Article: A special laboratory at the University of Chicago is busy only at night. It is a dream laboratory where researchers are at work studying dreamers. Their findings have discovered that everyone dreams from three to seven times a night, although in ordinary life a person may remember none or only one of his dreams. While the subjects--usually students--sleep, special machines record their brain waves and eye movements as well as the body movements that signal the end of a dream. Surprisingly, all subjects sleep soundly. Observers report that a person usually fidgets before a dream. Once the dream has started, his body relaxes and his eyes become more active, as if the curtain had gone up on a show. As soon as the machine shows that the dream is over, a buzzer wakens the sleeper. He sits up, records his dream, and goes back to sleep--perhaps to dream some more. Researchers have found that if the dreamer is wakened immediately after his dream, he can usually recall the entire dream. If he is allowed to sleep even five more minutes, his memory of the dream will have disappeared. Question: Their finding has discovered that _ . Yes or no, is the answer "everyone dreams every night"?
No

Article: When I first heard about geocaching ,I was skeptical. But the more I thought about it, the more it seemed like an interesting idea.I at least wanted to try it once. Having familiarized myself with how the game works,I set out in search of my first cache. My trip took me through a series of lively hutong ,past a number of small temples, and right into the courtyard of a quiet youth hotel.I spent several minutes looking around, but couldn't find anything. Just before l was about to give up,I spotted a colorful object in the crack of a wall. Could it be the hidden cache? At that moment a group of backpackers amved. According to the game's rules, people who are not in the game must not be allowed to find out about secret caches. So I pretended to make a phone call while waiting for them to leave. When the coast was clear,I grabbed the object. It was the cache! I opened it and pulled out a crumpled sheet of paper with several names and celebratory messages written on it.I added my own and replaced the cache in its hiding place, ready for the next geocacher to find. It may seem like a simple game, but the idea that there are caches hidden all around us is exciting. Once you're hooked, it's easy to set yourself the goal of finding every single cache in a neighborhood or even an entire city. The real treasure, however, is not the cache itself, but the places it takes you to. Hunting for further caches has since introduced me to places which I didn't even know existed. Some are peaceful parks, while others are forgotten historical sites.A few caches have even been in places I passed regularly without giving them any thought. Now,Ifeel a much closer connection. Question: Where did the author find the cache? Yes or no, is the answer "In a hotel."?
(Answer)
No
