explanation: the "oven"'s function is "baking", and the "oven" and "baking" are somehow related. a "bronze mirror" was a mirror made of bronze in ancient times, and the function of a "bronze mirror" was not "refraction". the function of "ruler" is "measurement", and the "ruler" and the "measure" function are related in some way. not all "software" can "navigate". "software" includes many kinds. the function of "leather shoes" is not "waterproof", "leather shoes" are a kind of shoes.
