Q: Article: A father wanted to buy a horse for his son. After looking at many horses, the man's decision was almost made. It had come down to a choice between two horses. They were quite similar and the prices were the same. He decided to take another look so he could make a final decision. The first farmer was eagerly trying to sell his horse and talked much about how cute his horse was, but the father didn't reach a decision. The second farmer was different. He didn't say anything about the horse, but he simply said that he was sure the man's son would love his horse. He offered to bring the man a saddle , a bridle , the horse and enough food for it for 30 days. In return , the father should give him a check, and he would hold it for 30 days. If the man's son decided to keep the horse, he could let him know at the end of the 30 days, and he would cash the check. Otherwise, he would give back the man's check, pick up the horse and even clean up where the horse had been to. Which farmer do you think sold his horse? Can you see that if you promise buyers reliable business dealings with you, you are more likely to be successful? The farmer gave more far beyond what the father thought or even imagined.

Q: Article: In February 2006, Lydia Angyiou and her two sons were walking through their village in northern Canada. The sound of children shouting made her turn around. To her horror, Lydia saw a 700-pound polar bear behind her eyeing her seven-year-old son. Getting between the bear and her child, Lydia yelled at the children to run away. She then began hitting and kicking the animal as hard as she could. A neighbor who heard all the noise came and shot the bear. But everyone agreed it was Lydia who had saved her children's lives. A local policeman described it this way: "... I guess when your back is up against the wall, ... we come up with super-human strength." Where does this "super-human strength", courage and quick thinking come from? Experts say it comes from stress! In stressful situations, the body releases chemicals that prepare it to take action. These chemicals give people the speed and strength they need to fight danger or run away from it. When we think of stress, we usually think of its negative effects. Studies, though, show that moderate levels of stress are actually helpful. In fact, the way we perform is usually affected by the amount of stress we feel. Stress causes the brain to release adrenaline which in turn increases our energy and excitement. The chemical gives us clearer minds and helps us to do more. This is why some people say they work better under a deadline. Adrenaline that is not released for long periods of time can cause us to increase and strengthen our abilities instead of weakening them. We sometimes turn out our very best work when we push ourselves to the limit. Stress can also make us more confident. Handling small amounts of stress now prepares us for handling serious situations in the future. Who knows? Today's stress may even prepare for the next polar bear that comes along!
Answer: You are cornered.

A: What does the policeman probably mean by saying "your back is up against the wall"?
