The greatest failure of modern American society is its rejection of the extended family. It is no wonder our society is so violent and so many Americans feel a deep sense of isolation and overwhelming stress.
This argument is based on all of the following
assumptions EXCEPT -> 4 correct assumptions in options. Spot these 4!
Let's jot down the points:
Premise: Biggest failure of mod Amer society-no extended family
Conclusion: That is why, society violent and many Americans feel isolated and stressful.
A. Americans value independence more than interdependence. -> okay Americans value independence > interdependence but I honestly don't find any connection of this sentence with the argument. So better to move forward and choose proper 4 assumptions and the 5th option will be the answer.
B. people who live in extended families feel less stress. -> Yes. Definitely possible assumption. No wonder why modern families feel so isolated.
C. a large percentage of Americans feels isolated and alone. -> This assumption is kinda possible because modern Americans don't go for extended families so such feelings are possible.
D. living in an extended family engenders a strong sense of belonging. -> similar explanation as option B
E. deep feelings of isolation and overwhelming stress lead to antisocial and violent behavior. -> Possible assumption.
According to me, option B to option E directly or indirectly connected itself with premise and conclusion. Assumptions must always link itself with the premise and conclusion. Now it is safe to confirm that
option A (IMO) is the correct answer here since it can't be the assumption to this argument.
