explanation: the purpose of "wealthy" must be achieved through "poverty alleviation". "drying" is achieved by "dehumidifying". to avoid "ignorance", one must pass "education", and "ignorance" is not the purpose of "education". there is no obvious logical relationship between "backwardness" and "advancement". "health" will be "defend".
