A major art theft from a museum was remarkable in that the pieces stolen clearly had been carefully selected. The criterion for selection, however, clearly had not been greatest estimated market value. It follows that the theft was specifically carried out to suit the taste of some individual collector for whose private collection the pieces were destined. The argument tacitly appeals to which one of the following principles? ['Any art theft committed at the direction of a single individual results in a pattern of works taken and works left alone that defies rational analysis.', 'The pattern of works taken and works left alone in an art theft can be particularly damaging to the integrity of the remaining collection.', 'The pattern of works taken and works left alone can sometimes distinguish one type of art theft from another.', 'Art thefts committed with no preexisting plan for the disposition of the stolen works do not always involve theft of the most valuable pieces only.']
