This conclusion also has a chance of being faulty.
There exists a chance of error in both of the final decisions sought over in the above description. To ensure our conclusion even more we enter our house once more and turn on the switch of another lamp to check whether it turns on or not. If this new lamp also would not turn on then it would be certain that there is no electricity in the house. The way this would be scientifically assessed is narrated a follows:
Analysis: Either the bulb would glow or it would not glow. If the bulb glows in the second lamp then it may be decided that there has been a fault in the wiring of the initial lamp that was attempted to be turned on when the person reached home. There exists the possibility of a POSSIBLE ERROR here and that is that the lamp may not have been plugged into the socket properly.
Just as the possibility of the lamp not being plucked into the socket was discussed, this possibility may also be assumed for the initial lamp. Hence the hypothetical testing of possibilities behind the non- functioning of the lamp continues unless and until all possible situations have been addressed.
If the water is not coming out of the main water outlet then there arise two possibilities. Either there is no water in the overhead task or the tap has malfunctioned and is not letting water through. In order to clarify this situation the following scientific experiment is conducted:
Analysis: If there is now water emission from any of the taps within the house then it may well be concluded that there must not be any water in the overhead water tank. However, if water is coming out of the other taps it may be assessed that there might be an airlock in the tap of the Garage that restricted water from coming out of it.
Thus it was decided that if there was no water in the overhead tank then the tank would be filled by turning the water filling motor on. On the other hand if only the garage tap would
