explanation: both "red" and "blue" are the colors of "flowers". "flowers" have other colors besides "red" and "blue". "peace" and "war" contradict each other. "pass" and "up to the standard" are close in meaning. the "plain" refers to a large area of ​​"land" without trees, buildings or huge rocks."land" and "sunshine" do not have a logical relationship obviously. both "physics" and "chemistry" are types of "knowledge", and there are other types of "knowledge" besides these two.
