Answer:
A, C, (maybe) D
Explanation:
Standard of living is a given, because it's something that can be seen or experienced. If people are only able to obtain a certain amount of education then, it either has to do with the government or people have to work to provide for their families.
D might be an option because depending on who is elected for what, could determine whether a country will make progression, or reverse back onto it's problems and get worse.
Hope this helps!
