explanation: a "diamond" is a "stone", and a "diamond" is expensive. a "rolls-royce sedan" is a "car", and a "rolls-royce sedan" is expensive. "parma" ham is a kind of "ham", but "parma" is not a "ham". "water" is part of "tears". a "piano piece" is a kind of "music", but the general price is not a measure.
