premise: Six seated men converse and one man fiddles with an interesting contraption.
hypothesis: Several men are gathered to learn about ham radios.
explanation_1: Just because the men are sat near each other doesn't mean they are gathered together. The interesting contraption being used by one man does not imply that it is a ham radio.
explanation_2: They assembled not only to talk about ham radios.
explanation_3: seated men converse and one man fiddles with an interesting contraption does not imply that they learn about ham radios.
