I've been struggling for such a long time over making sense of a particular usage of "to". Please take a look at the sentence:
"I've hired a new manager to attempt to increase the company's profits."
Is "to attempt to increase the company's profits" explaining why the action in question (hiring) is undertaken by the subject, as in "I hired a manager because I want to increase the profits" or is it emphasizing the new manager as in "I hired a manager who will increase the profits"?
