question: panic:earthquake
choices.label: A B C D
choices.text: tax:gap backwardness:closure natural disaster:man-made disaster inferiority:discrimination
explanation: "earthquake" leads to "panic". the reason for the "gap" is not "tax", and there is no obvious logical relationship between the two. "closure" leads to "backwardness". "backward" is caused because of "closure". both "natural disasters" and "man-made disasters" are disasters, and "man-made disasters" do not lead to "natural disasters". "inferiority" and "discrimination" have no obvious logical relation.
