premise: A rocker standing with one foot on the stage holding the microphone attached to the stand over his head.
hypothesis: A rocker is doing soundcheck for his performance by speaking into the microphone.
explanation_1: Doing a soundcheck doesn't mean they are standing with one foot on the stage. Speaking into a microphone doesn't mean it's attached to a stand over his head.
explanation_2: A rocker standing holding the microphone attached to the stand over his head don't necessarily imply a rocker is doing soundcheck for his performance.
explanation_3: A rocker is standing on stage holding a microphone, but that does not mean he is speaking into the microphone or doing a soundcheck.
