After entering a dark room, you turn on a light switch, but the light does not come on. Please suggest three different hypothesis that might explain your observation. Please also note how you might test these hypotheses and describe what observation(s) may lead you to conclude that one of the hypothesis is correct.

Explanation:

The three possible hypothesis for light not to turn on immediately after one on the switch are;

We test the first hypothesis, how?

We check if other electronics connected to the same sources of power supply as the bulb is working. If the electronics are not working, then the first hypothesis is correct but if they are working then the hypothesis fails and we move on to test the next hypothesis.

To test for the second hypothesis as the first hypothesis fails, we remove the bulb and fix it into another socket which has a working switch. If the bulb comes on then the second hypothesis is correct but if the bulb does not turn on then the hypothesis fails so we move on to test the third hypothesis.

As the bulb fails to turn on in our initial socket and a second bulb is fixed in that same socket and it came on, then the third hypothesis is correct.
