doubt youve handled refrigerator magnets. You can see some in Figure 1.28. You probably know they stick to a metal refrigerator. This is what holds your homework up. Maybe your little sisters drawings are hung on the fridge in this manner. Do magnets stick to all materials? Of course not. You have probably checked and they do not stick to other surfaces. They do not stick to wooden doors or glass windows. Wood and glass are not attracted to a magnet. Obviously, only certain materials are attracted to magnets.
"Do magnets stick to all materials?" is "Only certain materials are attracted to magnets"?

OPTIONS:
- no
- yes
Output: yes

Input: It is not enough to describe some objects by their location. We may also need to know its direction. For example, a wind blows a storm over your school. Where is that storm coming from? Where is it going? How can we describe a direction? The most common way is by using a compass. A compass is a device with a floating needle (Figure 2.1). The needle is a small magnet. The needle aligns itself with the Earth's magnetic field. The compass needle always points to magnetic north. If you have a compass and you find north. You can then know any other direction. See the directions, such as east, south, west, etc., on a compass rose. The Earth has two poles. It has a magnetic north pole. It also has a geographic north pole. These two poles are close to each other but not the exact same place.

Does the response "The Earth has a magnetic east pole and a geographic west pole." correctly answer the question "What poles does the Earth have?"?

In her storage room-turned-office, Jennifer Baum works under an expanding leak that is causing the ceiling to turn brown and crumble. Mold grows in the buckets positioned to catch the water. She shrugs it off. Outside her office she has taped up a clear plastic suit, and a sign that reads, "All employees must don protective gear before coming in." Such is life in limbo. Nearly a year after Sept. 11, the Legal Aid Society-the lawyers for New York's poor and homeless-remains, well, homeless. The nonprofit has been barred from returning to its 90 Church St. headquarters, across from the World Trade Center site, because of environmental concerns. Legal Aid has uncomfortable company. More than 11,500 New Yorkers continue to work out of temporary space, according to analysis by Manhattan-based real estate brokerage TenantWise.com Inc. and Crain's New York Business. That's 8% of the 137,000 workers who lost their offices or access to them when the Twin Towers collapsed. Legal Aid's 450 displaced attorneys and staffers have spent the past 12 months spread among previously unused spaces-some unused for good reason-in the nonprofit's other offices. It could be another year and a half before they return to their old desks. They have contended with difficult working conditions as demand for Legal Aid's services is on the rise because of Sept. 11 and the deteriorating economy. The civil division is spread among a few boroughs. Their papers and documents, some 20,000 boxes worth, are stuck in a storage facility in Linden, N.J. "I am counting the days till we can have all the parts back in one place," says Steven Banks, Legal Aid's associate attorney in chief. In the memories of the exiled workers, the old office has achieved mythical proportions. They say the wood paneling and rugs had the ability to cool emotions and lift spirits. The Legal Aid office on Montague Street in Brooklyn Heights, where 65 displaced workers have cobbled together space amid the faded and scratched walls, looks more like a bargain basement.

Problem: 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.

Question: "Who can tell me where to find the stone?"
