question: ears:hertz
choices.label: A B C D
choices.text: skin:temperature nose:smell tongue:taste buds eyes:wavelength
explanation: "ear" belongs to the five senses, which can identify sound waves within a specific range, and "hertz" is a physical quantity that can express the number of times a sound wave vibrates in a unit time. the level of "temperature" can be felt by the "skin". "temperature" is a physical quantity that expresses the degree of heat and cold of an object, but "skin" is not one of the five senses. "nose" can distinguish "smell", "smell" is not a physical quantity. "tongue" contains "taste buds". "eyes" belong to the five senses, which can identify light waves within a specific range, and "wavelength" refers to the distance the wave travels in one vibration cycle.
