premise: Man observes a wavelength given off by an electronic device.
hypothesis: The man is yodeling in a gondula.
explanation_1: Observing and yodeling aren't similar actions.
explanation_2: The man is either observing a wavelength or yodeling in a gondula; it is unlikely he does both at the same time.
explanation_3: A man who observes a wavelength is not a man yodeling in a gondola.
