World war II ended in 1945, it looks like there was a large decline right after in 1946. The cold war began in 1947 until 1991, which is not seen on the graph. But yes, I would say C is the best answer.
A, cant be proven with this graph.
B Nothing about the soviet union on this graph. (unless there is another graph about the soviet union on your quiz?)
D, Wrong because it was at its lowest in 1946 not its highest
I'm leaning towards false for both.

I believe the answer is: Family
In tribal african culture, each members of the family would stick and live together even after the children grow up and got married. They would probably see the concept of leaving the parents at nursing home as immoral since they see taking care of your elders as a kind of repayment for back when they're being nursed as a child.
