Article: Scientists have transformed men's minds into avirtual woman's body in an experiment that could throw light upon how humans distinguish themselves form others. In a study at Barcelona University, men wore a virtual reality headset that allowed them to see and hear the world as a female character. When they looked down, they could even see their new body and clothes. The "body-swapping" effect was so convincing that the men's sense of self was transferred into the virtual woman, causing them to react to events in the virtual world they wereimmersed . "This work opens up another avenue for virtual reality, which is not just to transform your sense of place, but also your sense of self," said Mel Slater, "If you can temporarily give people the illusion that their bodies are different, then the evidence suggests it also affects their behavior and the way they think. They can have new experiences: a person who is thin can know what it is like to be fat. A man can have an experience of what it's like to be a woman." During the experiment, a "female" approached and hit the face of the character another man was playing. "Their reaction was immediate," said Slate. "They would take in a quick breath and maybeflinch . The more people reported being in the girl's body, the stronger physical reaction they had." But in all cases, the feeling was temporary and lasted only as long as the study. The study shows that our minds have a very fluid picture of our bodies. The research is expected to shed light on the puzzle of how our brain tells the difference between a part of our own body and something else in the wider world. Thus the work might improve the conditions for those who have experienced strokes by placing them in a world that helps them to use their bodies to the full again. Question: How can a man's mind get into a woman's body? Yes or no, is the answer "by wearing a special device"?
No

Article: The longest day of the month is the day after my younger brother T.J gets his new issue of Just Joking , a magazine filled with all kinds of jokes. When the new issue arrives, T.J tells me every riddle in it . But a constant stream of riddles can get annoying . "Hey, Keith ! What did he hamburger name his daughter ?" "T.J !" I shout .

Usually he brings Just Joking to the table with him and tells us some riddles in between bites of food .This evening, he does not .I'm relieved . At last --- some peace and quiet. After dinner, I go to my friend Brad's house to work on a project for science class . We're painting the planets when Brad's little sister, Nita, comes into the room. "Brad, can I help you with the project ?" Nita asks. "Nita !" He shouts at her . "Leave us alone!" Nita walks out of the room looking sad. I feel bad for her. I can tell that she just wants to be around her big brother. The look on Nita's face reminds me of the look on T.J's face earlier in the evening .

Article: Can a fish hear fishermen moving along the stream? What are the facts about the ability of a fish to see? Can they tell the difference between colors? The sharp hearing of a fish has been proved by two scientists, who trained a fish to expect its food when it heard the sound of a whistle. And a slight sound two hundred feet away could drive fishes away. That should make fishermen start thinking. One scientist had made experiments to prove fish can recognize different colors such as red, brown, yellow and green. Fish also have an eye for different shapes. One scientist proved this by teaching fish to connect certain patterns with food. He used a small circle and a square. If the fish swam towards the circle, they received food as a reward. If they swam towards the square, they received nothing. The fish learned in time to go to the circle but not to the square. Does this mean that in time fish might learn to leave alone all food on hooks that they have seen often before? Here is something for all fishermen to think about! These facts help to make more believable some of the "believe it or not" stories that have been told about fish. It is clear that fish have sometimes shown their ability to gain knowledge as man does. A good example of what we might call "thinking" by a fish is given by an experience of Dr. Andrew Gage. Fishing over a bridge, he hooked a fish. It struggled and dragged the line two hundred feet away before he stopped it. Then it swam back to the bridge. The clever fish then swam round a pile and, with a sudden push, broke the line. If the story ended there, one could say that the fish had freed itself by chance. However, Gage went on fishing. Below him he could see the fish that had broken loose. After another twenty minutes the fish again seized the food on the hook. This time it did not swim out but swam round one of the piles and again broke the line. Many stories are told of the fish that get away and the clever "old hand" ones that can't be caught. The more often a fish is nearly caught,... Question: What's the best title of the passage? Yes or no, is the answer "How clever is a fish?"?

No
