Premise:
"Even assuming, for example, that the Congress and the President adhere to the oftenstated goal of saving the Social Security surpluses, our longterm model shows a world by 2030 in which these three programs alone would require almost threequarters of total federal revenue." Based on this premise, is the hypothesis "According to our model, these three programs would require almost two thirds of total federal revenue by 2020." true?
it is not possible to tell
