explanation: "color screen" is a kind of "screen". "nano meter" is a unit of length. "time" and "nano meter" have no obvious logical relationship. "amoxicillin" is a kind of "medicine". "extreme heat" refers to a very hot summer. "air conditioners" may be used for cooling during "extreme heat", which is not a kind of "air conditioner". the "cynical youth" is a kind of "youth".
