explanation: the reason for "freezing" is "cooling down", and the characteristic of "freezing" is "hardness". the causes of "extinction" are "famine" and "hunting". "metal" will be "cut". the cause of "infection" is "contact", and the characteristic of the "infection" is "cough". the basis of "operation" is "counting". there is "counting" first and then "operation". the corresponding relationship is inconsistent with the query.
