Suppose you know that there is a strong negative correlation between the amount of daily exercise...?

My preference here is B.... D indicates a population is focused on....it could be wrong for that particular population... It just talks about negative corr. Of exercise and b.p. A is out.

Never mentions cause... C is out....talks nothing about who.....

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.
