premise: A man in a button up shirt with a black shirt underneath presents in front of a television.
hypothesis: A man prepares to give a speech for a television audience.
explanation_1: The first sentence only implies the man is presenting in front of a television, not necessarily that he is preparing a speech for an audience.
explanation_2: Not everyone who presents information also prepares to give a speech. Not all who are in front of a television present for a television audience.
explanation_3: Just because a man is on television does not mean they're giving a speech.
