A little confusion about these sentences. 1.Banks have different policies and the services that they will offer you will depend on your individual circumstances and on the discretion of the bank manager involved. Q: Which word is the last word "involved" used to describe? "Discretion" or "Manager"? 2.Adequate heath-care resources are provided out of the public purse. Q: Why did the writer use "provided out of "? Why not use "provided by "? Both of these two sentences come from the Cambridge Ielts. Thanks for responses.
