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 .

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.1.The subject discussed in this text is __________.A. the process of reaching decisionsB. the difference between poker and chess.C. the secret of making good business plansD. the value of information in winning games2.An important factor in a game of imperfect information is __________.A. rules B. luck C. time D. ideas3.Which of the following can be used in place of “Quite the reverse ” in Paragraph 3 ?A.
