explanation: "probability" can also be called "possibility", and the concept of "logic" includes "probability" and "possibility". "siamese" can also be called "twin", and the concept of "biology" includes "twin" and "siamese". "report" can also be called "coverage", but the concept of "physics" does not include "report" and "coverage". "rejection" and "acceptance" have opposite meanings. there is no obvious logical relationship between "exhibition" and "strategy".
