People do not analyze every problem they meet. Sometimes they try to remember a solution, from the last time they had a   36   problem. They often accept the opinions or ideas of other people. Other times they begin to act without  37  , they try to find a solution by trial or error.  38   , when all of these methods   39  , the person with a problem has to start analyzing. There are six  40   in analyzing a problem.

  41   the person must recognize that this is a problem. For example, Sam's bicycle is broken, and he cannot ride it to class as he usually does. Sam must   42   that there is a problem with the bicycle.

Next, the person must find the problem.  Before Sam can repair his bicycle, he must know why it does not work.  For example, he must  43   the parts that are wrong.

Now the person must look for   44   that will make the problem clearer and lead to  45   solutions.  For example, suppose Sam decides that his bicycle does not work because there is something wrong with the brakes.  46   , he can look in his bicycle repair book and read about brakes, talk to his friends at the bike shop, or look at his brakes carefully.

After  47   the problem, the person should have  48   suggestions for a possible solution.  Take Sam as an example   49   , his suggestions might be: tighten or loosen the brakes ; buy new brakes and change old ones.

In the end, one   50   seems to be the solution to the problem. Sometimes the  51   idea comes quite  52   because the thinker suddenly sees something new or sees something in a different way. Sam, for example, suddenly sees there is a piece of chewing gum (笥�稾�) stuck to a brake. He   53   hits on the solution to his problem: he must 

  54   the brake.

Finally the solution is  55   Sam does it and finds his bicycle work perfectly. In short, he has solved the problem.
