根据短文内容选择最佳答案。
Once there was something wrong with a machine in a factory.The workers could do nothing but turn to a German engineer for help, who drew a line on it and then said,“Take off the part where the line is and change it for a new one.”The machine, with a new part, began running well again.The engineer then asked for $30,000 for what he had done.The following were what he wrote on a bill,“The new part only costs one dollar, and knowing where the problem with the machine is costs $29,999.”
One dollar for changing a new part sounds reasonable(有道理的)but the $29,999 is exactly the value(价值)of wisdom(智慧)and knowledge.
