premise: People seated at long tables all facing the same direction, some writing and some watching.
hypothesis: A family reunion is in progress as relatives sit at tables and write down each other's addresses.
explanation_1: You can not infer it's a family reunion.
explanation_2: People seated together are not necessarily at a family reunion, and we cannot tell if they are writing down each other's addresses.
explanation_3: People choosing to write at tables does not necessarily mean that they are there for the purpose of a family reunion.
