Decision-thinking is not unlike poker --it often matters not only what you think, but also what others think you think and what you think they think you think.The mental process is similar.Naturally,this card game has often been of considerable interest to people who are,by any standards,good thinkers. The great mathematician John von Neumann was one of the founders of game theory.In particular,he showed that all games fall into two classes:there are what he called games of  'perfect information', games like chess where the players can't hide anything or play tricks:they don't win by chance,but by means of logic and skills.Then there are games of 'imperfect information', 1ike poker,in which it is impossible to know in advance that one course of action is better than another. One mistaken idea about business is that it can be treated as a game of perfect information.Quite the reverse.Business,politics,life itself are games which we must normally play with very imperfect information.Business decisions are often made with many unknown and unknowable factors which would even puzzle best poker players.But few business people find it comfortable to admit that they are taking a chance,and many still prefer to believe that they are playing chess,not poker. The subject discussed in this text is   _ A) the process of reaching decisions B) the difference between poker and chess C) the secret of making good business plans D) the value of information in winning games

The other day I was watching Sportscenter when one of those "human interest " stories came on and really caught my attention. The hero was about a 27-year-old professional Bass Fisherman named Clay Dyer. At first, they played it off as another guy trying to make the cut on the Bassmaster tour until they showed a picture of him. No legs, no arms, or rather, he was only1/3 of his right arm. That's all that he has. It was such an amazing story that I was wondering what this guy could do. Growing up, he learned to play baseball and basketball, but found that fishing was his true calling. And he does it all on his own. He holds the fishing pole under his chin and uses that and his stub arm to cast and reel in the fish. He uses his teeth to help him unhook fish. He ties his own hooks on with his mouth, never really asking anyone else to help. Clay Dyer even knows how to swim. Since his body can't produce enough sweat on its own, he has to take a dip in the lake every few hours to keep cool. He dives in just like anyone else, then somehow treads water  with his stub arm, then, with a little help, pulls himself back up into the boat and goes on fishing. Clay Dyer has never looked for others' pity, nor has he allowed his physical disabilities to prevent him from becoming a professional fisherman. His motto for life is "If I can, you can."He refuses to use special equipment, saying, "I want to do it with one hand the way they do it with two. The text is intended to  _  . A) persuade readers to watch Sportscenter. B) share Clay Dyer's life story's with readers. C) call on readers to care for the disabled man. D) express the author's admiration for Clay Dyer.
