question: smog:pollution control
choices.label: A B C D
choices.text: life:marriage waterlogging:drainage plague of insects:reduced yield capital:manage
explanation: after the occurrence of "smog", "pollution control" is required, and "smog" corresponds to "pollution control". "marriage" is a stage that "life" may go through. "life" does not necessarily require "marriage". after "waterlogging" occurs, "drainage" is needed. "waterlogging" corresponds to "drainage". a "plague of insects" will lead to "reduced yield". the two belong to a causal correspondence, which is inconsistent with their corresponding relation in the query. One can "manage" the "capital".
