Final answer:
The question seems to be about Oliver receiving a locket for good behavior but lacks specifics; it may reference 'Oliver Twist' where Oliver is adopted but the locket is a symbol rather than a reward.
Step-by-step explanation:
The question regards the age at which Oliver can get the locket if he has been good. However, the information provided does not give specifics about Oliver's age or the conditions for receiving the locket. The reference to a novel and its final climax suggests that the question may be related to a literature class, possibly discussing a plot point in a novel such as 'Oliver Twist' by Charles Dickens.
In the context of the novel, Oliver is adopted by good people at the end, but the locket is not directly tied to his behavior or a specific age. It is instead a symbol of his true heritage and innocence.
