only after reading the replies, I think it is 3
so only after reading the replies, huh?
answer is indead (c), although i have chosen (a). we can not assume anything, right? we are given a fact: father does not know anything about child. if not (a), then it means we are digging deeper than we have to. okey, let's dig deeper in case of (c). there are a lot of high-qualified lawyers out there, who can prove you that father is the victim of this policy and now he has all rights to get his child back, since he is the born father of his son and he really loves him bla bla bla...
okey, here is the explanation:
you are looking for the best reason why ms. s. should not be worried, and (c) provides it. the new policy that the adoption agency has put into place requires that all adoptions be approved by the birth father, so he has signed away his right to sue for custody. if (a) and (b) are true, then the father could still sue if he wanted. (d) and (e) are irrelevant, because age was never mentioned as an issue, and neither was the number of children that ms. s. has adopted.
