question: west lake:taihu lake
choices.label: A B C D
choices.text: metropolis:parliament computer:human brain boy:girl addition:division
explanation: "west lake" and "taihu lake" are both freshwater lakes, and there are other lakes besides these two. "metropolis" means city, while "parliament" is the legislature of a democratic country. there is no obvious logical relationship between "metropolis" and "parliament". "computers" simulate the thinking of the "human brain", and "computer" corresponds to the "human brain". "boys" and "girls" contradict each other. "addition" and "division" are both mathematical operations, which are more than "addition" and "division", including multiplication and subtraction.
