Since the zoo has more animals than enclosures, and every animal lives in an enclosure, it must be true that at least one of the enclosures contains more than one animal. The argument above exhibits a pattern of reasoning that is most closely paralleled by which one of the following? ['Since every year there are more marriages than divorces, there must be some marriages that will not end in divorce.', 'At least one of the families in Herndon has more than one child, since in Herndon, there are fewer families than children and every child is a member of a family.', 'Since boys under ten slightly outnumber girls under ten and since some families have more than one child under ten, it follows that at least one girl under ten has more than one brother under ten.', 'There must be fewer families that include teenagers than there are teenagers belonging to such families, since there is at least one family that includes more than one teenager.']
