People do not analyze every problem they meet. Sometimes they try to remember a solution, from the last time they had a   1   problem. They often accept the opinions or ideas of other people. Other times they begin to act without   2   , they try to find a solution by trial or error.  3   , when all of these methods   4  , the person with a problem has to start analyzing. There are six   5   in analyzing a problem.
6   the person must recognize that these is a problem. For example, Sam's bicycle is broken, and he cannot ride it to class as he usually does. Sam must   7   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   8   the parts that are wrong.
Now the person must look for   9   that will make the problem clearer and lead to  10 solutions. For example, suppose Sam decides that his bicycle does not work because there is something wrong with the brakes.   11  , 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   12   the problem, the person should have  13   suggestions for a possible solution. Take Sam as an example   14  , his suggestions might be: tighten or loosen the brakes; buy new brakes and change old ones.
In the end, one  15   seems to be the solution to the problem. Sometimes the   16  idea comes quite   17   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 (口香糖) stuck to a brake. He  18   hits on the solution to his problem: he must   19   the brake.
Finally the solution is   20 . Sam does it and finds his bicycle works perfectly. In short he has solved the problem.
