question: ears:hearing aids
choices.label: A B C D
choices.text: eyes:telescope fingers:gloves lips:mask legs:crutches
explanation: "hearing aid" is the auxiliary tool of "ear", and "ear" and "hearing aid" have a connection between tool and character identity. the "telescope" can make the "eye" see further, and the "telescope" is an auxiliary tool for the extension of the "eye". "fingers" can be protected by "gloves", which are protective tools for "fingers". there is no obvious logical relationship between "mask" and "lips". "crutches" can assist "legs" to walk, and "crutches" are auxiliary tools for "legs and feet" recovery, which is consistent with the logical relationship of the query.
