Example Input: 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
Example Output: Yes

Example Input: (OPRAH.com) -- Chris Rock is an Emmy-winning comedian, devoted husband and loving father --but it's time to get to know a new side of this funnyman. Meet Chris Rock, hair expert. It's a detour he took after an innocent carpool ride left Rock with an idea he just couldn't shake. "I was with my daughter one day, and we're in the car and she's with one of her friends in the back seat, a little white friend," he says. "She was just kind of raving about her friend's hair a little too much for my comfort [saying]: 'You've got great hair. Oh, your hair's so good.'" Not wanting to make her comments a big deal, Rock says he tried to play his them off. "[I said]: "Oh, baby, your hair's beautiful. Come on,'" he says. "If I would have really reacted, then she would have a complex about her hair." Still, Rock couldn't let it go. "It sparked something in me," he says. Oprah.com: Oprah's hair throughout the years! What Rock discovered is a $9 billion industry that affects the daily activities, wallets, self-esteem -- and even the sex lives -- of black women. Because women spend so much time and money on their hair, Rock says men are forced to adopt a hands-off policy. "You cannot touch a black woman's hair. You are conditioned not to even go there," he says. "When I was a dating guy, I dated women from different races. Anytime I was with an Asian or a Puerto Rican girl or a white girl, my hands would constantly be in their hair. <sep>Which women do not allow men to touch their hair, according to Chris Rock?<sep>White women

Example Input: Once upon a time I had a dog named Toodles. He was black and white and had long floppy ears. He also had very short legs, but really big paws. Every Saturday we would go to the park and play Toodles' favorite game. Toodles loved playing fetch. One Saturday, Toodles ran over to the pond because he saw ducks swimming there. He ran all around the pond, barking at the ducks. The ducks ignored him, and kept swimming. Toodles wasn't having it! He jumped into the pond and started swimming toward the ducks, chasing around his new playmates. One of the ducks, braver than the others, poked Toodles with his beak - and then bit him right on one of his floppy ears! Toodles barked and ran out of the pond because the duck hurt his ear. Soaking wet, he ran toward where I was eating a sandwich on the grass and curled right up in my lap so I could make him feel better. After that, whenever he would see a duck, Toodles would run the other way. <sep>Where was the pond<sep>At home
