premise: A boy and a girl sit at a black table, while a second boy sits near them on a windowsill.
hypothesis: There are boys and girls sitting at a table
explanation_1: If a boy and a girl sit at a black table then they are sitting at a table.
explanation_2: A boy plus a second boy make for two, so we can refer to them as plural and generalize by saying "boys and girls".
explanation_3: A boy and a girl are sitting at a table.
