explanation: both "cypress" and "pine" are "trees", and "cedar" is a type of "pine". both "automobile" and "train" are "car", and "motor car" is a kind of "train". the basic principle of "civil law" is to protect the legitimate civil rights and interests of "citizens" and legal persons, and a "citizen" is not a "law". "pear flower" and "fragrant pear" belong to the corresponding relationship between flowers and fruits, and "fragrant pear" does not belong to "flower". "bezoar" is the gallbladder stone of "ox" (a few are bile duct stones), and "bezoar" is a component of "cattle".
