choices.text: male teacher:young woman real number:positive number mammal:platypus humanities:chemistry
explanation: "butterflies" are not "viviparous animals". there is no obvious logical relationship between "male teacher" and "young woman", and their meanings are not similar. "positive numbers", negative numbers and zero are all "real numbers", and "positive numbers" are a kind of "real numbers" "platypus" belongs to "mammal". in China's high schools, the teaching courses are generally divided into "humanities" and science. "chemistry" does not belong to "humanities", but science.
