I have two questions regarding adverbial adjuncts.
The first one is, in the sentence "The report adds that divorce can have both short-term and long-term effects on children"
Is "on children" a prepositional phrase functioning as an adverbial adjunct, or is it included in the noun phrase direct object? And if it is an adjunct, what kind of adjunct is it?
The second questions is about this sentence:
"Three mechanisms are given for the prospective effect of marriage, the main one being that it acts as a buffer against stress and anxiety."
Is "For the prospective effect of marriage" an adverbial adjunt of reason or an adverbial adjunct of purpose?
