Official Explanation
The word “however” in the second sentence indicates that Jean—who “exercises a self-discipline”—is very different from most teenagers. Therefore, teenagers are not associated with selfdiscipline. For blank (i), the phrase that most closely matches is “practiced restraint.” “Silent obedience” doesn’t quite match and “urbanity” means polite, confident, or polished. For blank (ii), the idiom “verges on” indicates that the word will mean some extreme form of self-discipline. The best word for that is “asceticism” (a lifestyle of extreme self-denial). “Asperity” (harshness in tone or temper) is tempting but usually refers more to emotions or weather conditions. For blank (iii), the words “whether” and “or” indicate that the blank will describe the opposite of a “conservative upbringing.” The best match is “permissive.” Jean might want to react to a “meddlesome,” or very intrusive, upbringing, but it’s not the opposite of conservative. Don’t be tempted by “illiberal,” which means narrow-minded or bigoted.
