and then prediction has been done "prediction is one of progressively shorter time spans for marriages" . All the factors that contribute or strengthen based on less matched logic should be eliminated.
a) An extremely fast moving society. ( leads to shorter span of marriage -- strengthen)
b) Life expectancy has gone up. ( neutral at best -- I think)
c) People are being less and less career minded. ( to strengthen People are being more and more career minded then we can predict or say shorter marriage) -- weaken
d) Men and women are becoming more and more competitive. ( strengthen the shorter marriage logic)
e) (b) and ©
For 2. I think B is the answer :- logic as The U.S. adult population's average age will increase between 1995 and 2005 so will be the incidence of diseases as mentioned. Thus average age of population with disease will move to aging side.
