We have two people talking about families: T says that family is DECLINING and MUST return to what it was; J says that it's GOOD ENOUGH as it is currently.
Trisha: Today’s family is declining in its ability to carry out its functions of child-rearing and providing stability for adult life. There must be a return to the traditional values of commitment and responsibility.
Jerod: We ought to leave what is good enough alone. Contemporary families may be less stable than traditionally, but most people do not find that to be bad. Contemporary criticisms of the family are overblown and destructive.
Trisha and Jerod disagree over whether the institution of the family is
(A) adequate as it is
Yep, the answer. But let's see what the other choices say.
(B) changing over time
Both parties essentially state that family has changed over time. This isn't a point of disagreement between them therefore.
(C) valued by most people
Not mentioned at all I daresay. At least not in terms of disagreement.
(D) not going to survive
Not mentioned by either party.
(E) no longer traditional
Both agree with this view, so it's not really a point of contention between them.
