Even it is different but at least there things that people here on QL agree on, but problem come from those who to say that there is only one source for a major problem and these people forget that this major problem is due to other small problems, here are some examples:

example1   House fire is because small fire

                  Small fire is because of spark

                  spark is of static electricity or children playing with matches

example2   Car accident maybe because break pad problems or tire burst

                  Break Pads are worn out and tires are because no proper check

example3   Feet injured and bleeding because of crushed glass on floor

                  crushed glass on floor because of broken glass

and we can build many other examples and I will keep the solutions of the above examples for you guys.
