C) percentage of the population that is willing and able to work is declining. The labor force is made up of those who are employed, plus those who are unemployed but who want to work, and are actively seeking work. You can get the unemployment rate from taking the second group of people on this list, and dividing by the sum of both groups.
But that is not what the quesiton asks you. The labor force participation rate is the labor force as defined above divided by the population. This is another way of saying what your answer choices say, which is the percentage of the population that is willing and able to work.
They are just two ways of saying the same thing, so when one declines, the other declines also.
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.
