The independent variable is the one you control, and the one you test something against. It can be adjusted to a precise manner to see what sort of variation can be obtained in the results. The dependent variable is the output of the test, and is the one that changes as you change the independent variable, i.e.
It is dependent on the independent variable. An example would be the rate of evaporation from a plant as a function of air temperature. The air temperature is the independent variable, as its value does not depend on the rate of evaporation, and you can change the temperature yourself.
The rate of evaporation is the dependent variable, as this will change depending on the air temperature.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
