What is the title of this article:

Not all boys who pass the College election examination choose to become King's Scholars. If they choose instead to belong to one of the 24 Oppidan Houses, they are known as Oppidan Scholars. Oppidan scholarships may also be awarded for consistently performing with distinction in School and external examinations. To gain an Oppidan Scholarship, a boy must have either three distinctions in a row or four throughout his career. Within the school, an Oppidan Scholar is entitled to use the letters OS after his name.
